Polish parliament (Swedish and Norwegian Polsk riksdag, Danish Polsk rigsdag, German Polnischer Reichstag) is an expression referring to the historical Polish parliaments.[1] It implies chaos and general disorder, and that no real decision can be reached during sessions. The origin is that any single member of the Polish parliament during the 17th and 18th century had an absolute veto (lat. liberum veto), so that complete consensus—which could be attained only with great difficulty—was required for every issue. Originally, the procedure was used for points of order and similar technical issues, however, it was later abused. Today the expression is mostly used to describe a situation where too many parties are present in a legislative assembly for meaningful and orderly debate and decision-making to take place.
The expression is found in several European languages, including all the Scandinavian languages.
