A deaf South Florida woman who sued because she couldn’t read her mumbling manager’s lips won’t recover a $775,000 jury verdict, as the U.S. Supreme Court has declined to weigh in on her case.

It’s a lawsuit that demonstrates the limits of what steps companies must take to ensure deaf workers are treated fairly under the Americans with Disabilities Act, as U.S. District Judge William Zloch had overturned the verdict, finding “no reasonable juror” would have ruled for the plaintiff.
