Univ. of Texas Southwestern Medical Center v. Nassar, 570 U.S. 338 (2013)
The Texas university medical center has an agreement with Parkland Memorial Hospital, requiring the Hospital to offer vacant staff physician posts to University faculty members. A physician of Middle Eastern descent, both a University faculty member and a Hospital staff physician, claimed that Levine, one of his University supervisors, was biased against him because of his religion and ethnic heritage. He complained to Fitz, Levine’s super¬visor. He wanted to continue working at the Hospital without also being on the University faculty. He resigned his teaching post and sent a letter to Fitz and others, stating that he was leaving because of Levine’s harassment. Fitz, wanting public exoneration for Levine, objected to the Hospital’s job offer, which was then withdrawn. The doctor sued, claiming that Levine’s harassment resulted in his constructive discharge from the University, in violation of 42 U.S.C. 2000e–2(a), and that Fitz’s efforts to prevent his hiring were in retaliation for complaining about that harassment, in violation of section 2000e–3(a). A jury agreed on both claims. The Fifth Circuit vacated as to the constructive-discharge claim, but affirmed with respect to retaliation, reasoning that retaliation claims under 2000e–3(a) require only a showing that retaliation was a motivating factor for the adverse employment action, not its but-for cause. The Supreme Court vacated and remanded. Title VII retaliation claims must be proved according to traditional principles of but-for causation, not the lessened causation test stated in section 2000e–2(m). Title VII’s anti-retaliation provision appears in a different section from its status-based discrimination ban and uses the term “because,” indicating that retaliation claims require proof that desire to retaliate was the but-for cause of the challenged employment action. The Court noted that retaliation claims are made with “ever¬increasing frequency” and that lessening the standard could contribute to the filing of frivolous claims.
