Appellate review is the general term for the process by which courts with
appellate jurisdiction take jurisdiction of matters decided by lower courts,
it is distinguished from judicial review in which the court has an
overriding constitutional or statutory right to determine if a lower court
or administrative decision is defective for jurisdictional or other reasons
(which may vary by jurisdiction).
In most jurisdictions the normal and preferred way of seeking appellate
review is by filing an appeal of the final judgment or appeallable interim
Court order in a case such as the denial of a request for an interim
injunction which are often appeallable as of right.
In Anglo=American common law legal system courts, appellate review of lower
court decisions may also be obtained by filing a petition for review by
prerogative writ in certain cases. There is no corresponding right to a writ
in any pure or continental civil law legal systems, though some mixed system
such as Quebec recognize these prerogative writs.
