Article 85 provides that the King's constitutional powers are hereditary through the direct, natural and legitimate descent from King Leopold I, by order of primogeniture. However, in Title IX, which contains certain transitional provisions, there is a clause that stipulates that Article 85 in its current shall be applicable for the first time on the descent of King Albert II, which means that the female offspring of King Albert II and later monarchs are in the line of succession to the Belgian throne, whereas the female offspring of all previous Belgian kings are excluded from the throne. This transitional clause was inserted to regulate the transition from the Salic law, which barred women and their descendants from the throne and was in effect until 1991.
