Six months after agreeing to a $575 million settlement in a closely watched antitrust case filed by California Attorney General Xavier Becerra, Sutter Health has yet to pay a single dollar, and no operational changes have gone into effect. The nonprofit health care giant was accused of using its market dominance in Northern California to illegally drive up prices.

Late last week, lawyers for Sutter filed a motion requesting that San Francisco Superior Court Judge Anne-Christine Massullo delay approval of the settlement for an additional 90 days, due to "catastrophic" losses stemming from the COVID-19 pandemic. Massullo originally was scheduled to rule on the agreement in February, but in April granted an earlier request from Sutter for a 60-day delay in the proceedings.
