 In its current form, the court goes back to the Pillersdorf Constitution of 1848.The court survived the persistent political unrest and periodic constitutional upheavals of the 1850s and 1860s, the Austro-Hungarian Compromise of 1867, and the collapse of the Empire at the end of World War I.Except for a change of name, it was retained unaltered both by the provisional government of the emerging First Austrian Republic in 1918 and by the Constitution of 1920.
