India has one of the oldest legal systems in the world. The Constitution of India is the supreme law of the country; it gives due recognition to statutes, case laws, and customary laws consistent with its dispensations. There is also a vast body of laws known as subordinate legislation in the form of rules, regulations, and bylaws made by the Central and State Governments and local authorities.
The Constitution has generally provided for a single integrated system of courts to administer both union and state laws. As mentioned previously, the judiciary is divided into various levels, with the courts forming a strict hierarchy of importance: the Supreme Court of India, High Courts (of respective states/groups of states), District Courts, followed by other subordinate courts.
