The court on Thursday ruled for Dianne Knox and other nonmembers of the Service Employees International Union's Local 1000, who wanted to object and opt out of a $12 million special assessment the union required from its California public sector members. 

Knox and others said the union did not give them a legally required notice that the increase was coming.

 

The union, and the 9th U.S. Circuit Court of Appeals, said the annual notice that the union gives was sufficient. The high court disagreed in a 7-2 judgment written by Justice Samuel Alito.
