Who creates statutes?

It depends on where you live. The short answer is usually, in a republic, such as in the United States, statutes are created by the legislature and the executive. At the federal level, Congress and the President create Federal Laws/statutes. Laws are usually organized as follows: A constitution sets the highest law. Then, statutes follow the constitution. Constitutions usually state how statutes are created. Many states only allow the elected representatives (the legislature) to propose and sign-off on bills. These bills are given to the executive to sign. If the executive vetos the bill, the bill goes back to the legislature, which can then vote, usually by super-majority, to override the veto. Once a bill is passed by the legislature and executive, or by the legislature over the executive's veto, it become a law. That law is codified in a statute book for easy reference. In states, like Florida, the law itself is what needs to be followed, not the statute, which is merely a copy of the law and a codified version of the law. That being said, laws are often created with statutes in mind, and might reference the statute itself when making additions or deletions to the law.
