Laws are created through several processes. Statutes are laws passed by legislatures to address needs and problems, with the U.S. Congress passing federal statutes and state legislatures passing state statutes. Regulations are additional rules created by government departments and agencies to provide details related to statutes. Common law refers to the system used in England where judges made rulings based on customs and precedents from previous similar cases, and this system influences laws in countries like the U.S. today. The Constitution is the foundational collection of laws that establishes rules for how the government operates and new laws are made or changed.
