Briefing
What it's about
The Supreme Court declined to hear Murray v. Mayo Clinic, which asked what a plaintiff must show to prove disability discrimination under the Americans with Disabilities Act. Because the Court did not take the case, it did not decide whether showing disability was a motivating factor is enough.
Impact
That leaves the lower-court result in place and gives workers and employers no new Supreme Court rule on ADA proof standards. For example, someone suing over a firing because of disability must still rely on the rule already used in the relevant lower court.
What's next
There is no further Supreme Court action in this docket. The same ADA question could reach the Court again in a different case.
What was Murray v. Mayo Clinic about?
The case asked whether an ADA plaintiff only needs to show disability was a motivating factor in the employer's action. The Supreme Court declined to answer that question here.
Who is affected when the Supreme Court declines review in Murray v. Mayo Clinic?
Workers bringing ADA claims and employers defending them are most affected. The lower-court rule stays in place because the Supreme Court did not step in.
What happens next after Murray v. Mayo Clinic?
This Supreme Court docket is finished. The ADA question could return only if the Court agrees to hear a future case.
