Does Formal Rank Matter?

Abstract

As is well known, different countries may have a different attitude toward the formal rank of international human rights law in domestic legal order. In those countries that qualify the ratified international human rights law merely as statute, the formal rank of international human rights law is often used as an argument against the binding force of international human rights law on domestic constitutional law. Through a comparative analysis between Germany and Taiwan, though, this paper shows that, despite similar determinations on the formal rank of international (human rights) law, the German and the Taiwanese Constitutional Courts have developed quite different views on the normative significance of international human rights law to their domestic constitutional orders. The different constitutional practices in Germany and Taiwan thus not only reflect Taiwan’s unique international status, but also indicate that the formal rank of international human rights law does not have much to do with its normative binding force on domestic constitutional law. Those who use formal rank as an argument against the binding force of international human rights law on constitutional law presuppose the absolute dichotomy of international and domestic law and thereby overlook the potential compatibility between international human rights law and constitutional law. From a human rights perspective, I argue that international human rights law should not be regarded as an “external” law, but rather as a framework order which delegates domestic constitutional orders to concretize international human rights law according to their own needs or interests so as to fulfill their international task of human rights protection on national level. Viewed this way, the determination on the formal rank of international human rights law in domestic legal order matters only because it has to do with the determination of a certain constitutional order on the way in which it concretizes international human rights law.
