Since 1945, the assembly has only met to swear the elected President of Austria into office.
This provision however did not become effective until 1951, when Theodor Körner became the first president directly elected by the Austrian people.
It recently met at the inauguration of Alexander Van der Bellen's second term as Austrian President on 26 January 2023.
[1] In theory, the Federal Assembly also functions as an instrument of checks and balances; upon request by a two-thirds majority of the National Council, it may impeach the president before the Constitutional Court, or upon request by a two-thirds majority in the National Council decide on a referendum to have the president removed from office.
The assent of the Assembly would also be required for the president's immunity against criminal prosecution to be withdrawn.
