Abstract
A central element of Robert Alexy's theory of constitutional rights is his principle of proportionality. This includes analytically an understanding of basic rights as principle, which is supposed to resolve both the tension between democracy and constitutional court and the problem of collision between public interest and basic rights. The article begins with an outline of this theory and the objections which have been raised by numerous domestic authors. It then takes up the principle of proportionality from the global point of view.
