While serving at the Justice Department, Katyal argued numerous cases before the Supreme Court, including his successful defense (by an 8–1 decision) of the constitutionality of the Voting Rights Act of 1965inNorthwest Austin v. Holder.[11] Katyal also successfully argued in favor of the constitutionality of the Affordable Care Act, and won a unanimous decision from the Supreme Court defending former Attorney General John Ashcroft against alleged abuses of civil liberties in the war on terror in Ashcroft v. al-Kidd. Katyal is also the only head of the Solicitor General's office to argue in the Court of Appeals for the Federal Circuit.[12]
On May 24, 2011, speaking as Acting Solicitor General, Katyal delivered the keynote speech at the Department of Justice's Great Hall marking Asian American and Pacific Islander Heritage Month. Developing comments he had posted officially on May 20,[14] Katyal issued the Justice Department's first public confession of its 1942 ethics lapse in arguing the Hirabayashi and Korematsu cases in the US Supreme Court, which had resulted in upholding the internment of American citizens of Japanese descent. He called those prosecutions – which were only vacated in the 1980s – "blots" on the reputation of his office, which the Supreme Court explicitly considers as deserving of "special credence" when arguing cases, and "an important reminder" of the need for absolute candor in arguing the United States government's position on every case.[15] Katyal also lectured at Fordham Law School concerning that decision.[16]
Upon leaving the Obama administration, Katyal returned to Georgetown University Law Center, but also became a partner at the global law firm Hogan Lovells.[19] He specializes in constitutional law, national security, criminal defense, and intellectual property law, as well as running the appellate practice once run by John Roberts. During law school Katyal clerked one summer at Hogan Lovells, where he worked for Roberts before Roberts became a judge.[20]

In 2021, Katyal represented financial giant Citigroup in their efforts to recoup a mistaken transfer of $900 million to creditors of Revlon Inc.[29] He also worked with the prosecution team in State v. Chauvin.[30]
In 2022, Katyal argued for the respondents in Moore v. Harper before the Supreme Court, a case involving election law, redistricting and the independent state legislature theory.[32] The court rejected the independent legislature theory and thus upheld Katyal's position by a 6–3 vote.
Also in 2022, Katyal represented Johnson & Johnson in a civil suit against the company for selling talcum baby powder contaminated with carcinogens. His billing rate for this was $2,465 per hour.[33]
In addition to Gorsuch, Katyal spoke highly of Trump's nomination of Brett Kavanaugh to the Supreme Court.[38] In multiple tweets that were cited by Republican Senate Majority Leader Mitch McConnell in favor of Kavanaugh's confirmation,[39] Katyal praised Kavanaugh's "credentials [and] hardworking nature",[40] and described his "mentoring and guidance" of female law clerks as "a model for all of us in the legal profession".[41] Katyal has also called Kavanaugh "incredibly likable".[42]
The US Justice Department awarded Katyal the Edmund Randolph Award, the highest honor the department can bestow on a civilian. The National Law Journal named Katyal its runner-up for "Lawyer of the Year" in 2006 and in 2004 awarded him its Pro Bono award.[43][44]American Lawyer Magazine considered him one of the top 50 litigators nationally.[45]Washingtonian Magazine named him one of the 30 best living Supreme Court advocates;[46]
