Hazen Paper Co. v. Biggins

Hazen Paper Co. v. Biggins, 507 U.S. 604 (1993), was a United States Supreme Court case in which the court held that a disparate treatment claim cannot succeed unless the employee's protected trait had a determinative influence on the employer's decisionmaking.

Background
Hazen Paper fired Biggins, 62, a few weeks before his service would have reached the required number of years for his pension to vest. Biggins sued Hazen Paper alleging a violation of the Age Discrimination in Employment Act of 1967.
