When the state Supreme Court issued its ruling in Tincher v. Omega Flex nearly 10 years ago, many Pennsylvania attorneys said the ruling represented a tidal shift in how products liability cases would be tried.

But, in a ruling that may show the limits of Tincher‘s scope, the high court has determined that defendants still cannot introduce evidence showing their product complies with industry standards, finding that the 2014 ruling did not change the way courts must handle such evidence.
