In Arizona, your driver’s license can be suspended solely on being accused of driving under the influence

In Arizona, your driver’s license can be suspended solely on being accused of driving under the influence. Kanye West was driving in Arizona and was stopped on suspicion of DUI when he was not intoxicated (for some reason, Kanye acting like himself appeared to be under the influence of drugs when speaking with the officer) and had his license suspended.

The way a license is suspended in Arizona, you must first go to a hearing at the DMV where it will be decided if your license is suspended or not. Once you lose at a DMV hearing, you can appeal the decision to the County Court of Arizona. If you lose at the County Court of Arizona, you then appeal to the Supreme Court of Arizona.

Kanye, not wanting to waste time took his case immediately to the Supreme Court of Arizona, without first going to the DMV hearing. They refused to hear his case.

Please explain if the Supreme Court of Arizona can refused to hear his case. If they can refuse to hear his case, why can they do so?
