Mark Gaber

Mark has led CLC’s redistricting program to major successes since the 2020 Census. He argued for petitioners in the Wisconsin Supreme Court in Clarke v. Wisconsin Election Commission, which resulted in the invalidation of Wisconsin’s state legislative maps and the transformation of the state’s legislative maps from being among the most politically skewed to among the most politically fair in the country. He is lead counsel in League of Women Voters of Utah v. Utah State Legislature, which challenges the Utah legislature’s repeal of a voter-adopted initiative reforming the state’s redistricting process and its enactment of an extremely gerrymandered congressional map. In that case, Mark has (to date) argued twice in the Utah Supreme Court, resulting in two unanimous decisions in favor of CLC’s clients.

Mark has also led CLC’s redistricting team to victories enforcing the Voting Rights Act (VRA). These include two cases on behalf of North Dakota’s Native American voters, where he has argued in the Eighth Circuit against a challenge aiming to neutralize the VRA by precluding citizens from filing suit and where CLC’s clients have secured two legislative districts providing Native American voters an equal opportunity to elect their preferred candidates. Mark also led CLC’s successful challenge to Washington’s legislative map, which was found to discriminate against Latino voters in the Yakima region, and CLC’s ongoing challenge to the racially discriminatory Galveston County, Texas map.

Prior to joining CLC, Mark was an associate at Jenner & Block LLP in the firm's Appellate & Supreme Court, Election Law & Redistricting, and Media and First Amendment practice groups. Mark clerked for the Hon. Judith W. Rogers on the United States Court of Appeals for the D.C. Circuit.

Mark is a graduate of Stanford Law School (J.D., 2010) and St. Norbert College (B.A., 2005), and is a Harry Truman Scholar. He is admitted to practice law in the District of Columbia and California (inactive), as well as the bars of the Supreme Court of the United States, the Fourth, Fifth, Sixth, Eighth, Ninth, Tenth, Eleventh and D.C. Circuits, and the United States District Court for the District of Columbia, the Western District of Michigan, the District of North Dakota and the Western District of Wisconsin. Mark joined CLC in 2017.
