Semi-Salic succession was introduced in 1842. (I suppose it was repealed in 1993.) The article below describes some of the history of the Liechtenstein house laws.
Art. 3 – Verfassungskommentar
The usage of semi-Salic succession was widespread in German house laws and constitutions during the 19th century. The house of Nassau, which now reigns over the grand duchy of Luxembourg, also stipulated semi-Salic succession in its house laws until 2012.
If you refer to the house law of 1993, which remains applicable today, you can read a full English translation of it here:
