Louis Chaiten provides U.S. and overseas clients with advocacy, analysis, and advice concerning a broad range of complex litigation and prelitigation matters. In trial court litigation and domestic and international arbitration proceedings, Louis has handled disputes involving pharmaceutical and biologic products, clinical trials, commercial contracts, joint ventures, securities, corporate governance, and accounting issues. He is frequently called upon to advise clients on their most analytically difficult legal issues.

Louis is also an accomplished appellate litigator. His recent appellate victories include successfully defending an international iron ore supplier in a dispute over reclamation services, multiple financial institutions in litigation over their securitization activities, and a corporation and its directors against claims of securities fraud.

Louis commits substantial time to pro bono work. In collaboration with the New York-based Innocence Project, he successfully argued an appeal on behalf of Thomas Siller, an Ohio man convicted of murder in 2001. Recently discovered forensic evidence undermined that conviction. Mr. Siller was freed in March 2011 after more than a decade in prison.

Louis previously clerked on the U.S. Supreme Court and the U.S. Court of Appeals for the Sixth Circuit, and served in the Office of Legal Counsel at the U.S. Department of Justice, which is responsible for advising the president, the attorney general, and other executive branch officials on complex issues of constitutional, statutory, and international law.
