Once the Governor has signed the bill, or 14 days have passed since he looked at it, my cousin takes over. The bill is stamped by the Office of the Great Seal with the Secretary of State's name and the time and date. It is given a public act number. It is now law. But, just because a bill becomes law does not mean the work is done.
Some bills are very general.
For example, a law may say that schools can offer driver education courses. Rules help define what those courses must include so that no matter where you take driver education, you will receive the same education as your friends. If a bill has to have rules, it will be sent to the right Department, like Education. After a rule is drafted, it is reviewed by a number of other offices. The Department will also hold public hearings.
