In a significant gerrymandering case scheduled to be heard by the U.S. Supreme Court on Oct. 3, New York City’s Holwell Shuster & Goldberg represents pro bono 65 former and current state lawmakers from eight states—a roster that includes 26 Republicans and 39 Democrats—who filed a friend of the court brief this week backing the challengers of a Wisconsin redistricting plan.

Holwell Shuster’s client list didn’t, however, start out as robust and diverse as it is now, concedes Vincent Levy, the attorney of record on the brief and a partner who previously clerked for U.S. Supreme Court Justice Ruth Bader Ginsburg.
