abstract The paper considers what (if anything) can justify that a utopian community or a micro-society makes an exception to the general rules of society for itself. The discussion evolves around the Danish case of Christiania. Three moral theories, to wit Kantian constructivism, rule-consequentialism and act-consequentialism, are applied to the case at hand. The aim is to test whether the exceptions in question are unjust or in other ways morally problematic. The two former theories appear to deny the justice of Christiania. The relevant exceptions are unacceptable according to those two moral perspectives. Act-consequentialism, however, seems to endorse the case of Christiania, including the exceptions pertaining to it. While the latter theory is often thought to conflict with widely shared reflective moral convictions, in this case it might square with at least an important pragmatic layer of Danish public culture.
