A sweeping bill introduced by a Democratic senator Wednesday would greatly increase the size of the Supreme Court, make it harder for the justices to overturn laws, require justices to undergo audits and remove roadblocks for high court nominations.

The legislation by Sen. Ron Wyden (D-Ore.) is one of the most ambitious proposals to remake a high court that has suffered a sharp decline in its public approval after a string of contentious decisions and ethics scandals in recent years. It has little chance of passing at the moment, since Republicans have generally opposed efforts to overhaul the court.
