In the center of interests of the late Derrida is justice, which is becoming more and more relevant in the context of global world changes. In 1989, Derrida formulated the thesis that deconstruction is a discourse about justice.
Derrida opposed law (that is, legal systems) with justice. Law (law, justice) is subject to deconstruction. The possibility of deconstruction of law is a condition of historical development in the political sphere; the process of this deconstruction strives for justice. Law is deconstructed because it is a construction that does not justify itself, but always refers to something else.
The norms of law for Derrida are proclaimed to be universal, but in reality they operate in a limited area. Derrida posed the question: who is the owner of rights - a person or a citizen? The assignment of rights to a citizen refers to external mechanisms: the city, the state. Thus, a person as such is deprived of rights. Derrida analyzes the American Declaration of Independence. The text was created by one person, signed by a group of people who represent the people. In turn, the people refer to God. Derrida raises the question of who are represented, that is, the people. As a result, it turns out that the text of the Declaration refers to God..
Justice, unlike law, cannot be deconstructed, since it is not a construction, but refers to a unique event, even insanity. Justice is indefinite; in a certain sense, justice does not exist. Justice is not an idea (eidos, model or ideal), but rather an impossibility. It is something that gives us an impulse to improve the law through deconstruction.
