Judicial review
When a court decision is appealed, it is known as an "appeal." But there are many administrative agencies or tribunals which make decisions or deliver government services of one sort or another, the decisions of which can also be "appealed." In many cases, the "appeal" from administrative agencies is known as "judicial review" which is essentially a process where a court of law is asked to rule on the appropriateness of the administrative agency or tribunal 's decision. Judicial review is a fundamental principle of administrative law . A distinctive feature of judicial review is that the "appeal" is not usually limited to errors in law but may be based on alleged errors on the part of the administrative agency on findings of fact.

Jurisdiction
Refers to a court's authority to judge over a situation usually acquired in one of three ways: over acts committed in a defined territory (eg. the jurisdiction of the Supreme Court of Australia is limited to acts committed or originating in Australia), over certain types of cases (the jurisdiction of a bankruptcy court is limited to bankruptcy cases), or over certain persons (a military court has jurisdiction limited to actions of enlisted personnel).

Jury
A group of citizens randomly selected from the general population and brought together to assist justice by deciding which version, in their opinion, constitutes "the truth" given different evidence by opposing parties.

Justice
Fairness. A state of affairs in which conduct or action is both fair and right, given the circumstances. In law, it more specifically refers to the paramount obligation to ensure that all persons are treated fairly. Litigants "seek justice" by asking for compensation for wrongs committed against them; to right the inequity such that, with the compensation, a wrong has been righted and the balance of "good" or "virtue" over "wrong" or "evil" has been corrected.
