A plan to move the University of Maine School of Law and the University of Maine Graduate and Professional Center to a temporary home in downtown Portland got the official nod on Monday from University of Maine System trustees. The board vote paves the way for a temporary move to a leased space at 300 Fore St. until a new building goes up at the University of Southern Maine campus in Portland. Trustees also approved a host of capital projects but delayed final approval of the fiscal year 2022 budget "to provide time to develop a spending plan that holds tuition flat for in-state students for the upcoming academic year," according to a news release issued after the meeting.
