A basic law is either a codified constitution, or in countries with uncodified constitutions, a law designed to have the effect of a constitution. 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.
