Prophylactic Rules and State Constitutionalism 1 Arthur Leavens ABSTRACT When the post-Warren Supreme Court began trimming back individual rights, some state courts responded by interpreting analogous or cognate state- constitutional provisions to find broader protections, prompting a vigorous debate concerning the legitimacy and interpretive methodology of such state constitutionalism. How can two constitutional provisions, sharing the same language and history, mean different things? This article looks at that question in the context of so-called prophylactic rules—those specific constitutional rules meant to guide the implementation of broader federal constitutional principles. Miranda’s warning-and-waiver construct is probably the best known prophylactic rule, but such rules abound, particularly in criminal procedure. This article argues that even if states ought to defer to the Supreme Court concerning the meaning of cognate constitutional provisions, such deference is not required in considering the reach of prophylactic rules.
