Conference of State Governors (Austria)
The Conference of State Governors (German: Landeshauptleutekonferenz) is an informal – not provided for in the Constitution of Austria – meeting of the nine state governors. Alongside the Federal Council, the Austrian upper house, it is the second most important body for co-operation between the states as well as for federalism in the Austrian political system (in the modern Austria).
