What is the effect of a failure to enter and enter findings of fact and conclusions of law?

Appellant asserts prejudice because the court did not make and enter findings of fact and conclusions of law, claiming that the judgment may not stand without the support of one or the other. Respecting the failure to make findings where the opinion of the trial court is before us, see Hazeltine Corporation v. General Motors Corporation, 3 Cir., 131 F.2d 34, 37. The opinion here provides a clear understanding of the basis of the decision below, and the absence of findings of fact and conclusions of law is not sufficient to justify a reversal in this case.
