A Pittsburgh law firm has been disqualified from representing a company suing a former employee for allegedly violating a noncompete because that law firm represented the employee and company in a similar challenge when he joined years prior.

U.S. District Judge Mark A. Kearney of the Eastern District of Pennsylvania, who was presiding over the Western District case, disqualified Metz Lewis Brodman Must O’Keefe from representing Cool Pair Plus in its bid to stop former employee Sean Mykleby from working for Thermomagnetics & Cryogens Inc.
