  It was also argued, notably by Jarrett 1984 and 1989 and Shimony 1984, that in contrast to violations of OI, violations of PI may give rise (at least in principle) to superluminal signaling. Indeed, as is not difficult to see from section 7.1, in theories that satisfy λ-independence there is an asymmetry between failures of PI and failures of OI with respect to superluminal signaling: whereas λ-distribution and the failure of PI are sufficient conditions for the in-principle possibility of superluminal signaling, λ-distribution and the failure of OI are not. Thus, the prospects of superluminal signaling look better in parameter-dependent theories, i.e., theories that violate PI. Yet, as we have seen in section 7.2.1, if the Bohmian quantum-equilbrium distribution obtains, then Bohm's theory, the paradigm of parameter dependent theories, prohibits superluminal signaling. And if this distribution is obtained as a matter of law, then Bohm's theory prohibits superluminal signaling even in theory. Furthermore, as we remarked in section 7.1, if the in-principle possibility of violating λ-independence is not excluded, superluminal signaling may exist in theories that satisfy PI and violate OI. In fact, as section 7.4 seems to suggest, the possibility of superluminal signaling in theories that satisfy PI but violate OI cannot be discounted even when λ-independence is impossible.
