The Puerto Rico Court of Appeals recently ruled in favor of Engineering Services International, Inc. (ESI) in a case involving a disputed engineering contract with the Autoridad de EnergĂa ElĂ©ctrica (AEE). The court's decision, issued on May 21, 2026, overturned a previous ruling that had declared the contract null and ordered ESI to return over $4 million in payments. This ruling is significant as it impacts how engineering contracts are interpreted and enforced in Puerto Rico.
The case began when ESI entered into a contract with AEE for the design and construction of a water treatment system at the San Juan Steam Plant. Disagreements arose regarding the installation of water pumps, leading ESI to seek a declaratory judgment to clarify its obligations under the contract. After a series of legal proceedings, the lower court ruled that ESI's contract was invalid because it was not a licensed professional corporation at the time of signing, thus violating Puerto Rican law.
Engineering Services International, Inc. is a company that provides engineering services, while the Autoridad de EnergĂa ElĂ©ctrica is a public corporation responsible for electricity generation and distribution in Puerto Rico. The dispute centered on whether ESI had the legal capacity to enter into the contract for engineering services, given that it was initially registered as a regular corporation rather than a professional corporation.
The case reached the Court of Appeals after ESI appealed the lower court's decision, which had found the contract null and ordered the return of all payments made to ESI under the agreement. The lower court argued that ESI's lack of proper licensing rendered the contract void from the beginning, a position that ESI contested.
In its ruling, the Court of Appeals found that the lower court erred in declaring the contract null. The judges noted, “the contract constitutes one for the illegal practice of engineering by ESI and, therefore, is null ab initio.” However, they also stated that ESI could legally provide services through licensed professionals. The court emphasized that ESI's actions did not violate the law as it had employed licensed engineers to fulfill its contractual obligations.
The panel of judges, including President Judge DomĂnguez Irizarry, Judge Cruz Hiraldo, and Judge Sánchez Báez, concluded that the contract should not have been entirely voided. They pointed out that ESI had acted through licensed agents and employees, which allowed it to legally provide the services outlined in the contract.
This ruling has significant implications for future contracts in Puerto Rico, particularly in the engineering sector. It clarifies that corporations can offer professional services through licensed individuals, even if the corporation itself is not a professional entity at the time of contracting. This could potentially open the door for other companies facing similar challenges regarding their contractual agreements.
The Court of Appeals' decision also reinforces the importance of adhering to legal standards when it comes to public funds and contracts. The ruling highlights that while contracts must comply with statutory requirements, the presence of licensed professionals within a corporation can mitigate issues of legality.
Moving forward, this case may set a precedent for how courts interpret the legality of contracts involving professional services in Puerto Rico. It may encourage companies to seek clarity on their legal standing before entering contracts, knowing that the presence of licensed professionals can validate their agreements.
As for what’s next, the case has been sent back to the lower court for further proceedings, allowing ESI to continue its claims against AEE. There is no indication that this ruling will be appealed further, but it may influence other ongoing or future cases involving similar contractual disputes.
