P.R. Laws tit. 27, § 1270
The review shall be on the basis of the administrative record of the proceeding before the Commission and certified by the Secretary thereof. Should any of the parties convince the court that new evidence has been discovered, after the hearing before the Commission, which could not have been obtained by the exercise of reasonable diligence, for use in said hearing, and which will materially affect the merits of the case, the court may return the evidence and record to the Commission for the receipt of the subsequent evidence discovered. The Commission may modify its findings of fact as a result of the additional evidence thus introduced, and shall file with the court the new or modified findings, which, if supported by substantial evidence, shall be conclusive, as well as its recommendation, if any, for the modification of or to render ineffective the original decision. Judgments rendered by the Court of First Instance in these cases shall be reviewable by the Supreme Court of Puerto Rico.
