In a suit brought under a Puerto Rico 'Law 458', which prohibits government instrumentalities and public corporations from awarding bids or contracts to persons (including juridical persons) who have been convicted of 'crimes that constitute fraud, embezzlement or misappropriation of public funds listed in section 928b of this title,' P.R. Laws Ann. tit. 3, section 928, the district court's judgment remanding the case to the Commonwealth Puerto Rico Court of First Instance is affirmed where the forum selection clauses at issue were enforceable, and that the unanimity requirement of 28 U.S.C. section 1446(b)(2)(A) therefore could not be satisfied.
