Pan American Computer Corporation (PACC) appeals from the district court's dissolution of an injunction pendente lite it had previously issued under 10 L.P.R.A. § 278b-11 prohibiting Data General Corporation (DGC) from terminating a dealership contract under which PACC distributed and serviced DGC products in Puerto Rico. The district court had originally entered the injunction, as authorized by statute, after considering "the interests of all parties concerned and the purposes of the public policy contained in this chapter." The court properly did not make formal findings on the usual preliminary injunction criteria of irreparable harm and probability of success on the merits, see DeMoss v. Kelly Services, Inc., 493 F.2d 1012, 1015 (1st Cir. 1974), although its factual findings made at that time suggest a tentative view that PACC had up to then substantially performed its obligations under the dealership contract, and that the balance of hardship weighed in PACC's favor. The court dissolved the injunction some 18 months later upon its finding, reached after an evidentiary hearing, that PACC had assigned its maintenance duties, along with related rights, to ITT Diversified Services, Inc., in violation of an essential condition of the dealership agreement and to the substantial detriment of DGC's interests. The court held that this action by PACC gave DGC just cause to terminate the agreement. The court took the view that PACC's action rendered the circumstances so different that the statutory considerations now weighed against retaining the injunction in force.

PACC contends on appeal that the court erred in finding an assignment in violation of the contract; in concluding that such a violation, even if committed, would constitute just cause for termination; and in ruling that just cause, even if present, would warrant vacating the injunction. We find no merit in any of these contentions, and we affirm the judgment of the district court.

The contract between PACC and ITT, along with the evidence of the parties' conduct in implementing it, supports the court's conclusion that PACC had not merely delegated a sub-agent, as the agreement authorized, but had assigned rights and duties, in violation of the agreement. Further, the evidence supports the court's finding that PACC's maintenance duty was an "essential obligation" under the agreement, and that assignment of that duty in violation of the agreement constituted nonperformance of it, giving rise to just cause for termination under the statute. The evidence also showed that the assignment to ITT "substantially affects" DGC's interests since ITT is a "known service competitor of DGC throughout the world";2 thus the assignment established just cause for termination on the second statutory ground as well as the first.

Having found just cause to terminate, in contrast to its previous implicit finding of substantial performance by PACC, the court was well within its discretion to reconsider the propriety of the injunction. While the statute does not require a finding of likelihood of success as a prerequisite to issuance of an injunction, the court's view of the merits would certainly affect its judgment of the weight of the parties' interests and of the injunction's effect on the statutory policies. The court properly noted also that, after requesting and receiving an order that DGC maintain the status quo, PACC had itself made a substantial change in the relationship between the parties, in violation of the spirit if not the letter of the injunction.3 Considering these factors, the court properly could and implicitly did conclude that the injunction no longer served its purposes and that the hardship it imposed on DGC had risen to an unjustified level.
