A bill signed by the governor, or passed by two-thirds of both branches over his veto, becomes a law. It is usually effective in ninety days. The day after the governor signs the bill is considered to be the first day, and each succeeding day, including Sundays and holidays is counted until the ninetieth. Laws considered "emergency" in nature take effect immediately upon signing if the legislature has voted to attach an "emergency preamble" to the bill. Adoption of the preamble requires a two-thirds standing vote of the membership. The governor may also declare an act to be an emergency law and make it effective at once. A special act takes effect thirty days from the day it is signed, unless it contains a provision to make it effective immediately.
