Court of Appeals for the Fifth Circuit May 8, 1981, 80-3243 (Adam G. Nunez v. The Superior Oil Company)

ALVIN B. RUBIN, Circuit Judge.

The issue before us can be briefly stated: did the district judge err in directing a verdict against a mineral lessor in his suit for cancellation of a mineral lease because of a lengthy delay by the lessee in paying royalties? Its resolution, however, requires us to review in detail the four volumes of testimony and the exhibits introduced during a three-day trial.
