The Cosa is the lower house of the Talossan Ziu. (The upper house is the Senäts.)
The Cosa consists of 200 seats, all of which are contested at each general election. In a popular vote, each citizen casts a ballot for the political party of his or her choice. Each party then assigns representatives — called “Members of the Cosa” (or “MCs”) — to hold the seats won by the party. MCs hold office until the next general election; general elections take place at roughly 8 to 9 -month intervals.
