A coalition of environmental organizations filed a lawsuit Tuesday in U.S. District Court for the District of Connecticut contesting the legality of so-called energy sweeps contained in the state’s October 2017 budget.

At issue is the rerouting of $175 million from three funds for clean energy and energy efficiency programs, and putting the money in the state’s general fund. The lawsuit, which was filed in federal court in New Haven, seeks a preliminary injunction as the budget is set to take effect June 30.
