In Thailand, a kingdom that has had a constitution since the initial attempt to overthrow the absolute monarchy system in 1932, the rule of law has been more of a principle than actual practice.[citation needed] Ancient prejudices and political bias have been present in the three branches of government with each of their foundings, and justice has been processed formally according to the law but in fact more closely aligned with royalist principles that are still advocated in the 21st century.[citation needed] In November 2013, Thailand faced still further threats to the rule of law when the executive branch rejected a supreme court decision over how to select senators.[citation needed]

In Thailand, what branch of government rejected a proposal for senator selection?
