Maryland?s highest court on Friday ruled that Montgomery County Council Member Tom Perez did not have the constitutional qualifications to run for attorney general and should be taken off the ballot.

The ruling turns the Sept. 12 Democratic primary into a head-to-head contest between Montgomery County State?s Attorney Doug Gansler and former Baltimore State?s Attorney Stuart Simms. The winner will face Republican Frederick State?s Attorney Scott Rolle to replace retiring Attorney General Joseph Curran.
