HOUSTON (AP) - A legal battle over pay raises for Houston firefighters shows no signs of being resolved anytime soon.

Lawyers for the city of Houston on Friday asked a judge to declare invalid a ballot measure approved in November that would give firefighters pay parity with city police officers.

This comes as Mayor Sylvester Turner and the firefighters' union had met to discuss ways to implement the measure.

The Houston Professional Fire Fighters Association says Turner is continuing to defy the will of the voters.

In a statement, Turner insisted the city is working to implement the measure while it also asks the judge to resolve legal questions regarding it.

Turner has said the city can't afford the measure's more than $100 million annual price tag and it could result in layoffs.
