Parliament appoints the President. Bills can be presented by the President, a member of the government, or a member of Parliament. Legislative texts accepted by Parliament and by the President, are called laws. They are valid in the whole territory of Flanders. Flemish laws can't have, under any circumstance, retroactive power.
Parliament can only accept a law or another decision if it is voted clause by clause.
Parliament can only accept a clause when a majority of the present members of Parliament votes in favour of that clause. Parliament can't vote validly if not at least three quarters of its members participates in the voting. The President can veto a law if that law is in contradiction with the Constitution. A presidential veto always has to be accompanied by an argumentation based on a violation of the Constitution. The government or the President can always demand a referendum about a bill or an ammendment on the Constitution.
