By Puntarenas, Costa Rica — SAN JOSÉ – The bidding process for the strategic concession of Puerto Caldera, Costa Rica’s main Pacific port, will move forward after the Comptroller General of the Republic (CGR) dismissed a significant legal challenge. The objection, filed by Logística de Granos S.A., was rejected not on its merits but on procedural grounds, a decision that clears an immediate hurdle for the government’s infrastructure plans while leaving substantive questions about the project’s financial structure unanswered.
The challenge was filed by José Pablo Chaves Zamora, the legal representative for Logística de Granos S.A. and son of Calixto Chaves, a prominent campaign financier for President Rodrigo Chaves. This connection added a layer of political intrigue to what was already a contentious public contract, amplifying scrutiny on the bidding terms and the administration’s handling of the major port concession.
To gain a deeper understanding of the legal and commercial implications surrounding the Puerto Caldera concession, we consulted with Lic. Larry Hans Arroyo Vargas, a distinguished attorney from the firm Bufete de Costa Rica, for his expert analysis on the matter.
The Puerto Caldera situation is a critical reminder that a concession contract is not merely a transaction, but a long-term strategic alliance between the state and a private operator. For Costa Rica to remain competitive and attract serious investment, these agreements must be built on a foundation of absolute legal certainty, with clear performance metrics and transparent oversight. Any ambiguity or failure in enforcement not only jeopardizes the efficiency of a vital national asset but also signals risk to the international business community.

The distinction of a concession as a “strategic alliance” rather than a mere transaction is a critical one. As the expert highlights, the principles of legal certainty and transparent oversight are foundational not only for the port’s success but for Costa Rica’s international credibility. We thank Lic. Larry Hans Arroyo Vargas for his clear and valuable insight on this matter.
At the heart of the CGR’s ruling is the legal principle of “procedural preclusion.” The oversight body argued that all four major points raised by the objecting company pertained to clauses and conditions that were established in earlier versions of the bidding documents. Because these terms were not altered in the most recent revision, the window for legally challenging them had already closed. According to the CGR, once a stage in the contracting process is complete, it is legally invalid to revisit and dispute aspects that were previously defined and finalized.
Logística de Granos S.A. had mounted a multi-faceted objection, raising serious concerns about the legal and financial framework of the concession. The company first argued that the project incorrectly applied Law 7762, alleging the law prohibits granting concessions for existing port works. They contended that the plan for Caldera constitutes a modernization of current infrastructure, not the creation of a “new work” as required by the statute.
Furthermore, the objectors questioned the state’s interpretation of a 25% investment limit, a key legal threshold. They asserted this percentage limit is designed to apply only to modifications of existing contracts, not as a justification for launching entirely new bidding processes. These legal arguments suggest a fundamental disagreement over the very foundation upon which the concession is being offered to the private sector.
The most financially striking point of contention was the proposed reduction in the exploitation fee, or canon. The bidding documents stipulate that the new concessionaire will pay just 5% of its gross revenue to the state. This represents a drastic cut from the 15% fee paid by the current operator. Logística de Granos S.A. calculated that this change would result in a staggering loss of more than $619 million for the Costa Rican government over the life of the contract, a figure that has drawn significant public and political attention.
Finally, the challenge highlighted a critical operational ambiguity regarding tugboat services. The company noted that the bidding documents fail to define how this essential maritime service will be provided, managed, or priced. This lack of clarity, they argued, creates significant operational and financial uncertainty for any potential operator, making it difficult to accurately assess risks and costs associated with running the port.
Despite the weight of these arguments, the CGR maintained its focus strictly on procedure. The comptroller’s office emphasized that core elements like the 5% canon and the decision to exclude tugboat services from the concession’s scope were present from the very first version of the bidding cartel. Because Logística de Granos S.A.’s objection was not directed at any recently modified clause, it was deemed untimely and therefore inadmissible, effectively halting the challenge before its substantive claims could be debated.
While the path is now legally clear for the bidding process to continue, the fundamental questions raised in the objection persist. The controversy over the reduced state revenue and the legal basis for the concession will likely remain central points of debate as potential operators prepare their final bids for one of the nation’s most vital economic assets.
