A federal judge in Pennsylvania has certified a class in a lawsuit alleging a nationwide call center company violated the Telephone Consumer Protection Act of 1991.

In a Feb. 24 opinion, U.S. District Judge Gerald McHugh of the Eastern District of Pennsylvania granted plaintiff Janine Williams’s motion for class certification in a case against Pisa Group, after finding Williams had proven by a preponderance of the evidence that the prerequisites of Rule 23(a) and Rule 23(b)(3) were met.
