Law made by judges and which is based on custom with my singin a. common law b. constitutional law c. statue law d. criminal law

The correct answer is a. common law.Common law, also known as case law or precedent, is a body of law developed by judges through decisions of courts and similar tribunals, rather than through legislative statutes or executive branch action. It is based on customs, traditions, and previous judicial decisions, and is often contrasted with statutory law, which is created by legislative bodies.Constitutional law refers to the body of law which defines the role, powers, and structure of different entities within a state, namely, the executive, the parliament or legislature, and the judiciary, as well as the basic rights of citizens and, in federal countries such as the United States and Canada, the relationship between the central government and state or provincial governments.Statute law is written law set down by a legislature or by a legislating body, as opposed to oral or customary law; or law made by judges under the doctrine of judicial law-making.Criminal law is the body of law that relates to crime. It proscribes conduct perceived as threatening, harmful, or otherwise endangering to the public, health, safety, and moral welfare of people.
