In my latest ethics column for The Bencher, the national publication of the American Inns of Court, I highlighted a recent decision by a federal district court in which a law firm was disqualified based on its representation of two adverse subsidiaries of a parent company. The court’s useful application of Rule 1.7 and Rule 1.9 should be of interest to those engaged in corporate and commercial litigation for subsidiaries of large companies, whether in Delaware or elsewhere.
