Las Marías Reference Laboratory Corp. v. Municipio de San Juan

**What Happened** Las Marías Reference Laboratory sued the Municipality of San Juan for breach of contract, claiming the city owed them money for services they had provided. The laboratory argued they had a valid contract with the municipality and should be paid for their work. **What the Court Decided** The Puerto Rico Supreme Court ruled against the laboratory and in favor of the Municipality of San Juan. The court found that municipal contracts must be submitted to the Comptroller's Office to be valid and enforceable. Since this contract was never submitted to the Comptroller's Office, the court declared it void and unenforceable. This meant the laboratory could not collect payment, even though they may have performed the work. **Why This Matters for Workers** This ruling is important for workers and businesses that contract with Puerto Rican municipalities. It establishes that proper government approval procedures must be followed for municipal contracts to be legally binding. Workers should verify that any contracts with municipalities have gone through required approval processes before beginning work, as they may not be able to collect payment if proper procedures weren't followed, regardless of whether they completed the services.
