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.

[4][5] 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.

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 200-person Senate is selected by the candidates from represent twenty professional and social groups: bureaucrats, teachers, judges, farmers, and private companies.

[citation needed] Even though the chamber is mandated to be nonpartisan, many media and analysts have identified political factions: Note: All of these numbers may not be 100% accurate.

If the candidate was a member of a local administration or a Minister he must have left his post for a period of at least five years before being eligible.

The election was done by secret ballot, after a resolution finalizing the selection the name was submitted to the king for formal appointment.
