SACRAMENTO — California’s court leaders on Wednesday pleaded with lawmakers to spare the judicial system from the full brunt of $100 million in planned budget cuts and millions of dollars more in cost overruns.

“The effect of what’s on the table now comes very close to shutting down major portions of the court system,” William Vickrey, the Administrative Office of the Courts’ administrative director, told a budget subcommittee. “We could literally find ourselves shutting the civil system down and still not come close to the entirety of the reductions.”
