“Statutory” law comes from federal and state legislative bodies. Those men and women we elect to represent us make law concerning a variety of things, like family law, contract law, employment law, traffic law, etc. Do your own independent research into how the legislative process works. For example, years ago Nevada did not have a seatbelt law. A member of the Nevada Legislature had an “idea” that a seatbelt law would help save lives. That “idea” eventually became a “law.” What process occurred?
