oral arguments in a 2009 case involving the
Atlantic Yards development in Brooklyn Although some courts permit appeals at preliminary stages of
litigation, most litigants appeal final orders and judgments from lower courts. A fundamental premise of many legal systems is that appellate courts review questions of law
de novo, but appellate courts do not conduct independent fact-finding. Instead, appellate courts will generally defer to the record established by the
trial court, unless some error occurred during the fact-finding process. In some jurisdictions on the other hand, such as the Netherlands, appellate courts review cases in their entirety, which includes fact-finding. Many
jurisdictions provide a
statutory or
constitutional right for litigants to appeal adverse decisions. However, most jurisdictions also recognize that this right may be
waived. In the United States, for example, litigants may waive the right to appeal, as long as the waiver is "considered and intelligent". The appellate process usually begins when an appellate court grants a party's
petition for review or petition for certiorari. Unlike trials, which many
common law jurisdictions typically perform with a
jury, appeals are generally presented to a judge, or a panel of judges. Before hearing oral
argument, parties will generally submit
legal briefs in which the parties present their arguments at length in writing. Appellate courts may also grant permission for an
amicus curiae to submit a brief in support of a particular party or position. After submitting briefs, parties often have the opportunity to present an
oral argument to a
judge or panel of judges. During oral arguments, judges often ask questions to
attorneys to challenge their arguments or to advance their own legal theories. After deliberating in chambers, appellate courts issue formal written opinions that resolve the
legal issues presented for review. The appeal may end with a reversal, in which the lower court's decision is found to be incorrect (resulting in the original judgement being vacated, and the lower court instructed to retry the case) or an affirmation, in which the lower court's decision is found to be correct. == Appellate courts ==
