A Mercer County judge has dismissed a lawsuit brought by lawmakers trying to stop Gov. Chris Christie's $300 million renovation plan for the New Jersey State House.

Lawmakers who filed the suit said it was unconstitutional that they hadn't voted to approve the $300 million renovation plan.

State Judge Mary Jacobson said from the bench on Wednesday that the state Supreme Court ruled in a similar case that the question was moot because the money was already borrowed.

State Sen. Ray Lesniak and Assemblyman John Wisniewski argued in court that Christie improperly went around the Legislature to approve the sale of $300 million worth of bonds to fund the four-year project for the dilapidated executive statehouse.

Christie says the project is badly needed and defended how it was authorized, saying it was legal and proper.

Lt. Gov. Kim Guadagno, the Republican nominee for governor, has promised she would scrap the project if elected.
