The Puerto Rico Court of Appeals recently ruled against COBRA Acquisitions LLC in a significant case concerning municipal construction taxes. The court denied COBRA's requests to amend its claims and continue discovery regarding tax assessments imposed by the Municipality of Caguas and the Electric Power Authority of Puerto Rico. This ruling affects contractors working with Puerto Rican municipalities and clarifies the legal boundaries of municipal tax authority.

The case, titled COBRA Acquisitions LLC v. Municipio De Caguas, Autoridad De Energía Eléctrica, Estado Libre Asociado De Puerto Rico, was filed on June 29, 2026, under docket number TA2026CE00756. The court's decision highlights the complexities of tax disputes involving public contractors and local governments.

Background

COBRA Acquisitions LLC is a contractor that entered into emergency contracts with the Electric Power Authority (AEE) to rebuild the electrical grid in Puerto Rico after hurricanes Irma and María caused extensive damage. The disputes arose when COBRA was billed for construction taxes by the municipalities where it performed work, specifically the Municipality of Caguas.

COBRA argued that it should not be subject to these taxes because it was acting as a contractor for AEE, which is exempt from such taxes under Puerto Rican law. The case began in February 2020 when COBRA filed a declaratory judgment action against the municipalities and the AEE, seeking to establish that the municipalities lacked the authority to impose construction taxes on its work.

The dispute escalated when COBRA attempted to amend its claims and requested further discovery to challenge the tax assessments. The municipalities opposed these requests, arguing that COBRA had failed to comply with procedural requirements and that the amendments would unduly delay the proceedings.

The Ruling

The Puerto Rico Court of Appeals, led by Judge Díaz Rivera, ruled against COBRA's requests on June 29, 2026. The court stated, "The petitioner's request to amend the complaint was denied as it did not introduce new facts or alter the nature of the case. The delay in seeking these amendments was deemed unacceptable given the time elapsed since the case was filed."

Furthermore, the court upheld the lower court's decision to deny COBRA's request for additional discovery, emphasizing that COBRA had not met the jurisdictional requirements to challenge the tax assessments. The court noted that COBRA's failure to pay the taxes in question limited its ability to contest the municipalities' claims.

Impact

This ruling has significant implications for contractors working with Puerto Rican municipalities. It reinforces the authority of local governments to impose taxes on construction activities and clarifies the procedural requirements contractors must follow to challenge these assessments. The decision may deter other contractors from attempting to contest municipal tax claims without first complying with the necessary legal procedures.

Additionally, the ruling sets a precedent regarding the timing and nature of amendments to legal complaints in tax-related disputes. It highlights the importance of timely and thorough compliance with procedural rules in legal proceedings, particularly in cases involving municipal taxation.

What's Next

COBRA Acquisitions has the option to appeal the court's decision to a higher court, but details regarding potential further legal action were not available in the court filing. The outcome of this case may influence similar disputes involving contractors and municipalities in Puerto Rico.
