The city of Phoenix filed a brief to the Arizona Supreme Court on Tuesday making the case that its plan for new airport fees on Uber and Lyft are constitutional.
On Jan. 21, Arizona Attorney General Mark Brnovich filed an action asking the state’s highest court to rule on whether the fees for rides to and from Phoenix Sky Harbor International Airport violated the Arizona Constitution.
Brnovich believes the plan violates a voter-approved amendment banning new taxes or tax increases on services.
The city, meanwhile, maintains that the plan approved Dec. 18 is legal, saying the fees are a charge for property use, not taxes.
The fees were scheduled to go into effect Feb. 1, but the city agreed to delay their implementation until after the Supreme Court ruled.
