Cleland B. Welton II

Cleland Welton is counsel in Mayer Brown’s Supreme Court & Appellate practice, resident in the New York office. Cleland is an experienced litigator focused on briefing and argument in appellate courts across the United States, including the US Supreme Court. Cleland has briefed dozens of federal and state appeals covering subject-matter areas as diverse as patent law, contracts, insurance, arbitration, business torts, federal procedure, and administrative law. Cleland’s practice also includes developing trial strategy as well as briefing critical and legally intensive issues in trial courts and before arbitration tribunals.

As lead counsel, Cleland has briefed and argued cases before the Second, Eighth, and DC Circuits, and has successfully represented clients on appeal, in federal district court, and in administrative proceedings. Most recently in Gomez v. Trump, he won a preliminary injunction and then summary judgment on claims that the Trump Administration had illegally ceased processing “diversity” visa applications during the pandemic. These victories cleared the way for more than 16,000 immigrants from around the world to receive visas and become lawful permanent US residents; without our litigation, these immigrants’ visa eligibility would have permanently expired. Gomez was named Mayer Brown’s 2021 North America pro bono matter of the year.

Prior to joining Mayer Brown, Cleland was a member of the appellate practice in the New York office of another prominent international law firm. He previously served as a law clerk to the Hon. D. Brooks Smith of the US Court of Appeals for the Third Circuit, and to the Hon. Charles R. Simpson III of the US District Court for the Western District of Kentucky.
