Court of Appeals for the Seventh Circuit July 22, 1985, 84-3013 (Ethyl Corporation v. United Steelworkers of America, Afl-Cio-Clc and Local No. 7441, United Steelworkers of America, Afl-Cio-Clc)

POSNER, Circuit Judge.

The steelworkers union appeals from a judgment setting aside a labor arbitrator’s award. The appeal requires us once again to consider the scope of judicial review of labor arbitration awards.

In 1980 the union signed a collective bargaining contract with Ethyl Corporation to govern employment at a chemical plant in Indiana.
