U.S. Steel’s failure to provide a copy of a letter sent to a special master to the Equal Employment Opportunity Commission, which has been engaged in a “lengthy and more than contentious” dispute with the employer, does not render void that master’s recommendations, a federal district judge of the Western District of Pennsylvania has ruled.

The letter was written by U.S. Steel Corp. during a case brought by the EEOC over alleged violations of the Americans With Disabilities Act, U.S. District Judge Nora Barry Fischer said in EEOC v. U.S. Steel. But Fischer said the letter was not an instance of ex parte communication.
