Can A bill can become a law in Arizona even if the Governor does not sign it?

Yes, in Arizona, a bill can become law without the Governor's signature if the Governor does not act on it within five days (excluding Sundays) after receiving it. If the bill is presented to the Governor while the legislature is in session and the Governor takes no action, it automatically becomes law. However, if the legislature is not in session, the Governor has a longer period to consider the bill, and failure to sign it does not result in it becoming law.
