The Puerto Rico Court of Appeals recently upheld a lower court's decision in a case involving a dispute over the installation of a generator on a boat. The court ruled that the contractor, Carlos Alegría, fulfilled his obligations under the contract, and the plaintiff, Silverio Pérez Martínez, did not prove his claims of negligence or damages. This ruling, issued on April 30, 2026, affects both parties and clarifies legal standards in contract disputes related to service installations.

The case began when Pérez Martínez filed a lawsuit against Alegría in February 2021, claiming that the installation of an electrical generator on his boat was done improperly. He alleged that after paying $20,000 for the generator and its installation, the equipment failed to function correctly, leading to a loss of warranty and additional damages. Pérez Martínez sought the cancellation of the contract, a refund of his payment, and compensation for damages totaling $60,000.

In response, AlegrĂ­a argued that he had only been hired for specific tasks related to the generator's installation and that the plaintiff was responsible for subsequent maintenance. The case went through various legal proceedings, including a counterclaim from AlegrĂ­a for damages to his reputation due to the lawsuit. The lower court eventually ruled in favor of AlegrĂ­a, stating that he had completed the installation correctly and that the plaintiff had not demonstrated any negligence on his part.

The Court of Appeals, led by Judge Campos Pérez and joined by Judges Candelaria Rosa, Adames Soto, and Trigo Ferraiuoli, reviewed the case and confirmed the lower court's ruling. The court noted that the plaintiff had not provided sufficient evidence to support his claims. It stated, “the plaintiff navigated for around eight months, traveled to the Dominican Republic, and returned to Puerto Rico without encountering issues with the generator.” The court concluded that Pérez Martínez failed to prove that the generator's installation was negligent or that Alegría was responsible for the generator's malfunction.

This ruling reinforces the principle that parties involved in contract disputes must provide clear evidence to support their claims. It highlights the importance of demonstrating negligence or breach of contract in service-related cases. The court emphasized the credibility of the expert testimony presented by Alegría, which played a significant role in the decision. The court found that the evidence presented by Pérez Martínez did not sufficiently undermine the credibility of Alegría's expert.

The impact of this ruling extends beyond the immediate parties involved. It sets a precedent for how courts may evaluate similar contract disputes in the future, particularly those involving service installations and the burden of proof required from plaintiffs. This case underscores the necessity for plaintiffs to present compelling evidence to support their claims in civil litigation.

Looking ahead, it is unclear whether Pérez Martínez will seek further legal recourse. The court's ruling can potentially be appealed to a higher court, but details about any such plans were not available in the court filing. As of now, the case stands as a significant example of the complexities involved in contractual agreements and the expectations of service providers.
