This bill introduces a new section to RSA 643, specifically addressing the conduct of delegates to a convention called under Article V of the United States Constitution. It establishes that a delegate who knowingly supports or approves the proposal of an unauthorized amendment—defined as any amendment outside the scope of the legislative instructions provided by the general court—will be guilty of a class B felony. The bill defines key terms such as "Article V application," "Article V convention," "delegate," "legislative instructions," and "unauthorized amendment" to clarify the responsibilities and limitations placed on delegates.

The effective date for this legislation is set for January 1, 2026. The fiscal impact of the bill is indeterminable, as it may affect the judicial and correctional systems due to the introduction of new criminal penalties. This could lead to changes in prosecution, incarceration, probation, and parole costs for the state, counties, and local governments. The bill does not anticipate any revenue generation but may incur expenditures related to its enforcement and implementation.
