The legislative process

Bills come from Congress, the executive, regional governments or citizens. A single chamber debates in committee and plenary; a second vote is required unless exempted. The President may observe a bill, and Congress insists by absolute majority. Constitutional amendment needs an absolute majority in two successive ordinary legislatures, or a two-thirds vote plus referendum.
