A Fulton County judge isn’t saying she was wrong when she forbade the Philadelphia-based mega-firm Duane Morris from representing a subsidiary of McKesson Corp. in an Atlanta intellectual property dispute. But, citing changed circumstances, she’s lifted her ban on the firm’s involvement in the case.

In a November order, Fulton County Superior Court Judge Thelma Wyatt Cummings Moore ruled that Duane Morris violated conflict of interest rules by representing subsidiaries of McKesson Corp in a Pennsylvania bankruptcy while representing a couple who brought an action against an unrelated McKesson subsidiary.
