Leaders of the state’s judicial branch unveiled a plan to lawmakers in Augusta on Wednesday to build three new courthouse complexes in York, Oxford and Waldo counties that would cost taxpayers an estimated $95 million. Ted Glessner, head administrator of the state’s courts, said in a presentation before the joint legislative Judiciary Committee that the three new court complexes would replace eight existing courthouses, some of which are aging and have safety issues. The members of the Judiciary Committee took no immediate action on the proposal.
