A Minnesota Supreme Court ruling has removed a legal barrier that threatened to block or delay a new government office building for state senators. Thursday’s decision effectively ends a court fight that could have delayed an early July groundbreaking. Former Republican lawmaker Jim Knoblach was suing to stop it. But he couldn’t convince the courts to let the case proceed without his guarantee to cover the cost of delays if he lost. The building to be erected near the Capitol is projected to cost $90-million, with taxpayers covering all but $13-million. It’s been a political flashpoint though. Republicans say it represents misplaced priorities while Democrats say the structure is needed to relieve crowding in the Capitol, which is undergoing a massive renovation.
