Citing a lack of evidence and recent limits on punitive damages, a court of appeal panel filleted an $18.5 million award in a psychiatric disability case against McKesson Corp. and a supervisor on Tuesday.

The appeals court halved the compensatory award, and said that the jury’s $15 million award of punitive damages had to be reduced to about $2 million, saying that was about as much as the U.S. Constitution will allow under recent precedents.
