Judicial interpretation is the way in which the judiciary construes the law, particularly constitutional documents, legislation and frequently used vocabulary.
This is an important issue in some common law jurisdictions such as the United States, Australia and Canada, because the supreme courts of those nations can overturn laws made by their legislatures via a process called judicial review.
As a result, how justices interpret the constitution, and the ways in which they approach this task has a political aspect.
Terms describing types of judicial interpretation can be ambiguous; for example, the term judicial conservatism can vary in meaning depending on what is trying to be "conserved".
Phrases which are regularly used, for example in standard contract documents, may attract judicial interpretation applicable within a particular jurisdiction whenever the same words are used in the same context.
