The deconstruction of the Constitution is an expression of extra-systemic dissensus directed against the current political order and strongly antagonising political actors within the state and in relations with the EU. In the article, we argue that the political changes in Poland do not herald a new type of constitutionalism, but rather constitute its deconstruction. The main actor subject to deconstruction is the Constitutional Tribunal (CT). Consequently, the deconstructed CT became an important instrument for further deconstruction of the Constitution, notably evident in the dispute over the primacy of the Constitution over European law. The deconstruction of the Constitution has its roots in the lack of sociological legitimacy of the Polish Constitution and its portrayal by certain right-wing political parties as failing to establish a level playing field in the political game.
