The Constitution of Royal Kingdom of Thailand B.E. 2540 (1997) has determined to establish the courts to perform the duties in considering the cases by dividing the courts into 4 categories namely
- The Constitution Court is a court which has a jurisdiction in making a consideration and decision of the problems which concern the constitutional laws.
- The Administrative Court is a court which has a jurisdiction in making a consideration and judgment of the cases which concern the administrative agreements and the administrative orders.
- The Military Court is a court which has a jurisdiction in making a consideration and judgment of the military criminal cases and other cases provided by law.

I The Constitution Court is a judicial body under the Constitution which does not consider or adjudge the general cases but the Constitution Court has a jurisdiction in making consideration and decision of the cases which have legal problems concerning the constitution which is the supreme law of the country. The main duty of the Constitution Court is to supervise the laws not to contradict or conflict with the constitution in order to uphold the status of the constitution as the supreme law of the country.
The purposes of the supervision of the laws not to contradict of conflict with the constitution are as follows :-
1) For the benefits of the general public by not allowing any enacting of the law which affects the right and freedom of the people which the constitution has recognized.
2) For the benefits of governing of the country by means of maintaining the balance of duty performance of each judicial body as appeared in the constitution which is the power balancing process amongst the different bodies under the provisions of the constitution in the democracy.
3) For a protection of the constitution which is the fundamental law in governing the country in order to uphold the status of the constitution as the supreme law. When the provision of any law has a statement or intention which contradicts or conflicts with the constitution, a supervision must be made by making a decision that such law shall not be enforceable.
