The law maintains, rather than challenges, the powers that be – or so it is commonly thought. In ‘Rackets and Spirit,’ a little known and untranslated essay, Max Horkheimer complicates this notion by attributing to law a ‘force of resistance’. He contends that, under certain conditions, the legal process develops a logic of its own, one that can become disjointed from the rationale of power. In this Critical Reflection, I look closely at the paragraph in which Horkheimer introduces the notion of a ‘force of resistance’. I argue that Horkheimer develops a theme that he and Theodor W. Adorno return to in the Dialectic of Enlightenment: the spiritual instruments of domination, among them law, have the potential to turn against domination. At the same time, Horkheimer is clear that law does not resist automatically: it takes human agents to put the legal sphere into opposition to the political sphere. I illustrate this thought with respect to the recent history of federal abortion rights in the United States.
