Members of the Ziu propose legislation by first presenting it in the Hopper for discussion and then submitting it to the Secretary of State to be put in the clark so the legislation can be voted upon. Most bills require a majority of both houses of the Ziu to pass, whereas amendments to the Organic Law require the support of 2/3rds of the Cosa and a majority (or in some cases a 2/3rds supermajority) of the Senäts.
The King is also a member, ex officio, of the Ziu, as his approval of bills is an integral part of the passage of legislation into law. Being a member of the Ziu also affords the King the ability to introduce bills thereto, although in practice he seldom exercises this power.
Legislative actions of the Ziu are codified in the Digest of Laws.
