A very important part of Austria's canon of constitutional civil liberties thus originated as an imperatorial edict predating the current Constitution of Austria by roughly fifty years, the reason being that the framers of the Constitution in 1920 could not agree on a set of civil liberties to include in the constitution proper: as a lowest common denominator, they resorted to this Basic Law of 1867. Since then, other civil liberties have been set out in other constitutional laws, and Austria is party to the European Convention of Human Rights, which, too, has been implemented as a directly applicable constitutional law in Austria.
