MONTPELIER, Vt. (AP) — A group that advocates for state legislatures filed court papers Monday saying a federal judge erred when he relied on excerpts from Vermont’s legislative record for a ruling that sharply limited the state’s authority over the Vermont Yankee nuclear plant.

The National Conference of State Legislatures was among several parties filing friend-of-the-court, or amicus, briefs supporting the state’s appeal of a January ruling by Judge J. Garvan Murtha of the U.S. District Court in Brattleboro.
