Criminal law deals with offenses against society and aims to punish offenders through fines or imprisonment. It has a high burden of proof of "beyond reasonable doubt". Civil law deals with individuals' rights and duties toward each other, and violations of these duties constitute torts. Civil cases have a lower burden of proof of "balance of probabilities" and seek to remedy wrongs through compensation. Common law comprises established customs and precedents set in past court rulings, while statute law consists of legislation passed by Parliament.
