Gwinnett County has asked the state Supreme Court to put on hold a judge’s ruling in a lawsuit that pits the county against its 15 cities.

A Superior Court judge ruled last month that Gwinnett cannot charge city residents for police and other services unless the cities consent. The ruling could shift the cost of services from city residents to those who live in unincorporated areas.

On Tuesday the county asked the state Supreme Court to put that order on hold until pending resolution of several issues.
