The judicial use of foreign law in constitutional cases is often unsatisfactorily explained in terms of persuasive authority, judicial learning or judicial dialogue. In this article, I argue that the central case of the judicial use of foreign law involves judges treating foreign case law as theoretically, rather than practically, authoritative. The justification for this approach lies in how case law emerges from a process that is structured in such a way that its outcomes deserve respect. There is, in contrast, no justification for any attempt on the part of judges to treat constitutional cases as an opportunity for interjurisdictional judicial dialogue.
