  • Barczentewicz, 'Who Made the United States Constitution?' (2015)
    This paper answers the question who made the United States Constitution from the perspective of general jurisprudence aided by historical evidence. On my view, to make a constitution qua law one must satisfy two conditions: (1) act intending to make a constitution while viewing oneself as having authority to do so and (2) be de facto authoritative in making a constitution. HLA Hart’s concepts of secondary rules of recognition and of change figure prominently in my account. Beginning with a sketch of the historical process of the making of the Constitution, I then identify the agents involved in it. I observe that on any plausible account the making was a cooperative process involving groups of people and thus I consider the issue of group agency, arguing that groups can act and have intentions when certain conditions are satisfied. Several candidates for the Constitution’s maker are evaluated in this paper: “We the People”, “the Drafters”, “the Ratifiers”, “the Great Men”, the states and the peoples of the states. The historical material available does not allow for a decisive answer to the question who was the maker. However, I conclude that based on the available evidence it is most compelling to view the thirteen state groups of the Ratifiers as the makers of the Constitution, because they viewed themselves as acting to establish the Constitution with authority delegated by the people of their states and because their act of ratification was, in fact, recognized as establishing the Constitution as law.
  • Barczentewicz, '‘Constitutional Statutes’ Still Alive' (2014) 130 Law Quarterly Review 557 [Case Note]
    In R. (Buckinghamshire CC) v Secretary of State for Transport [2014] UKSC 3; [2014] 1 W.L.R. 324 (HS2) the Supreme Court has provided a good reason to think that the idea of a hierarchy of statutes within the legal system of the United Kingdom is still alive, despite the fact that some commentators have already heralded its early demise.
