A storm swept over Mercedes and up turned a great tree. The next day in the earth that still clung to the upturned roots, he caught the glitter of gold and upon examination thirty pieces of ancient gold craft were found. The great tree had grown over the grave of some for- gotten chief and its roots had enmeshed the funeral offerings. In addition to long continued excavations at Mercedes, supplementary work was carried on in other parts of Costa Rica.

The Committee for Cultural Policy, Inc. (CCP) and Global Heritage Alliance (GHA) submitted testimony to the Cultural Property Advisory Committee regarding the proposed renewal for an additional five years of Costa Rica’s 2020 Memorandum of Understanding (MOU) with the United States under the 1983 Cultural Property Implementation Act. The 2020 MOU imposed wide ranging, comprehensive, restrictions on the importation of ancient and ethnographic art from Costa Rica into the United States. The testimony was presented to the Cultural Property Advisory Committee for a hearing on May 20, 2025.

Introduction

Honorable members of the Cultural Property Advisory Committee (CPAC), The Committee for Cultural Policy (CCP)[1] and Global Heritage Alliance (GHA)[2] respectfully submit this testimony regarding the proposed renewal of the Memorandum of Understanding (MOU) between Costa Rica and the United States. This testimony aims to provide a comprehensive overview of the legal framework governing Costa Rica’s cultural heritage protection, the historical and modern motivations for looting archaeological sites, and the ongoing challenges facing both the protection of Costa Rican archaeological sites and the legal access for the public, for scholarship, and for cultural institutions to that nation’s ancient and ethnological art.

Executive Summary

The renewal of import restrictions is not justified under the CPIA’s legal requirements: there is a lack of documented evidence of ongoing looting in Costa Rica’s archaeological sites, a core prerequisite for such restrictions. Past instances of looting, while regrettable, occurred decades ago and cannot alone justify new or continued import restrictions. Moreover, other key statutory criteria mandated by Congress – including Costa Rica’s self-help measures, the scope of objects covered, and the existence of a concerted international response – have not been met. In addition to these legal shortcomings, renewing the MOU raises broader policy concerns about fairness to collectors and museums, transparency of the process, and negative impacts on academic research and cultural exchange. For these reasons, we urge the Cultural Property Advisory Committee (CPAC) to recommend against renewal of the MOU unless Costa Rica can both substantiate a current looting threat meeting the criteria under the CPIA and undertake the meaningful remedial actions that the law requires for an MOU.

The CPIA was enacted to combat current illicit excavation and trafficking of cultural objects – not to address looting from decades past. Under U.S. law, import restrictions may only be imposed if the cultural patrimony of the requesting nation “is in jeopardy” from present-day pillage. In the case of Costa Rica, neither the Costa Rican authorities nor the U.S. State Department have provided any evidence that significant looting of archaeological or ethnological materials is occurring in the country today. On the contrary, available information indicates that large-scale looting in Costa Rica was primarily a historical phenomenon (for example, during the late 19th and 20th centuries) and has diminished in recent decades. Likewise, the State Department has not released any public summary detailing recent looting incidents in Costa Rica.

The American Museum journal, c1900-(1918), American Museum of Natural History.

Because no current looting crisis has been documented, the fundamental legal basis for extending import restrictions is absent. CPIA import restrictions are meant to address a situation in which a source country’s heritage is under immediate threat – a threshold that has not been met here. Past looting alone, however extensive it may have been in the 19th or 20th century, is insufficient to satisfy the CPIA’s requirements for new or renewed restrictions. Congress did not intend for the U.S. to restrict imports of cultural property simply to remedy historical wrongs or to enforce foreign ownership laws in a vacuum; rather, the law targets ongoing pillage. Absent hard evidence that Costa Rica’s archaeological sites are currently being pillaged on a significant scale, CPAC cannot make the necessary finding that Costa Rica’s cultural patrimony “is in danger” – and thus cannot lawfully recommend renewing the MOU.

There is no evidence that the United States is a major market for Costa Rican antiquities. It thus fails to meet a primary criterion of the CPIA requiring a concerted international response. On the contrary, long before the imposition of import restrictions in 2020, in data collected from 2016 and before, the U.S. was one of the smallest art market nations historically, totaling approximately $37,000, completely dwarfed by France’s auctions ($1.9 million) and considerably surpassed by both Belgium and Germany.[3]See Appendix A, Costa Rican Artifact Sales By Country, below.

CPIA’s Legal Thresholds for Import Restrictions

Beyond the lack of any demonstrated looting threat, the proposed MOU renewal fails to meet several other strict legal criteria set forth in the CPIA (19 U.S.C. §§ 2601–2602). Congress deliberately imposed these thresholds to ensure that import restrictions are exceptional measures used only under well-defined circumstances, and all must be satisfied for an MOU to be justified:

  • Imminent Threat (Pillage of Cultural Patrimony): The requesting country’s cultural patrimony must be in jeopardy from current pillage of archaeological or ethnological materials. This means there must be ongoing looting or illicit excavation putting the nation’s heritage at risk. Costa Rica has not provided evidence that its sites are presently under such threat.
  • Self-Help Measures: The source nation must be taking meaningful self-help measures to protect its cultural heritage domestically. Under the CPIA, CPAC must determine that “Costa Rica has taken measures consistent with the [UNESCO] Convention to protect its cultural patrimony”. This includes enacting and enforcing laws, guarding sites, educating the public, and other efforts on the ground. To date, there is little indication that Costa Rica has significantly improved its site security or enforcement of restrictions on commercial and infrastructure development of heritage sites. By all accounts, Costa Rica could do much more to police and manage its own cultural resources.
  • Concerted International Response: U.S. import restrictions must be part of a concerted international effort of similar measures by other major art-market nations. As noted above and in Appendix A, auction houses in France have sold fifty times the total U.S. auction sales.[4] The CPIA does not authorize unilateral U.S. action if it would simply divert the illicit trade elsewhere. In the case of Costa Rica, however, there is no sign of comparably broad restrictions to those in the current MOU being implemented by other market countries.
  • Defined Scope of Cultural Material: Any restrictions must apply only to narrowly defined categories of objects that truly constitute Costa Rica’s archaeological or ethnological patrimony. The CPIA’s definitions strictly limit what can be restricted: objects must be of cultural significance, at least 250 years old in the case of archaeological material, and first discovered within Costa Rica (and subject to its export control). This means that common or repetitive items – what Congress called “trinkets” – and objects widely found outside of Costa Rica should not be subject to restrictions. However, the past MOU and designated list is overbroad, covering items like ordinary pottery, tools, and other materials that do not meet the CPIA’s criteria of exclusive discovery in one country or cultural significance. CPAC must ensure that any list of protected categories remains tightly focused and omits objects that fall outside the CPIA’s scope. In particular, items that are widespread in the region or not uniquely tied to Costa Rican context (for example, certain colonial-era artifacts or coins minted in the millions) cannot lawfully be restricted.
  • No Less-Drastic Alternatives: The CPIA also requires a finding that remedies less drastic than import restrictions would not suffice to protect the cultural patrimony. Import bans are meant to be a last resort. CPAC should consider whether other measures – such as targeted law enforcement cooperation, site security improvements, or licit artifact sourcing programs – could mitigate looting without burdening lawful trade. In Costa Rica’s case, encouraging the nation to adopt pragmatic solutions (for example, a portable antiquities registration scheme to legalize and track minor finds on private land) could significantly reduce looting incentives and enable legally privately owned antiquities dating to early collections to be exported. If such self-help alternatives have not even been tried, it is premature to impose or renew sweeping U.S. import restrictions.
  • Consistent with Cultural Exchange: Finally, the law mandates that any import restrictions be consistent with the general interest of the international exchange of cultural property for scientific, cultural, and educational purposes. This reflects Congress’s intent that restrictions not cut off museum loans, scholarly research, or public exhibition of art and artifacts. Overly broad or perpetual import blocks on Costa Rican material would hinder legitimate sharing of objects among scholars and institutions. The CPIA’s delicate balance envisions protecting artifacts while still permitting cultural exchange, not erecting permanent barriers between nations’ heritages.

In summary, the current MOU with Costa Rica – if renewed without change – fails to satisfy multiple CPIA requirements. There is no clear showing of a present looting threat; Costa Rica’s own protective efforts are lagging; the likely scope of restricted materials is too broad; and the continuation of blanket restrictions risks undermining cultural exchange. Where the CPIA’s criteria are not met, the United States must refrain from imposing import restrictions, or else adjust the agreement so that it conforms to the law’s narrow intent.

Early Trade in Costa Rican Artifacts

The American Museum journal, c1900-(1918), American Museum of Natural History.

Costa Rica’s pre-Columbian heritage – including ceramics, jade carvings, stone sculpture, and gold objects – has experienced centuries of looting and dispersal. The patterns of looting and trade have changed dramatically from the colonial era through the 19th and 20th centuries into the present day. In the colonial period, exploitation was driven by the search for precious metals and curios by Spanish colonizers. By the late 19th century and into the 20th, the antiquities of Costa Rica and the hitherto little-known pre-Columbian civilizations they represented were of increasing interest to collectors and museums, promoting their export. In the third quarter of the 20th century, popular collecting by individuals expanded significantly, but in recent decades, the expansion of national cultural property laws, the aging collector demographic and the fact that there are many thousands of pre-Columbia objects already in international circulation has meant that there is no longer sufficient market demand to trigger looting. Pre-Columbian objects are commonly found outside Costa Rica, especially in U.S. collection, and except for outstanding objects (rarely found in the Costa Rican context), they are not only a poor investment – their values are much lower than they were ten or twenty years ago.

Colonial Era: Exploitation of Indigenous Artifacts

The Spanish colonial period (16th–18th centuries) set the earliest stage for cultural heritage loss in Costa Rica. Christopher Columbus reached Costa Rica in 1502, and Spain gradually established a colony that, unlike other regions, had no rich gold or silver mines and only a sparse indigenous population after devastating epidemics. Lacking large civilizations like the Aztec or Maya, Costa Rica’s native cultures built with perishable materials, leaving few monumental ruins above ground. However, indigenous peoples possessed gold ornaments and ritual objects which Spanish settlers eagerly sought. The very name “Costa Rica” (“Rich Coast”) reflected Spanish hopes of finding precious metals. Colonial officials and missionaries often appropriated any gold artifacts they encountered, melting them down for bullion or church adornments (a common fate of indigenous gold across the Americas). This early exploitation was motivated by monetary value rather than scholarly interest, and many ancient items were lost forever to the crucible.

Unlike in Peru or Mexico, there were no large-scale antiquities excavations during the colonial era in Costa Rica – the colonial government even deemed the province “the poorest and most miserable Spanish colony in all America”[5] Nevertheless, by the late colonial period (late 1700s), some Europeans showed antiquarian interest in pre-Columbian objects, which would blossom in the 19th century. The stage was set for outsiders to later view Costa Rica’s archaeological heritage as collectible trophies.

19th Century Collectors and the Export of Antiquities

Book Illustration of objects from Mercedes, Costa Rica, Author Herbert Joseph Spinden, 1979-1967, Ancient civilizations of Mexico and Central America, 1917, American Museum of Natural History Library.

In the late 18th and early 19th century, Costa Rica’s antiquities began leaving the country in significant numbers, often as a byproduct of infrastructure projects and the activities of foreign entrepreneurs. As the country’s economy grew (coffee and banana plantations, road building, etc.), many previously undisturbed archaeological sites were unearthed during land development. Trade in antiquities developed alongside these primarily inadvertent discoveries of hitherto unknown sites, as artifacts were discovered during agricultural expansion and railroad construction. A pivotal figure was Minor C. Keith, an American railroad and banana plantation magnate who worked in Costa Rica in the late 1800s. During railroad construction and agricultural expansion, workers unearthed thousands of pre-Columbian artifacts, including ceramic vessels, stone sculptures, jade, and gold pieces. Keith amassed a huge collection of these archaeological objects, ultimately shipping an estimated 16,000 artifacts out of Costa Rica.[6] Upon his death, he bequeathed his collection to the Brooklyn Museum in New York.

Keith was not alone – other diplomats, scientists, and wealthy travelers in the 19th century collected Costa Rican antiquities. Costa Rica, however, took a step toward preservation in 1887 by creating the National Museum, signaling official concern for safeguarding heritage.[7] Despite this, regulation was weak or non-existent for decades. By the late 19th century, Costa Rican archaeological artifacts were finding their way into museum and private collections abroad. Keith’s collection remained abroad for over a century until 2011, when the Brooklyn Museum agreed to return roughly 1350 artifacts to Costa Rica (retaining only a study collection).[8]

Looting and removal of artifacts during the colonial period and later nineteenth century were motivated largely by exploitation and curiosity. Spanish colonizers sought gold and treasure, while 19th-century collectors like Keith saw archaeological pieces as exotic curios or scientific specimens. The concept of protecting ancient sites for their historical value was only just beginning to emerge.

Early to Mid-20th Century: Huaqueros and “Subsistence Looting”

The 20th century witnessed both an intensification of archaeological looting in Costa Rica and the first efforts to legally curb it. Farmers and laborers who encountered artifacts – stone metates (grinding tables), polychrome pottery, carved jade pendants, etc. – often dug further, knowing there was a ready market for these items.

History of the discovery and conquest of Costa Rica, Author Ricardo Fernández Guardia, 1867-1950, 1913, New York : T.Y. Crowell Co., Library: Robarts – University of Toronto.

By the early 20th century, word of Costa Rica’s buried treasures had spread, and local villagers frequently engaged in looting tombs for income. The phenomenon accelerated mid-century. For example, in 1939 a hurricane reportedly exposed a cache of gold objects on a banana plantation in the Diquís Delta, which spurred a frenzy of digging in the area (the Diquís region is famous for its stone spheres and gold). Throughout the 1940s–1960s, huaqueros supplied a growing international demand for pre-Columbian art. These looters were often impoverished farmers who saw artifacts as a rare source of cash. Anthropologist David Matsuda, who studied Central American subsistence diggers, noted that rural poverty was the primary driving factor – for many, looting was a means to buy “seed corn, food, clothes and security” for their families.[9] Matsuda recounts how diggers feel exploited by archaeologists and elites: one looter complained that academics treat them as “ignorant peasants” while they themselves profit from artifacts, whereas for the looters “these gifts from our ancestors mean seed corn, food… and security. This is how we live our lower-class lives.[10] Such testimony underscores that mid-century looting was often born of economic necessity and class inequity rather than wanton destructiveness.

During this period, the Costa Rican government began enacting laws to protect antiquities. In 1938, Costa Rica passed its first law (Law No. 7) controlling the exploitation and commerce of archaeological relics, and an accompanying decree established regulations.[11] This law essentially declared in situ archaeological objects the property of the state and sought to license excavations. However, enforcement remained limited in these decades. It was not until 1950 that the National Museum created an Archaeology Department, and not until 1982 that a comprehensive patrimony law (Law No. 6703) firmly asserted state ownership of all archaeological objects.[12] Thus, for much of the mid-20th century, despite laws on paper, looting continued relatively unabated in practice, especially in remote rural areas.

Late 20th Century: International Markets

From the 1960s -1990s, there was a dramatic expansion of personal art collecting of ethnographic and ancient art and Costa Rica’s artifacts became of interest to individual as well as institutional collectors in the United States, Europe, and Japan. Perhaps the most notorious figure of this era is Leonardo “Leo” Patterson, a Costa Rica-born antiquities dealer who came out of extreme poverty, who operated from the 1960s through the early 2000s. Patterson first became involved in the trade by buying gold artifacts from farmers (otherwise destined for melting) and reselling them, claiming he was “saving history” from the crucible. Over decades, he shipped thousands of archaeological objects from Costa Rica, often with tacit approval from officials – he was even rewarded with diplomatic postings by grateful politicians.

Operating primarily out of Germany, Patterson sold pre-Columbian artifacts to wealthy clients and major museums worldwide. His inventory ranged from common ceramics to objects of extraordinary value (jade figurines, gold masterpieces). He was celebrated in some circles – until law enforcement eventually caught up. By the 1990s and 2000s, Patterson faced accusations of trafficking looted heritage from multiple countries. He was indicted in the U.S., Spain, and Germany for dealing in illicit antiquities.[13]

Alongside Patterson, many lesser-known traffickers and local middlemen participated in moving Costa Rican artifacts abroad. Corruption played a role: in some cases, officials turned a blind eye or even participated. A scandal in 2011 illustrated this internal issue – that year, the Director of Costa Rica’s National Museum was fired after 100 artifacts were discovered hidden in her relatives’ home, presumably taken from the museum’s collections.[14]

By the late 20th century, there was a substantial international market for Pre-Columbian antiquities from Costa Rica, although it was far smaller than that for artifacts from Mexico, Peru, or Colombia. The most valued objects were intricately painted Nicoya polychrome vessels, carved stone metates and the enigmatic Diquís stone spheres.  A visible trade in Costa Rican antiquities has continued – though not for objects taken recently from Costa Rica, which the antiquities market avoids. Investigative website site Memoria Robada states that according to Costa Rican authorities, between 2010 and 2016, relics from Costa Rica appeared in at least 23 different auctions abroad.[15] The same group of investigative journalists later calculated that around 214 Costa Rican pre-Columbian objects were put up for sale in recent years at galleries and auction houses in the U.S. and Europe.[16] However, there is nothing to show that these were recently looted – or whether they came from collections made in the nineteenth or early twentieth century. A more specific accounting of the volume of such public sales for the purpose of determining if there is a significant market under CPIA standards is found in the art-reporting and auction database publisher Artkhade’s reports. According to Artkhade a total 875 Costa Rican antiquities have appeared in worldwide auction sales tracked by the database between 2009 and 2025, a little over fifty objects per year.[17] The Table below, excerpted from the same Artkhade report shows a few recent auction results for Costa Rican artifacts, showing typical sales prices ranging from $1240 to a high of €31,200. These numbers, representing artifacts collected over centuries and widely distributed worldwide is some of the best evidence that there is not an ongoing looting crisis in Costa Rica.

Artifact Origin/Type Auction Date Price Realized
Diquís stone figure Pacific southwest (Diquís) Dec 19, 2024 €15,600
Nicoya jade ceremonial mace head Nicoya/Guanacaste region Dec 12, 2024 €31,200
Las Mercedes stone head Atlantic railroad zone Dec 20, 2024 €4,056
Nicoya polychrome vessel Nicoya region (ceramic) Sep 27, 2024 $1,364
Nicoya ceramic figure (“maternity” figure) Nicoya region Sep 27, 2024 $1,240

Entering the 21st century, development patterns changed and Costa Rica transitioned from a primarily agricultural economy to one focused on services and tourism in recent decades, meaning fewer farmers randomly turning up artifacts in fields. As of a few years ago, Costa Rica had only 20 objects listed with Interpol as stolen.

Legal Framework and the Question of Private Ownership

Costa Rica object, Guide leaflet, c. 1901, American Museum of Natural History.

Like virtually all other countries, Costa Rica’s legal framework for cultural heritage has progressively strengthened over the past century – especially in the last forty years. A core issue within this framework is the status of private ownership of antiquities – what can individuals legally own?

1887 – National Museum established: This marked the start of state stewardship of heritage. The Museum conducted excavations and collected artifacts, but there was no comprehensive law yet vesting ownership in the state.

1938 – Law No. 7 “Control of the exploitation and commerce of archaeological relics”: This was Costa Rica’s first antiquities law, declaring that archaeological objects (movable and immovable) are part of the national heritage. Also in 1938, Decree No. 14 established regulations for permits. Although any artifact found after 1938 was supposed to be under state protection, in practical terms, few private individuals finding artifacts turned them over or even registered them.

1970s – International Conventions: Costa Rica joined the 1976 OAS Convention of San Salvador on protecting heritage (ratified by Law No. 6360 in 1979) and later the UNESCO 1970 Convention (implemented by Law No. 7526 in 1995). In 1971, Law 4711 required protective steps during construction projects– a measure to integrate heritage protection with development.

1982 – Law No. 6703 “Defense and Conservation of National Archaeological Heritage”: This is the first modern heritage legislation in Costa Rica. It reaffirmed that all archaeological objects (defined as those created by indigenous cultures before the Spanish conquest) are part of the public domain and cannot be privately owned or traded without permission. It created the National Archaeological Commission to oversee permits and the national inventory. The law criminalizes unauthorized excavation (saqueo), illicit trading, and destruction of archaeological sites. Penalties include 1 to 5 years in prison for serious offenses. This law also formally requires that any discovered artifact must be reported to the National Museum. Private owners who had legitimate collections predating the law were required to register them. No legal export is allowed except with government authorization (usually only for research loans or exhibits).

Related regulations: Decrees in 1989 and 1999 set detailed rules for archaeological research and for the functioning of the Archaeological Commission. In effect, permits are given only to qualified researchers, and all finds belong to the state.

Under these laws, private ownership of newly found antiquities is essentially prohibited. However, objects that were already in private hands before the laws (especially before 1938 or 1982) presented a tricky situation. Many wealthy Costa Rican families and foreign collectors possessed artifacts acquired in earlier times. The law does not outright confiscate those (to avoid legal challenges in which private owners have succeeded in the past), but it declares them part of the national heritage and typically requires registration with the National Museum. In practice, some latitude was given for old collections, which could be kept by owners (often as family heirlooms) but could not be exported or sold commercially within Costa Rica. Any transfer of such items is supposed to be reported.

An investigative report in La Nacion in 2016 stated that between 2010 and 2017, “40 operations were carried out involving officers from the Miscellaneous Crimes Section of the Judicial Investigation Agency (OIJ) and archaeologists from the National Museum.

During those seven years, 4,066 of the 10,000 objects that had been in private possession since 1982, when the law prohibiting their possession and trade was passed, were seized.”[18] Of these, “17 operations targeted merchants, eight targeted collectors, five targeted foreigners, and the remaining 10 stemmed from investigations into other crimes or for unknown reasons.”

The vast majority of seized asset, eighty-one percent, were from were “recovered from collectors who, in some cases, acquired them before the law came into force and did not return them to the State. The remaining 12% (503) were in the hands of merchants. Only 259 were owned by foreigners or Costa Ricans under investigation for other reasons.”[19]

The largest seizure in the history of Costa Rica was of 3,192 objects from the Dada-Fumero family, specifically from the aunt of then director of the National Museum, Patricia Fumero. The case was closed in 2013 and the defendant acquitted. Her lawyer claimed that the museum was well aware of the collection, although the museum had no official record of it. in 2011, the case against the museum director had also been dismissed.[20]

La Nacion’s analysis of the global sales of Costa Rican artifacts also showed that the United States represented only a tiny fraction of the international market, dwarfed by sales in France, GermanyThis leads to a complex reality: While legally, all important artifacts belong to the state, in practice there are many private collections in Costa Rica, a number holding significant assemblages of pre-Columbian art, inherited or obtained decades ago. The government’s stance has been to encourage these owners to either donate the pieces to museums or at least register them and not sell them. Such collections, which must have a permit to be sold inside Costa Rica, are the most likely sources for ‘illicit’ exports today, rather than recent looting. However, enforcement has been uneven, and powerful individuals, whether collectors or sellers, face little scrutiny. Although few cases have made it to court, the threat of 1–5 year imprisonment is intended as a key deterrent. Public education initiatives, like the National Museum’s “Denuncie” (Denounce) campaign, rely on citizens to report illegal digging or selling.[21] The notion is that with the legal framework in place, success hinges on public buy-in and generating support by police and judges.

Repatriation

Under its laws and international agreements, Costa Rica pursues repatriation of artifacts – but haphazardly, and the impetus is coming primarily from foreign owners, not the Costa Rican government. Since 1986, Costa Rica has repatriated about 3,650 archaeological objects from abroad (primarily from the U.S. and Europe).[22] Many were voluntarily surrendered by collectors once they learned of the law. The largest number of returns of Costa Rican artifacts were the 1350 objects returned voluntarily by the Brooklyn Museum, as noted above.[23]

Illustration, A ride across a continent: a personal narrative of wanderings through Nicaragua and Costa Rica, Author Frederick Boyle, 1868
London, R. Bentleym, Robarts – University of Toronto.

In March 2023, a significant batch of 395 pre-Columbian artifacts that had been held at Costa Rican consulates in the U.S. (Los Angeles, Miami, Washington) was finally shipped back to San José.[24] These items – jade jewelry, ceramic sculptures, stone spheres, etc. – had been accumulating for a decade but the embassy had never bothered to send them back to Costa Rica. Finally, they were returned when the U.S. Department of State paid for the costs of packing and shipping them.  According to the Museo Nacional de Costa Rica, “the majority were surrendered voluntarily, while others were confiscated by U.S. authorities.”[25]

In September 2023, U.S. Customs and Border Protection formally repatriated three Pre-Columbian artifacts to Costa Rica – these were seized from a passenger arriving from San José in 2017 without documentation.[26] The artifacts (a tripod pottery bowl, a rattle, and a ceramic decorative fragment from 300 B.C.–A.D. 800) were identified by Costa Rica’s National Museum and claimed as state property under its patrimony law, and thus were returned.

In one recent case, in early 2025, Italian authorities seized two small pre-Columbian objects – a clay whistle and a double pottery vessel – that had been illicitly removed from Costa Rica, and delivered them to the Costa Rican Embassy in Rome for return to Costa Rica.[27]

Costa Rica’s laws also allow for domestic prosecution of looters and traffickers. Recently, the Museo Nacional de Costa Rica has created an attractive website largely focused on Costa Rica’s ancient and colonial heritage. It displays photos of conservation activities and a video showing interdicted looted materials, encouraging the public to denounce anyone trading in antiquities and celebrating the repatriation of artifacts from overseas. The museum exhibits 40 large stone sculptures but the main ancient section is closed, according to the website, and its archaeological database is not open to the public.[28]

Broader Policy Concerns

Beyond the legal technicalities, renewing the MOU with Costa Rica in the current circumstances raises broader policy concerns. These include issues of fairness, transparency, and the unintended consequences for cultural understanding:

  • Fairness to Collectors and Museums: Extending import restrictions without proper justification would unfairly punish lawful collectors, educational institutions, and museums in the United States. Many artifacts from Costa Rica have been part of private and museum collections for decades, obtained in good faith. Blanket import bans and aggressive enforcement cast a cloud over even legally acquired objects, diminishing their value and making loans or future acquisitions difficult. Such measures “unfairly penalize American collectors, researchers, and institutions” while failing to actually stop illicit digging.[29]
  • Transparency and Accountability: The process by which MOUs are requested and renewed has long been criticized for its lack of transparency. The public and stakeholders are given minimal information about the factual basis of a country’s request. Notably, Costa Rica’s request for this MOU renewal (and any evidence of looting it provided) has not been made public, leaving commentators to speculate about the true need for U.S. action.[30] The State Department’s decision-making and CPAC’s deliberations mostly occur behind closed doors, with no public accounting of how the CPIA’s criteria are being applied. Like every other recent five-year renewal – which by law must be evaluated under the same criteria as new agreements – this Costa Rican renewal request comes without any published review showing whether the MOU’s “self-help” measures or other conditions have been effective. This opacity undermines confidence that decisions are being made objectively and in accordance with the law. CPAC should demand greater transparency from Costa Rica and the State Department, including concrete, verifiable evidence of current looting and an honest assessment of Costa Rica’s efforts, before recommending any extension. Without such transparency and accountability, continuing the restrictions would be procedurally improper and contrary to the public interest.
  • Impact on Academic Research and Cultural Exchange: Overly broad import restrictions can have a chilling effect on scholarship, education, and cross-cultural exchange. When virtually all archaeological material from an entire country is placed off-limits, the result can be fewer opportunities for study, exhibition, and collaboration. American universities, researchers, and museums may struggle to import even minor artifacts for study or to borrow items for exhibition, due to fears of seizure or bureaucratic hurdles. As art-market experts have observed, sweeping restrictions “impede legitimate collecting and scholarship, depriving academics and the public of access to vital elements of cultural heritage.”[31] This runs directly counter to Congress’s admonition that restrictions “be consistent with the general interest of the international exchange of cultural property.”[32] A better policy solution would emphasize balanced measures – protecting sites and context while promoting, not preventing, academic and cultural access to Costa Rica’s heritage.

Congressional Intent and Statutory Compliance

The American Museum journal, c1900-(1918), American Museum of Natural History.

Granting or extending import restrictions in the absence of the CPIA’s required findings would violate not only the letter of the law but also the clear intent of Congress. When enacting the CPIA in 1983, Congress rejected a broad-brush approach that would honor foreign patrimony claims without question. The CPIA was therefore designed as a limited, compromise solution: it authorizes selective import controls only under stringent conditions, and only on specific types of material truly at risk. The intent was to target emergency situations of ongoing pillage, not to embargo all artifacts of a given country indefinitely.

If CPAC recommends renewing the Costa Rica MOU despite the lack of current-looting evidence and other unmet criteria, it would be effectively flouting the constraints Congress built into the law. To do so not only undermines the rule of law but also risks turning CPAC’s function into a rubber stamp for foreign requests, contrary to Congressional intent. CPAC is charged with independently evaluating whether statutory criteria are met – if they are not, the correct course is to decline the request or demand adjustments, rather than to acquiesce. Upholding the integrity of the CPIA is critical. The law represents Congress’s judgment on how best to balance cultural preservation with lawful exchange, and that judgment must be respected. Any extension of the Costa Rica agreement without full compliance with the CPIA’s thresholds would be a serious step away from the framework Congress established.

Conclusion and Recommendation

In conclusion, the proposed renewal of U.S. import restrictions on Costa Rican cultural property fails to satisfy the CPIA’s core requirements and runs counter to sound cultural policy. There is no evidence of anything but casual looting in Costa Rica today –  merely citing historical plundering is legally insufficient. Costa Rica’s government has not demonstrated that it is doing everything feasible to protect its own heritage domestically, nor that it truly needs U.S. import restrictions as a last resort. The sweeping scope of the MOU does not appear narrowly tailored to the CPIA’s definitions, and no concerted international effort parallels the U.S.’s action. Renewing the MOU under these conditions would ignore the standards set by Congress and harm the interests of collectors, museums, and researchers, all without guaranteed benefit to Costa Rica’s patrimony.

Therefore, the Committee for Cultural Policy and Global Heritage Alliance respectfully urge CPAC to recommend against renewing the MOU with Costa Rica. The Committee should decline to endorse any extension unless and until Costa Rica provides substantial, concrete evidence of current looting and undertakes verifiable self-help measures to combat it. Only with such evidence and good-faith efforts in hand could the strict legal benchmarks of the CPIA be met and a renewal be justified. Approving restrictions in the absence of those benchmarks would erode the credibility of the CPIA process and violate the intent of Congress in establishing a limited, carefully conditioned mechanism for cultural property protection. For the preservation of law, fairness, and cultural exchange, the United States must not continue or expand import restrictions on Costa Rican artifacts without meeting the CPIA’s high standards. We urge the Committee to uphold those standards by recommending no renewal at this time.

Thank you for your consideration of these comments in your deliberation. The goal of protecting Costa Rica’s heritage is best served by adhering to the CPIA’s requirements and encouraging Costa Rica to take proactive steps at home, rather than by imposing unwarranted restrictions that do not address a current threat. we appreciate the opportunity to provide input on this important decision.

Costa Rican Cultural Property Laws

Costa Rica has a long-standing legal framework for the protection of its cultural heritage, based on several key laws:

  • Law No. 14 of 1923 (repealed)
  • Law No. 7 of 1938 – Governs ownership and use of archaeological relics.
  • Law No. 6703 of 1981 – Law on National Archaeological Property.
  • Law No. 7555 of 1995 – Law on Historic/Architectural Heritage.
  • Decree No. 19016-C of 1989 – Regulation on the National Archaeological Commission.
  • Decree No. 28174 of 1999 – Regulation on requirements and procedures for archaeological studies.

Costa Rican law recognizes several categories of cultural property:

  • National Archaeological Property: All movable and immovable objects made by indigenous cultures prior to or during early Hispanic presence, including human remains and associated flora/fauna (Law 6703, Art. 1).
  • Historic/Architectural Heritage: Immovable property with cultural or historical significance (Law 7555, Arts. 2 & 6).
  • Archaeological Sites: Locations with pre-Columbian cultural remains, whether officially declared or not (Decree 28174, Art. 2).
    • Important Sites: Contain identifiable cultural or architectural structures.
    • Unimportant Sites: Lack archaeological relevance or are severely degraded.

Export

  • Absolute Ban on Export: Export of archaeological objects by individuals or institutions is prohibited, unless authorized by the National Museum and approved by the National Archaeological Commission (Law 6703, Art. 8; Law 7, Art. 4).
  • Enforcement: Customs, police, and administrative officials may inspect and seize unauthorized exports; violations carry prison sentences of 1–4 years (Law 6703, Arts. 27, 31).

Ownership Rights and Restrictions

  • State Ownership: All archaeological objects discovered after 1938 or not properly registered under prior law are property of the state (Law 6703, Art. 3; Law 7, Art. 1).
  • Custody by Individuals: Private ownership is allowed only for objects acquired before the law’s effective dates and registered accordingly. These objects must be preserved and are subject to seizure if not properly reported (Law 6703, Arts. 5, 6, 17).
  • Transfer Limitations:
    • Transfers must be reported to the National Museum.
    • Heirs may hold objects for 30 years under strict conditions (Law 6703, Arts. 7, 8; Law 7, Arts. 5–6).
    • The State has a right of first refusal on Colonial period objects (Decree 14 of 1938, Art. 16).
  • Under Law No. 6703 of 1981 (Art. 5), private individuals may retain custody (not ownership) of archaeological objects if they acquired them prior to the law’s effective date.
  • Ownership of all archaeological objects discovered after the enactment of Law No. 7 of 1938 automatically belongs to the State (Law 6703, Art. 3; Law 7, Art. 1).
  • Collectors were required to submit a sworn inventory of their collections to the Public Registry of National Archaeological Property within six months of the law’s entry into force (Law 6703, Art. 6).
  • Any object not registered during that time becomes property of the National Museum (Law 6703, Art. 17).
  • Even for legally held objects, the law does not recognize private ownership; collectors are merely custodians (bailees).
  • Custodians must preserve and care for the object. If the object is lost, damaged, or sold without compliance, the collector may lose custody and face penalties (Law 6703, Art. 2).
  • Commercial trade of archaeological objects is prohibited (Law 6703, Art. 8).
  • If the National Museum requests an object for public exhibition, and the bailee refuses, the object becomes property of the Museum (Law 6703, Art. 9).
  • In specific cases (e.g., Colonial period objects), a private holder may declare a sale or donation to the Museum, which has the right of first refusal at a fair price (Law 7, Arts. 5–6; Decree 14 of 1938, Art. 16).
  • All discoveries of archaeological objects—even on private property—must be immediately reported to authorities and handed over to the National Museum for evaluation and registration (Law 6703, Art. 11).

Thus, Costa Rican law allows very limited and regulated private custodianship of archaeological objects. These are tightly tied to historical acquisition dates, mandatory registration, and ongoing obligations to the State. In effect, collectors are temporary stewards, not owners, and they must fully cooperate with national cultural authorities or forfeit their rights.
