The basis of structuring of district courts in India is mainly depending upon the discretion of the state governments or the union territories. The structure of those courts are mainly made considering several factors like the number of cases, distribution of population, etc. Depending upon those factors the state government takes the decision of numbers of District Courts to be in operation for single district or clubbing together different adjacent districts.
Normally these types of courts exercise their power of juridical service in district level. These courts are covered by the administrative power of the High Courts under which the district courts are covered. The judgments of the district courts are subject to review to the appellate jurisdiction of the respective high court.
The district courts are mainly run by the state government appointed district judges. There are additional district judges and assistant district judges who are there to share the additional load of the proceedings of District Courts. These additional district judges have equal power like the district judges for the jurisdiction area of any city which has got the status of metropolitan area as conferred by the state government. These district courts have the additional jurisdictional authority of appeal handling over the subordinate courts which are there in the same district specifically in the domain of civil and criminal affairs.
