Indian High Courts: Each state has a High Court. It is the highest judicial organ of the state. However, there can be a common high Court like Punjab. There are 24 High Courts at the state and union territory level of India, which together with the Supreme court of India at the national level, comprise judicial system.

Each High Court has jurisdiction over a state, a union territory or a group of states and union territories. Below mentioned High Courts are a hierarchy of subordinate courts such as the civil courts, family courts, criminal courts and various other district courts. High Courts are instituted as constitutional courts under Part VI, Chapter V, Article 214 of the Indian Constitution.
The High Courts are the principal civil courts of original jurisdiction in each state and union territory. However, a High Court exercises its original civil and criminal jurisdiction only if the subordinate courts are not authorized by law to try such matters for lack of pecuniary, territorial jurisdiction. High courts may also enjoy original jurisdiction in certain matters if so designated specifically in a state or federal law. Consists of chief justice & other such judge as appointed by the president.
The Constitution, unlike in the case of the Supreme Court, does not fix any maximum number of a judge for a High Court (Allahabad High Court has 37 Judges while J& K High Court has only 5). A Judge of a high court be transferred to another High Court without his consent by the president. In this, the chief justice of India is also consulted. The opinion provided by him shall have primacy and is binding on the president. However, the work of most High Courts primarily consists of appeals from lower courts and writ petitions in terms of Article 226 of the constitution. Write jurisdiction is also the original jurisdiction of High Court. The precise territorial jurisdiction of each High Court varies. The appeal order is the following: tehsil-kotwali-criminal/civil courts-district-high court-Supreme Court.
