Explanation:

Subordinate Courts

• The state judiciary consists of a high court and a hierarchy of subordinate courts, also known as lower courts. 
• The subordinate courts are so called because of their subordination to the state high court. They function below and under the high court at district and lower levels.

Articles 233 to 237 in Part VI of the Constitution make the following provisions to regulate the organization of subordinate courts and to ensure their independence from the executive.
Appointment of District Judges: The appointment, posting and promotion of district judges in a state are made by the governor of the state in consultation with the high court. A person to be appointed as district judge should have the following qualifications:

• He should not already be in the service of the Central or the state government.
• He should have been an advocate or a pleader for seven years.
• He should be recommended by the high court for appointment

Appointment of other Judges: Appointment of persons (other than district judges) to the judicial service of a state are made by the governor of the state after consultation with the State Public Service Commission and the high court.
