Section 380.6 - Effective date.

380.6 Effective date.
Measures passed by the council become effective in one of the following ways:
1. a. An ordinance or amendment signed by the mayor becomes effective when the ordinance or a summary of the ordinance is published, as provided in section 380.7, subsection 3, unless a subsequent effective date is provided within the ordinance or amendment.
b. A resolution signed by the mayor becomes effective immediately upon signing.
c. A motion becomes effective immediately upon passage of the motion by the council.
2. The mayor may veto an ordinance, amendment, or resolution within fourteen days after passage. The mayor shall explain the reasons for the veto in a written message to the council at the time of the veto. Within thirty days after the mayor’s veto, the council may pass the measure again by a vote of not less than two-thirds of all of the members of the council. If the mayor vetoes an ordinance, amendment, or resolution and the council repasses the measure after the mayor’s veto, a resolution becomes effective immediately upon repassage, and an ordinance or amendment becomes a law when the ordinance or a summary of the ordinance is published, unless a subsequent effective date is provided within the ordinance or amendment.
3. If the mayor takes no action on an ordinance, amendment, or resolution, a resolution becomes effective fourteen days after the date of passage and an ordinance or amendment becomes a law when the ordinance or a summary of the ordinance is published, but not sooner than fourteen days after the date of passage, unless a subsequent effective date is provided within the ordinance or amendment.
