Liberum Veto
From Free net encyclopedia
Liberum Veto is a parliamentary voting system used in Poland (the 17th and 18th century), by which any member of parliament could veto (latin: Liberum Veto) a law with a single vote.
In other words all resolutions had to be carried unanimously (governing by unanimous consent).
The phrase Liberum Veto comes from Latin: liberum, unrestricted, and veto, "I forbid".
