In the case of Friedrichs v. California Teachers Association, the Supreme Court in a vote of 4 to 4 upheld a Ninth Circuit Court decision that held that a public-sector union can collect fees from workers who choose not join the union and do not want to pay for the unions' collective bargaining activities. Under California law, public employees who choose not to join unions must still pay a fair share service fee or agency fee.  This fee is typically equivalent to the fees paid by members as dues minus fees paid for lobbying.  These fees are instituted to pay for the costs of collective bargaining.  

California law allows teachers to opt out of the 30% or so of the dues that go to political lobbying.  The employees cannot, however, opt out of the portion of the dues that the union determines to be used for collective bargaining.  

The Center for Individual Rights, a conservative legal advocacy group, have said that they will file a rehearing petition.  The rehearing would not be slated until the new term of the court which is to begin on October 3.
