A lower house is the lower chamber of a bicameral legislature, where the other chamber is the upper house.
[1] Although styled as "below" the upper house, in many legislatures worldwide, the lower house has come to wield more power or otherwise exert significant political influence.
In comparison with the upper house, lower houses frequently display certain characteristics (though they vary by jurisdiction).
It is a widespread practice for revenue (appropriation) bills to originate in the lower house.
A notable exception to this is the West Virginia House of Delegates in the United States, which allows revenue bills to originate from either house.
