For years, Atlanta attorney Emmet Bondurant looked for the perfect case on which to build a successful challenge to partisan gerrymandering.

He found the germ of it in a pro se complaint that originated in Maryland before landing in the lap of the U.S. Supreme Court in 2015. Bondurant is a founding partner of Atlanta’s Bondurant, Mixson & Elmore and a 50-year veteran of legal voting rights battles.
