Causal exclusion without physical completeness and no overdetermination

Hitchcock (2012) demonstrated that the validity of causal exclusion arguments as well as the plausibility of several of their premises hinges on the specific theory of causation endorsed. In this paper I show that the validity of causal exclusion arguments if represented within the theory of causal Bayes nets the way Gebharter (2015) suggests actually requires much weaker premises than the ones which are typically assumed. In particular, neither completeness of the physical domain nor the no overdetermination assumption is required.
