The TIME Coalition is taking its legal challenge to the Arizona Supreme Court, after a Superior Court judge ruled Wednesday in favor of Secretary of State Jan Brewer, rejecting TIME's attempt to reinstate signatures invalidated by Brewer's office.

Despite the setback, the judge also ruled TIME's complaint against the Maricopa County Recorder's office could move ahead. However, according to attorney Charles Blanchard, who is handling the complaint on TIME's behalf, reinstating signatures in Maricopa County alone won't provide enough to get TIME balloted.

According to Blanchard, the argument for appeal is due in the Supreme Court on Monday. The court will have to move quickly in order to have a decision by Aug. 28, the deadline for the ballot to be finalized.
