A group opposing an initiative to raise Michigan's minimum wage is asking the Michigan Supreme Court to block the proposal from the November ballot.

Michigan Opportunity filed an appeal and a motion to expedite the decision on Thursday, Aug. 23, a day after the Michigan Court of Appeals ruled in favor of putting the One Fair Wage proposal before voters.

The group is seeking a decision by Dec. 31.

The initiative would raise the state's minimum wage from $9.25 per hour to $10 in 2019 and $12 by 2022.

Tipped workers -- who currently earn $3.52 before tips -- would get the full minimum wage by 2024.

The appeals court issued a ruling Wednesday, Aug. 22, that said the Michigan Secretary of State should take "all necessary measures" to put the issue before voters.

Supporters of the proposal needed 252,523 petition signatures to put it on the November 2018 ballot. They collected 372,105 signatures.

Staff of the Board of State Canvassers recommended putting the proposal on the ballot, saying supporters met the statutory requirements.

However, the board deadlocked, voting 2-2 on both a plan to deny the minimum wage proposal's certification for the ballot and to approve its certification.

Michigan Opportunity claims the One Fair Wage initiative violates the state constitution because if fails to properly reference the existing law it seeks to amend.

The group also argued for disqualifying petition signatures when people checked boxes for both city and township in the case of municipalities such as Ann Arbor or Kalamazoo when a city and township share the same name.

The appeals court ruling was a 2-1 vote. Judges Stephen Borrello and Jane Beckering ruled in favor of putting One Fair Wage on the ballot, while Judge Michael Riordan dissented.
