Explanation

Please note: Only the Dutch-language version of the Constitution has legal effect. 

The Houses (including in Joint Session) may only convene if more than half of the members are present.

Decisions are taken by a majority vote. Sometimes a two-thirds majority is required for a decision, but only if this is stipulated in the Constitution.

Members vote without mandate. This means that they must be free to vote. Members of Parliament may consult with others (within and outside Parliament), but may not take decisions 'on the orders of others'.
