Basic Law

A basic law is a law designed to have the effect of a constitution, but is not named as one to indicate its provisional or inferior status. The term basic law is used in some places as an alternative to "constitution" and may be intended as a temporary but necessary measure, until the formal enactment of a constitution. "Basic law" is sometimes used to avoid it being taken to be, like a constitution, "the highest law". There may be various reasons, such as religion, for this.
