Allyson N. Ho is a partner in the Dallas office of Gibson, Dunn & Crutcher LLP and co-chair of the Firm’s nationwide Appellate and Constitutional Law practice group.
Mrs. Ho is widely regarded as one of the nation’s most accomplished appellate litigators. She has presented over 60 oral arguments in federal and state courts nationwide, including multiple high-stakes cases on behalf of business before the U.S. Supreme Court.
Her most significant winning arguments include a U.S. Supreme Court reversal worth billions of dollars for unionized employers in the Sixth Circuit; a U.S. Supreme Court reversal limiting the power of federal regulators; a multi-billion dollar environmental win in the Fifth Circuit; a multi-billion dollar commercial victory for the founder of a technology company in the Appellate Division of the New York Supreme Court; a billion dollar environmental win in the Houston Court of Appeals; a nine-figure commercial victory in the Corpus Christi Court of Appeals; and a nine-figure arbitration win in the Fifth Circuit.
Among her numerous accolades, Chambers has named her one of the nation’s top appellate lawyers every year for the past nine consecutive years (2012-20)—a record unmatched by (and far exceeding) any other appellate litigator in Texas. She is also routinely named as a leading appellate lawyer by Benchmark, The Best Lawyers in America®, The Legal 500, Texas Super Lawyers, and D Magazine.
