SPOKANE, Wash. -

The clock could soon start ticking on the process of ousting Spokane mayor David Condon, if a judge rules there's enough evidence to move forward with a recall effort.

Yakima County Superior Court Judge Blaine Gibson will hear arguments on both sides of the issue Tuesday afternoon. He does not have to make a same-day ruling, but if he does, the calendar is put into motion.

If the judge supports even one of the four charges against Condon, petition supporters could begin collecting signatures September 29th. They'll have until March 28th to collect signatures and will need 12,355 deemed valid to put the issue on the ballot. Spokane County Auditor Vicki Dalton says most petition supporters need to collect 30 to 40 percent more than that to ensure they meet the threshold.

The elections office will then spend about two weeks verifying sigantures.

If enough valid signatures are gathered, the recall election would take place anywhere between May 31st and July 15th.

The calendar shifts if the mayor appeals the decision. If he does, it bypasses the state appeals court and goes directly to the state supreme court. The court would have two weeks to render a decision; if that happens, supporters could begin gathering signatures the next day.
