It seems like you're asking for definitions of certain legal terms. Here they are:

1. A law made by parliament: This is known as a statute or legislation. It is a law that has been formally enacted by the legislative branch of government, which in many countries is the parliament. This process usually involves drafting, debate, and approval by both houses of parliament, and then formal assent by the head of state.

2. A legally enforceable agreement: This is known as a contract. A contract is an agreement between two or more parties that creates mutual legal obligations. It can be oral or written, but it must involve an offer, an acceptance of that offer, and an exchange of value (consideration).

3. A harmful act that gives the victim a right to sue for compensation: This is known as a tort. A tort is a civil wrong (as opposed to a criminal act) that causes harm or loss to another individual. The person who suffers the harm can sue the person who caused it for damages.

4. A rule made by a court of law: This is known as a precedent or case law. It is a principle or rule established in a previous legal case that is either binding on or provides guidance for a court when deciding subsequent cases with similar issues or facts. This is a key principle of common law legal systems.
