Thus it is said that there is no law of succession to the throne in Thailand, but in fact it appears there is a law of sorts. The critical rule is that the successor to the throne must be of royal family (jao) (that is, from the group which descended the steps from the sky to come and govern according to the instruction of the sky god or thaen in Black Thai language). But the Thai law is not detailed to the extent of specifying that the eldest son (or the last
child) must succeed. At the same time, there is no practice of ranking those with rights of succession to the throne according to any principle, as was introduced later by copying an English practice.
