With the exception of Great Britain and, for the present at least, of Israel, probably all states possess a written constitution, systematically arranged and with set articles. Another term often used for constitution is basic or fundamental law, since the constitution provides a foundation and framework for the other regulations and norms which form the legal system of the country. In most countries, in fact, the constitution is made in such a way that it is more difficult to change than are ordinary laws; for instance, a set majority in parliament may be required for amendment, or the lapse of a certain amount of time, perhaps there must be an intervening parliamentary election between the proposal and adoption, or an amendment must be ratified by popular vote, etc. An exception to this is the procedure in New Zealand, where although the constitution is systematically arranged, no attempt is made to ensure the stability of it by means of such technical procedures; it can be changed in the same way as an ordinary law.
