The Parliament is bicameral, thus consists of an upper- and a lower house, the House of Senate and House of Delegates respectively. The number of seats within the House of Delegates is fixed, per the Parliament Act, however the number of seats within the House of Senate is always expanding, as former (and current) presidents and cabinet members are also and remain part of the House for life. However, because of this, the power of votes from the House of Senate weigh less than that of the much stronger and democratic House of Delegates. Senators are appointed by the current President with advice from the House of Delegates, and unofficially customary advice from his current Prime Minister.
