The new restrictions for the Southern California region go into effect at 11:59 p.m. Sunday, Dec. 6, and must stay in place for at least three weeks because the region’s intensive care capacity has dropped below 15 percent. The order came after a flurry of court activity last week in a case initially centered around two San Diego strip clubs — Cheetahs Gentlemen’s Club and Pacers Showgirls International — that had filed a lawsuit seeking to prevent state and local authorities from enforcing certain restrictions aimed at slowing the spread of COVID-19. The strip clubs argued that they were operating safely, with reduced capacities and heightened safety measures, and that no COVID-19 cases had been traced to the businesses.
