In addition, some bills specify the exact date when they are to take effect, which is usually a period of time longer than ninety days.

Publication of Missouri laws

All bills which become law are reported to the Secretary of State. The Joint Committee on Legislative Research publishes each year's laws in the Laws of Missouri. In addition, the Revisor of Statutes updates another publication, the Revised Statutes of Missouri, to reflect the changes made in the law each year.
