Allyson N. Ho is co-chair of the Firm’s nationwide Appellate and Constitutional Law practice group and partner in the Dallas office of Gibson, Dunn & Crutcher.
She has presented over 100 oral arguments in federal and state courts nationwide, including five high-stakes business cases before the U.S. Supreme Court.
Chambers has called her “undoubtedly one of the premier appellate lawyers in the United States,” and recognized her as one of the few advocates ranked among the country’s top appellate lawyers every year for the past ten years. Benchmark has named her to its “Short List” for “Appellate Litigator of the Year.” She is one of the few appellate lawyers nationwide named to the BTI Client Service All-Stars List, recognized by corporate counsel for “delivering the absolute best in client service.”
The American Lawyer has recognized her in its “Litigators of the Week” column every year for the past four years. The National Law Journal has repeatedly featured her on its “Appellate Hot List.” Law360 has honored her as an “Appellate MVP,” “Litigation Powerhouse,” and leading member of the “Employment Group of the Year.” Texas Lawyer has recognized her as a “Distinguished Leader,” “Attorney of the Year Finalist,” leading member of a “Litigation Department of the Year,” and one of the state’s most “Winning Women.” Other profiles include “Texas Appellate Power Couple” (Texas Lawbook, Jan. 7, 2021), “Three Supreme Court Insiders From Outside the Beltway” (The National Law Journal, July 21, 2016), and “A Supreme Month: Lawyer Credits Preparedness in Ability to Argue Two U.S. High Court Cases in Three Weeks” (Texas Lawyer, Dec. 8, 2014).
Federal and State Appellate Practice
Allyson has argued landmark business cases before the U.S. Supreme Court, in the areas of bankruptcy, patents, ERISA, employment, and administrative law. The National Law Journal called her a “Veteran SCOTUS Advocate” in the “upper echelons of Supreme Court practice.” Law360 named her a “Supreme Court Star” and “one of the nation’s preeminent appellate lawyers.” And EmpiricalSCOTUS.com ranked her among “the most successful attorneys that currently practice before the Court.” She once argued two significant business cases before the Court within the span of 21 days—including a “significant ruling for employers” that “paved a new path for companies paying millions of dollars in retiree health care benefits” (Law360), and a landmark administrative law dispute in which “several justices agreed with Ho’s contention that SCOTUS should revisit and overrule its own precedent” (Law360). She prevailed against the EEOC in a case that the employment defense bar called “good news for employers across the country.” And in “the most important patent case in modern history” according to patent law experts, her argument before the Court was credited for “pick[ing] up two votes that pundits thought unreachable.”
She has appeared before every federal court of appeals in the country, including en banc arguments before the Fourth and Sixth Circuits. She has successfully represented businesses in every federal circuit nationwide.
She also regularly represents businesses in state appellate courts across the country, including the Texas Supreme Court, Texas appellate courts in Dallas, Houston, San Antonio, Corpus Christi, and Eastland, and state appellate courts in Arizona, Michigan, New York, Ohio, Oklahoma, and West Virginia.
Her most significant wins include:
