 All bills had to pass the "Sejm" or "Seimas" (Parliament) by unanimous consent, and if any legislator voted "nay" on anything, this not only vetoed that bill but also dissolved that legislative session itself.The concept originated in the idea of "Polish democracy" as any Pole of noble extraction was considered as good as any other, no matter how low or high his material condition might be.It was never exercised, however, under the rule of the strong Polish royal dynasties, which came to an end in the mid-17th century.
