The term basic law is used in some places as an alternative to "constitution", implying it is a temporary but necessary measure without formal enactment of constitution. A basic law is either a codified constitution, or in countries with uncodified constitutions, a law given to have constitution powers and effect. The name is usually used to imply an interim or transitory nature, or avoid attempting a claim to being "the highest law", often for religious reasons. In West Germany the term "Basic Law" (Grundgesetz) was used to indicate that the Basic Law was provisional until the ultimate reunification of Germany. But in 1990 no new constitution was adopted and instead the Basic Law was adopted throughout the entire German territory. Basic law is entrenched in that it overrides ordinary 'statute law' passed by the legislature.
