Arizona Attorney General Mark Brnovich says a new $4 fee on Uber and Lyft rides to and from Phoenix Sky Harbor International Airport is “very likely” unconstitutional.
His statement ups the ante in the showdown that has led the ride-hailing giants to threaten to abandon the airport service.
Brnovich says the fees approved by the Phoenix City Council violated a 2018 ballot measure prohibiting higher taxes on services.
He says he'll ask the Arizona Supreme Court for a final determination.
Lawyers for the city of Phoenix say the higher fees are permissible charges for businesses to use the airport.
