The legislature passes statutes which are later put into the federal code of laws or pertinent state code of laws. Statutory law also covers areas which are governed exclusively by statutory law and where case law has no impact. Corporate law and wills and probate administration are two areas governed by state statutes while patent, copyright and trademark laws are governed by federal statutes. Consumer law is covered by both state and federal statutes while protecting consumers from deceptive trade practices and any unsafe products and activities that threaten a consumer. Employment law is mostly governed by federal statutes while each state also has statutes which govern certain areas of employment.

It is governed by federal statutes while states also have their own relevant statutes. Statutory law differs from common law which is that law which is announced in court decisions or case laws.

Since that time statutory law has expanded considerably by codifying, or arranging topically, common law doctrines through the enactment of statutes. Statutory law has also formed out of necessity.
