Cozen O’Connor is still on the hook for the actions of one of its former lawyers while he was employed at the firm, but a federal judge has ruled that the firm can’t be held liable for the lawyer’s conduct after he moved to Blank Rome.

In an opinion filed Tuesday afternoon, U.S. District Senior Judge Jan DuBois of the Eastern District of Pennsylvania granted Cozen O’Connor’s motion for summary judgment with respect to disbarred lawyer Charles Naselsky’s actions while he was not employed at Cozen O’Connor. The judge otherwise denied summary judgment.
