The U.S. Sentencing Commission’s sole remaining member urged the White House to nominate individuals to the panel after Justices Sonia Sotomayor and Amy Coney Barrett said this week that the vacancies have left a circuit split unresolved.

The seven-seat commission, created by Congress in 1984 to address disparities in federal sentencing, has lacked quorum for the past three years. U.S. District Judge Charles Breyer, who as the panel’s acting chair is its only member, said the justices’ statement will be “very helpful” in pressing the Biden administration to complete the vetting process and name nominees.
