Common Law is a legal system that originated in England and is based on court decisions and judicial precedents rather than written laws. This means that judges play a crucial role in interpreting laws and their rulings can set important examples for future cases. Over time, these decisions create a body of law that evolves with society's needs. In many countries, including the United States and Canada, Common Law is used alongside statutory laws created by legislatures. This combination allows for flexibility and adaptability in the legal system, as judges can consider the unique circumstances of each case while still adhering to established legal principles.
