What is the difference between statute and rules?

Answer 1

A statute is a law passed by the legislative branch of the US or a state. A rule, more properly called a regulation, is a directive adopted by the executive branch of the US or a state. Rules or regulations have the force and effect of laws. Regulations fill in the details of statutes that are written in a general sort of way.

Answer 2

A statute is the product of a legislature or Congress. Each year, those bodies pass laws, usually called "acts". Those acts are then "codified", which means that the laws are placed in the compilation of all the acts then in force and kept up to date, as in the United States Code or the Nevada Code or the California Code. Some States keep the "statutes" name, even though they are codified, like the Vermont Statutes or the New Mexico Statutes.

For instance, if the U.S. Congress passed a law having to do with agriculture, that law would be cited in the Statutes at Large, which come out every Congress. That statute would then be codified into Title 7 of the U.S. Code; Title 7 contains the laws on agriculture. Codification is usually done by a legislative codification committee.

Answer 3

They mean essentially the same thing, a body of regulations passed by a legislature.

Answer 4

A constitution is a framework for government. A statue is the law in the framework.
