Whenever a town adopts or amends its general by-laws or zoning by-laws, within 30 days of adjournment of town meeting, the Town Clerk is required to submit them to the Attorney General's Office for review and approval. The Attorney General then has 90 days in which to decide whether the proposed amendments are consistent with the constitution and the laws of the Commonwealth. If the Attorney General finds an inconsistency between the proposed amendments and state law, the amendments or portions of them will be disapproved. The Municipal Law Unit is responsible for undertaking this review and for issuing a written decision approving or disapproving by-law amendments. Under the law, the Municipal Law Unit is required to review bylaws for consistency with state law and may not take policy considerations into account.
