Criminal law is a branch of law that defines crimes, regulates criminal behavior, and establishes punishments for violations. It protects society by deterring unlawful conduct and holding offenders accountable. Criminal law differs from civil law because it involves offenses against the state or public order rather than private disputes. In 2026, criminal law continues to evolve with changes in cybercrime regulation, digital evidence standards, and human rights protections. This guide explains criminal law in simple international English, covering definitions, types of crimes, elements of a crime, legal procedures, rights of the accused, penalties, and future developments.
