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 respected appellate litigators. In the Chambers ranking of top appellate lawyers nationwide, she is the highest ranked appellate lawyer from Texas in 2015, 2016, 2017, and 2018, as well as one of the top appellate lawyers in America. She has argued and won more cases on behalf of businesses before the U.S. Supreme Court than any Texas lawyer.
Among her numerous accolades, Mrs. Ho has been named a “Distinguished Leader” (Texas Lawyer, Sep. 1, 2017) and “Appellate MVP” (Law360, Nov. 23, 2015), and recognized on the “Appellate Hot List” (National Law Journal, Nov. 16, 2015). She has also been profiled in “Litigation Powerhouse” (Law360, Aug. 10, 2016), “Supreme Court Insider” (National Law Journal, July 21, 2016), “Supreme Court Specialists, Mostly Male, Dominated Arguments This Term” (National Law Journal, May 11, 2016), “Lifetime Achievement Awards: Attorney of the Year Finalist” (Texas Lawyer, Nov. 2, 2015), “Litigation Department of the Year” (Texas Lawyer, June 1, 2015), “Employment Group of the Year” (Law360, Jan. 13, 2015), “A Supreme Month: Lawyer Credits Preparedness in Ability to Argue Two U.S. High Court Cases in Three Weeks” (Texas Lawyer, Dec. 8, 2014), “High Court Debuts for Two Lawyers” (National Law Journal, Nov. 3, 2014), “Women in Business Awards” (Dallas Business Journal, Aug 29, 2014), “Litigation Departments of the Year” (Texas Lawyer, June 2, 2014), “Winning Women” (Texas Lawyer, Aug. 22, 2011), and “High court practitioners: increasingly diverse” (National Law Journal, June 6, 2011).
U.S. Supreme Court Practice
Mrs. Ho has argued multiple times before the U.S. Supreme Court. 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.” EmpiricalSCOTUS.com ranked her among “the most successful attorneys that currently practice before the Court.”
She first attracted attention as a Supreme Court litigator when she argued two Supreme Court cases in 21 days during October Term 2014. Her win in M&G Polymers USA LLC v. Tackett was a “significant ruling for employers across the U.S.” (Law360, Aug. 10, 2016), overturning longstanding circuit precedent and “pav[ing] a new path for companies paying millions of dollars in retiree health care benefits” (Law360, Nov. 23, 2015). In Perez v. Mortgage Bankers Association, “several justices agreed with Ho’s contention that SCOTUS should revisit and overrule its own precedent” concerning deference to administrative interpretations of agency rules (Law360, Nov. 23, 2015).
In 2017, Mrs. Ho again argued two cases before the U.S. Supreme Court. In McLane Company, Inc. v. EEOC, she convinced the Court to limit the EEOC’s subpoena power, a win that the employment defense bar has described as “good news for employers across the country.” She also argued in Oil States Energy Services LLC v. Greene’s Energy Group, LLC, a “colossus” that has “immense commercial implications” (National Law Journal). Intellectual property experts have called it “the most important patent case in modern history,” and Supreme Court watchers credited her with “pick[ing] up two votes that pundits thought unreachable.”
Federal and State Appellate Court Practice
Mrs. Ho has presented over 50 oral arguments in federal and state courts nationwide. She has appeared in every federal court of appeals in the country, including en banc arguments before the Fourth and Sixth Circuits.
