The effectiveness of the proportionality principle in regulating the limits of emergency federal intervention: a comparative study

Abstract

Emergency federal intervention is considered one of the most serious exceptional powers granted to the federal government, given its potential to infringe upon the structural constitutional principles upon which the federal state is based, particularly the principle of the autonomy of federal units and the balanced distribution of powers between them and the federal authority. In this context, the principle of proportionality emerges as the legal tool for evaluating the legitimacy of exercising this power. However, most comparative constitutional systems have applied the proportionality test within the framework of balancing exceptional measures with the severity of the existing threat and its impact on rights and freedoms, without systematically extending this to testing the proportionality between the means of emergency federal intervention and the severity of the existing threat and its impact on the structural constitutional principles of the federal system. Based on this research gap, this study adopts a comparative analytical methodology, guided by the elements of the three-part proportionality test, to examine and analyze the principle of proportionality in three federal systems where the legislator's philosophy in distributing powers and the degree of autonomy of federal units differs (the United States of America, India, and Iraq). The study concluded that they share a common characteristic: the absence of a systematic, organized, and explicit proportionality test. In the United States, proportionality appears fragmented and without a structured judicial proportionality test. In India, its application in the context of emergency federal intervention remained implicit and limited due to the centralizing tendencies of the constitutional system and legislative restrictions on judicial oversight. In Iraq, the absence of federal legislation following the entry into force of the constitution to regulate emergency federal intervention, as well as the lack of practical applications of this power, prevented the existence of judicial applications or the development of effective oversight of proportionality, thus keeping this principle within its theoretical scope without practical application. Hence, this study came to contribute to the development of previous traditional jurisprudential studies by expanding the scope of the proportionality principle to include the protection of the structural constitutional principles of the federal system, and it proposes activating the three-part test of proportionality in this field, since the effects of federal intervention are not limited to individual legal positions only, but extend to the federal constitutional structure.
