Supreme courtIn most legal jurisdictions, a supreme court, also known as a court of last resort, apex court, and high (or final) court of appeal, is the highest court within the hierarchy of courts. Broadly speaking, the decisions of a supreme court are not subject to further review by any other court. Supreme courts typically function primarily as appellate courts, hearing appeals from decisions of lower trial courts, or from intermediate-level appellate courts. However, not all highest courts are named as such.
Original jurisdictionIn common law legal systems, original jurisdiction of a court is the power to hear a case for the first time, as opposed to appellate jurisdiction, when a higher court has the power to review a lower court's decision. In India, the Supreme Court has original, appellate and advisory jurisdiction. Its exclusive original jurisdiction extends to all cases between the Government of India and the States of India or between Government of India and states on one side and one or more states on the other side or cases between different states.
Trial courtA trial court or court of first instance is a court having original jurisdiction, in which trials take place. Appeals from the decisions of trial courts are usually made by higher courts with the power of appellate review (appellate courts). Most appellate courts do not have the authority to hear testimony or take evidence, but instead rule solely on matters of law. In the trial court, evidence and testimony are admitted under the rules of evidence established by applicable procedural law and determinations called findings of fact are made based on the evidence.
European Court of JusticeThe European Court of Justice (ECJ), formally just the Court of Justice (Cour de Justice), is the supreme court of the European Union in matters of European Union law. As a part of the Court of Justice of the European Union, it is tasked with interpreting EU law and ensuring its uniform application across all EU member states under Article 263 of the Treaty of the Functioning of the European Union (TFEU). The Court was established in 1952, and is based in Luxembourg.
Double jeopardyIn jurisprudence, double jeopardy is a procedural defence (primarily in common law jurisdictions) that prevents an accused person from being tried again on the same (or similar) charges following an acquittal or conviction and in rare cases prosecutorial and/or judge misconduct in the same jurisdiction. Double jeopardy is a common concept in criminal law. In civil law, a similar concept is that of res judicata. Variation in common law countries is the peremptory plea, which may take the specific forms of autrefois acquit ('previously acquitted') or autrefois convict ('previously convicted').
Appellate courtAn appellate court, commonly called a court of appeal(s), appeal court, court of second instance or second instance court, is any court of law that is empowered to hear an appeal of a trial court or other lower tribunal. In much of the world, court systems are divided into at least three levels: the trial court, which initially hears cases and reviews evidence and testimony to determine the facts of the case; at least one intermediate appellate court; and a supreme court (or court of last resort) which primarily reviews the decisions of the intermediate courts, often on a discretionary basis.
Ex post facto lawAn ex post facto law is a law that retroactively changes the legal consequences (or status) of actions that were committed, or relationships that existed, before the enactment of the law. In criminal law, it may criminalize actions that were legal when committed; it may aggravate a crime by bringing it into a more severe category than it was in when it was committed; it may change the punishment prescribed for a crime, as by adding new penalties or extending sentences; it may extend the Statute of limitations; or it may alter the rules of evidence in order to make conviction for a crime likelier than it would have been when the deed was committed.
Constitution of IndiaThe Constitution of India is the supreme law of India. The document lays down the framework that demarcates fundamental political code, structure, procedures, powers, and duties of government institutions and sets out fundamental rights, directive principles, and the duties of citizens. It is the longest written national constitution in the world. It imparts constitutional supremacy (not parliamentary supremacy, since it was created by a constituent assembly rather than Parliament) and was adopted by its people with a declaration in its preamble.
