Story highlights The governor-elect says the legislative changes are unconstitutional

The judge sets a new hearing for next Thursday

(CNN) The political battle between North Carolina's Republican-controlled legislature and Democratic Governor-elect Roy Cooper has moved into the courtroom.

Friday, Cooper asked a judge to block a new law that would have disbanded the state elections board. If that law goes into effect, the elections board's duties would be assumed by another agency that includes the state ethics board -- a move that would increase the legislature's appointive power and decrease the governor's.

Later Friday, Wake County Superior Court Judge Donald Stephens approved Cooper's request for a temporary restraining order, saying there might be irreparable harm in disbanding the board.

Stephens said he wanted additional time to hear arguments and he set another hearing for next Thursday.

"The leadership of the North Carolina General Assembly moved ... to curtail, in significant ways, the executive powers that will pass to him on January 1," the request for an injunction said. "Those changes are unconstitutional because they violate the separation of powers provisions enshrined in the North Carolina Constitution by shifting control over that agency away from the Governor to the General Assembly."
