# Senate of Thailand

The Senate of Thailand is the upper house of the National Assembly of Thailand, Thailand's legislative branch. In accordance with the 2017 constitution of Thailand, the Senate is a non-partisan legislative chamber, composed of 200 members – all are indirectly voted by the candidates from 20 professional and social groups. Senators serve five year terms in office. However, in practice, the chamber is split into factions with political ties.
Thailand has not always had a senate. Some constitutions provided for senate, with senators being fully appointed, half-elected, and fully elected. Most recently, during 2014 and 2019, the senate was abolished and replaced by unicameral National Legislative Assembly.

## History

The idea of bicameralism first permeated Thai politics with the Constitution of 1946, when the government of Pridi Banomyong introduced a Senate modelled on the British House of Lords. For the first time, an upper house came into existence in Thailand. The Senate was to be fully elected, however, the elections would be indirect, as the House of Representatives would elect the senators, for six-year terms. The 1946 Constitution was soon abrogated in a military coup. Subsequent constitutions saw only occasional bicameralism, and when it did exist, the Senate was always filled with appointees from the military and the elite. The 1997 constitution saw a return to a fully elected Senate. That constitution was abrogated after the 2006 coup, and replaced with one calling for a half-elected/half-appointed Senate. The 2007 Constitution was itself repealed in 2018 following the 2014 coup, and replaced with a new one which provided for a fully appointed Senate.
