Jurisdiction and the Moral Impact Theory of Law.

Positivists and interpretivists (Dworkinians) might accept that conceptual facts about the law—facts about the content of the concept of law—can obtain in the absence of communities with law practices. But they would deny that legal facts can obtain in such communities' absence. Under the moral impact theory, by contrast, legal facts can precede all communities with law practices. I identify a set of legal facts in private international law— the law of jurisdiction —that concerns when a community's law practices can, and cannot, have the legal effects that the practices claim to have. This law is noncommunitarian, in the sense that it precedes the communities to which it applies. In this law's light, the legal effects of communities' law practices are legally coordinated (or, at the very least, can be shown to legally conflict). Although interest in, and even commitment to, a noncommunitarian law of jurisdiction has receded among private international law theorists, I argue that some well-placed questions can elicit from all of us a commitment to this law. And this commitment is a reason to believe that the moral impact theory is correct. [ABSTRACT FROM AUTHOR]
