TALLAHASSEE, Fla. — The League of Women Voters’ Florida branch is trying to stop Gov. Rick Scott from appointing three state Supreme Court justices on the day he leaves office.

The league and the government watchdog group Common Cause filed a petition with the Supreme Court on Wednesday saying his successor should make the appointments.

Age limits are forcing three justices to retire on the day Scott leaves office in January 2019 because of term limits. Scott has said he plans to name their replacements that same morning.

The decision could change the balance of the court for decades. If Scott gets his way, the seven-member court will be stacked with six conservative judges as more liberal justices Barbara Pariente, Fred Lewis and Peggy Quince step down.
