The judge overseeing a lawsuit claiming that Sutter Health abused its market power to drive up health care prices in Northern California has pushed back the start of trial due to a shortage of jurors.

A coalition of about 1,500 California self-insured employers and trusts that pay for employee health care services sued Sutter, Northern California’s largest hospital chain, in 2014 claiming the company’s contract practices artificially inflate the prices of health care in the Bay Area and Sacramento Valley. The California attorney general filed similar claims against Sutter in 2018, and the consolidated cases were set to go to trial before San Francisco Superior Court Judge Anne-Christine Massullo on Thursday.
