On December 10, 1932, the first permanent constitution of Thailand was promulgated. It differed from the former provisional constitution in many aspects such as:

1. It changed the country's administration into a Parliamentary system. The constitution of 1932 specified that the King who was Head of State did not hold any political responsibilities and would exercise his executive power through the cabinet appointed by him. The cabinet was responsible to the House of Representatives for the country's administration, which had power to cast a vote of no confidence that could dismiss the cabinet. The Parliamentary system allowed the parliament, which had legislative power to control the administration of the cabinet.
2. Since the constitution used a parliamentary system to control the administration, it provided a mechanism of checks and balances between the legislative and executive branches. That is, although the legislative branch was empowered to control the cabinet which was the executive branch, the cabinet with the king's consent was also able to dissolve the Parliament if it conducted itself in a way that could cause danger or disadvantage to the national interest. Dissolution of parliament meant the dismissal of elected representatives and returned power to the people for reelection.
3. Regarding the King, the constitution stated that the King was in a respected and unimpeachable position, which meant that no one could bring any charges against the King under any circumstances and that the King did not hold any political responsibility. This was different from the provisional constitution which gave the House of Representatives the power to investigate a case when there was a charge laid against the King. Criminal charges laid against the King, according to the provisional constitution, were not considered by the courts but by the House of Representatives. The new permanent constitution of 1932 abrogated that power of the House of Representatives and made the King immune from any charges.
4. Regarding the House of Representatives, there were no major changes. There were only 2 periods of the House as stated in the new constitution.

The first period dated from the promulgation of the provisional constitution of 1932, consisting of 2 groups of members: members by public election and members by the King's appointment. The constitution did not forbid the appointment of these two groups of members from permanent government officials.

The second period was when over half of electors finished their primary education or not later than 10 years from the promulgation of provisional constitution. The House of Representatives would be comprised of only one type of members. However, the amended constitution concerning the interim provision of 1942 extended the second period to 20 years from the first day of promulgation of the provisional constitution.

5. The King exercised his executive power through an appointed cabinet who would be responsible to the National Assembly in general and to ministers individually. Ministers were in charge of ministry affairs. The House of Representatives did not have the power to appoint or dismiss ministers like the People's Committee except that they could initiate a general debate on a no-confidence vote which could result in the forced resignation of the whole cabinet. The cabinet was also responsible for using its executive power on the King's behalf and possessed governing power of state. All the old forms of ministries were abolished and new ones were established.
