Joseph Wayland is credited by many as reversing the US Department of Justice’s antitrust division’s fortunes in civil litigation. Hired to head the civil enforcement division in 2010 and appointed as acting assistant attorney general in 2012, Wayland led the division’s first successful litigated merger challenge in nearly a decade in H&R Block, and its subsequent challenge of AT&T/T-Mobile, which ended with the parties abandoning the deal.
