The Court of Appeals of Puerto Rico recently ruled against COBRA Acquisitions LLC in a case involving disputes over construction taxes owed to municipalities. The court's decision affects COBRA's ability to amend its lawsuit against the Municipality of Las Piedras and the Municipality of Caguas, which claimed that COBRA owed significant amounts in construction taxes. This ruling is significant as it clarifies the procedural requirements for amending lawsuits and the jurisdictional issues surrounding municipal tax claims.

COBRA Acquisitions LLC, a contractor involved in the reconstruction of Puerto Rico's electrical infrastructure after the devastation caused by hurricanes Irma and Maria, filed lawsuits against two municipalities in Puerto Rico. The disputes arose over claims that COBRA owed construction taxes for work performed under contracts with the Puerto Rico Electric Power Authority (AEE). The municipalities argued that COBRA was legally required to pay these taxes, while COBRA contended that it was exempt from such payments due to its contractual relationship with AEE.

The case originated on February 20, 2020, when COBRA filed a declaratory judgment and tax collection lawsuit against the Municipality of Las Piedras and the Puerto Rico Electric Power Authority. COBRA claimed that the municipality lacked the authority to impose construction taxes on it, as it was a contractor for AEE, which had an exemption from such taxes. The legal battle continued as COBRA sought to amend its complaint and conduct discovery related to the tax assessments made by the municipalities.

In April 2026, the First Instance Court denied COBRA's requests to amend its complaint and continue discovery on specific aspects of the tax assessments. COBRA's attempts to amend the lawsuit were met with opposition from the municipalities, which argued that the amendments were untimely and prejudicial. The municipalities asserted that allowing the amendments would effectively restart the litigation process after years of proceedings.

The Court of Appeals, consisting of Judges Cintrón Cintrón, Rodríguez Flores, and Díaz Rivera, reviewed COBRA's petitions for certiorari regarding the First Instance Court's decisions. The court ultimately denied COBRA's requests, stating that the proposed amendments did not introduce new facts or legal theories that would justify altering the course of the litigation. The court emphasized that the First Instance Court acted within its discretion in denying the amendments.

The court ruled, "The proposed amendment does not introduce new facts, nor does it alter the nature of the case, nor does it cause undue prejudice to the Municipality."

In its ruling, the court underscored the importance of adhering to procedural rules regarding amendments and the necessity of timely presenting claims. The court noted that COBRA had previously engaged in administrative hearings where it could have raised its claims but failed to do so. This failure contributed to the court's decision to deny the amendments.

The impact of this ruling is significant for COBRA and potentially other contractors facing similar tax disputes with municipalities. The decision reinforces the need for parties to comply with procedural requirements and highlights the importance of timely addressing jurisdictional issues in tax-related litigation. The ruling may deter other contractors from delaying their claims or seeking amendments late in the litigation process, as it establishes a precedent for strict adherence to procedural timelines.

Moving forward, COBRA has limited options for appealing this ruling. The court's decision may be subject to further review, but the chances of success in overturning the ruling appear slim given the court's clear reasoning. There are no related cases pending that could directly affect this ruling, but the implications of this case may resonate in future tax disputes involving contractors and municipalities in Puerto Rico.
