"Polish parliament" (Swedish and Norwegian: Polsk riksdag; Danish: Polsk rigsdag; German: Polnischer Reichstag; Dutch: Poolse landdag; Polish: Polski parlament; Finnish: Puolalainen parlamentti) is an expression referring to the historical Polish parliaments (Sejm walny). It implies chaos and general disorder, and that no real decision can be reached during sessions.
Origin
Every single member of the Polish parliament during the 17th and 18th century had an absolute veto (Latin: liberum veto), meaning that decisions could often only be made with great difficulty. Originally, the procedure was used for technical issues such as points of order, but came to be abused. Today, the expression is mostly used to describe an assembly that is too easy for minorities or individuals to disrupt and/or has too many parties present for meaningful and orderly debate and decision-making to take place.
The expression is found in several European languages, including all Scandinavian languages.
