The state Supreme Court declined Wednesday to hear an appeal by the city of Costa Mesa in a case against an employee union.
Also, the court denied a related request to strike an appeals court decision from case law.
That denial could have widespread effects in other California cities. As they seek to privatize services such as street sweeping to save costs, some municipalities may be blocked by this appeals court ruling, some legal experts have said. The appellate decision essentially prohibits the majority of cities from privatizing except for certain "specialized services" such as legal or financial functions.
This has the effect of "strengthening outsourcing protections for public workers across the State of California," a news release from the Orange County Employees Association said.
