The Pennsylvania Supreme Court has agreed to hear arguments in a case looking into what is a mandatory prerequisite for proving that an insurance carrier acted in bad faith, and what is merely a factor for consideration.

The justices granted review in Rancosky v. Washington National Insurance Company Tuesday, on the specific issue of whether the requirements for establishing bad faith outlined in a 1994 case remain good law, and, if so, whether a finding that the carrier acted out of “self-interest or ill will” is a discretionary consideration, or a mandatory element for proving bad faith.
