Step 13: The Idea Becomes Law!

The act, which began its journey through the legislative process as an idea, becomes law in Massachusetts if it is signed by the governor, allowed to become law by the governor without his or her signature, or if a veto by the governor is overridden. The new law usually takes effect in 90 days but can become effective immediately if it includes an emergency preamble which must be adopted by a two-thirds vote of the legislature or by an emergency declaration by the governor.
