The Indian Constitution has established an integrated judicial system with the Supreme Court at the top and the high court’s below it. 

• Under a high court (and below the state level), there is a hierarchy of subordinate courts, that is, district courts and other lower courts.  

• This single system of courts, adopted from the Government of India Act of 1935, enforces both Central laws as well as the state laws.
