Supreme Court: But-for Causation Test Applies to Employees Alleging Title VII Retaliation, Not the Lessened Causation Test | Practical Law
In University of Texas Southwestern Medical Center v. Nassar, the US Supreme Court held in a 5 to 4 decision that an employee alleging Title VII of the Civil Rights Act of 1964 (Title VII) retaliation must prove that a retaliatory motive on the part of his employer was the but-for cause of the negative employment action and not just a motivating factor under the lessened causation test.
