["\nAbstract\nThis article examines how authoritarian contenders use law to advance an agenda geared to exclusive state power in light of a paradigmatic case: the National Socialists’ takeover of the German state apparatus in spring 1933. This case highlights two ways in which an office holder is able to expand his power in an authoritarian fashion through legal dispositions. A conjunctural use of law for authoritarian purposes draws on legal statutes to undercut the political capacity of opponents and competitors, hollow out institutional checks, and crucially hamper civil freedoms. Taking advantage of constitutional provisions that make institutional subversion from within possible (‘constitutional Trojan horses’), a structural use of legal statutes reorders the power structure by reallocating decisional rights. In both cases, law serves as a weapon against the rule of law. These considerations raise the question of the standards by which we are to judge the legality of such acts. Contemporary instances of democratic backsliding are cases in point.\n", "Journal of Law and Society, Volume 47, Issue S1, Page S164-S186, October 2020. "]
