Following the remand directed by our opinion in the former appeal of this matter, Lewis v. Spencer et al., 5 Cir. 1972, 468 F.2d 553, the district court held an evidentiary hearing and entered its opinion order1 finding adversely to the plaintiff-appellant’s contentions as to the factual issues directed to be fried by our remand. Those issues were (1) whether or not the action2 of the Board of Regents of San Jacinto Junior College in not renewing Ms. Lewis’ teaching contract was taken in retaliation for her exercise of First Amendment rights and her rights of freedom of association; and (2) whether the adoption of the policy without a recognition therein of plaintiff and her husband’s unique situation (viz, recently married and the only couple in the school to whom the policy was applicable) through such a device as a grandfather clause or prospective application, would make impermissible as applied an otherwise constitutionally valid policy.

The trial court’s hearing fully ventilated these issues and his findings of fact settled them, unless we determine that his findings were “clearly erroneous”. Rule 52(a), F.R.Civ.P.; United States v. National Association of Real Estate Boards, 1950, 339 U.S. 485, 495-496, 70 S.Ct. 711, 94 L.Ed. 1007. The task of demonstrating that the findings of a trial court are “clearly erroneous” is a heavy burden indeed. We are satisfied that the plaintiff-appellant has not met that burden on this appeal. Our view is rather that the trial court’s findings were required by the evidence *95presented, to the extent that we would seriously consider assigning a “clearly erroneous” label if contrary findings had been reached.

Affirmed.
