Court of first instance in the context of "High Court of Justice"

The High Court of Justice in London, known properly as His Majesty's High Court of Justice in England, together with the Court of Appeal and the Crown Court, are the Senior Courts of England and Wales. Its name is abbreviated as EWHC (England and Wales High Court) for legal citation purposes.

The High Court deals at first instance with all high-value and high-importance civil law (non-criminal) cases; it also has a supervisory jurisdiction over all subordinate courts and tribunals, with a few statutory exceptions, though there are debates as to whether these exceptions are effective.

The Chancellor of the High Court, known until 2005 as the Vice-Chancellor of the High Court, is the head of the Chancery Division of the High Court of Justice of England and Wales. This judge and the other two heads of divisions (Family and King's Bench) sit by virtue of their offices often, as and when their expertise is deemed relevant, in a panel in the Court of Appeal (England and Wales). As such this judge ranks equally to the President of the Family Division and the President of the King's Bench Division.

From 1813 to 1841, the solitary and from 1841 to 1875, the three ordinary judges of the Court of Chancery – rarely a court of first instance until 1855 – were called vice-chancellors. The more senior judges of the same court were the Lord Chancellor and the Master of the Rolls (who were moved fully to the Court of Appeal above in 1881). Each would occasionally hear cases alone or make declarations on paper applications alone. Partly due to the old system of many pre-pleadings, pleadings, and hearings before most cases would reach Chancery the expense and duration of proceedings was pilloried in art and literature before the reforms of the late 19th century. Charles Dickens set Bleak House around raised hopes in a near-incomprehensible, decades-long case in Chancery (Jarndyce and Jarndyce), involving a decision on an increasingly old will which was rendered useless as all of the deceased's wealth was – unknowingly to the prospective beneficiaries – absorbed in legal costs. Reform swiftly followed.

Oslo District Court (Norwegian: Oslo tingrett) is a district court located in Oslo, Norway. This court is based at the Oslo Courthouse in the city of Oslo. The court serves the entire city of Oslo and the court is subordinate to the Borgarting Court of Appeal. As the largest district court in Norway, it handles about 20% of all cases in the country. The court handled 3,000 criminal and 2,200 civil cases, as well as 7,200 summary proceedings in 2007.

It is led by a chief justice (sorenskriver), and has 100 appointed professional and deputy judges. These are divided into eight sections. In addition, the court has 105 administrative employees, of which 30 are in central administration, 59 in judicial-related jobs and 16 in security. These are led by a managing director. The court is a court of first instance. Its judicial duties are mainly to settle criminal cases and to resolve civil litigation as well as bankruptcy. The administration and registration tasks of the court include death registration, issuing certain certificates, performing duties of a notary public, and officiating civil wedding ceremonies. Cases from this court are heard by a combination of professional judges and lay judges.

The High Court of Justiciary (Scottish Gaelic: Àrd-chùirt a' Cheartais) is the supreme criminal court in Scotland. The High Court is both a trial court and a court of appeal. As a trial court, the High Court sits on circuit at Parliament House or in the adjacent Justiciary Building (the former Sheriff Court building) in the Old Town in Edinburgh, or in dedicated buildings in Glasgow and Aberdeen. The High Court sometimes sits in various smaller towns in Scotland, where it uses the local sheriff court building. As an appeal court, the High Court sits only in Edinburgh. On one occasion the High Court of Justiciary sat outside Scotland, at Zeist in the Netherlands during the Pan Am Flight 103 bombing trial, as the Scottish Court in the Netherlands. At Zeist the High Court sat both as a trial court, and an appeal court for the initial appeal by Abdelbaset al-Megrahi.

The president of the High Court is the Lord Justice General, who holds office ex officio by virtue of being Lord President of the Court of Session, and his depute is the Lord Justice Clerk. The remaining judges are the Lords Commissioners of Justiciary, who hold office ex officio by virtue of being appointed as Senators of the College of Justice and judges of the Court of Session. As a court of first instance trials are usually heard with a jury of 15 and a single Lord Commissioner of Justiciary; the jury can convict on a majority verdict. In some cases, such as the trial of Abdelbaset al-Megrahi and Lamin Khalifah Fhimah for the bombing of Pan Am Flight 103, a trial can be heard by a bench of judges alone; sitting without a jury. As an appeal court the hearings are always without a jury, with two judges sitting to hear an appeal against sentence, and three judges sit to hear an appeal against conviction.
