According to model-theoretic inferentialism (and despite proof-theoretic semantics and model-theoretic semantics), both proof-theoretic and model-theoretic notions play a role in the meaning of logical constants. However, proof-theoretic notions have a more fundamental role compared to model-theoretic notions, so that the semantics and its structure are determined by the proof-theoretic notions. In other words, in proof-theoretic inferentialism, we follow a method by which we can read the semantics from the proof theory. This approach is related to the problem of categoricity and Carnap's non-normal models for proof systems. In this paper we investigate this issue for two paraconsistent logics, mbC and LP. We show that while multi-succedent sequent calculi are categorical for mbC, they are not for LP. That latter has non-normal models. We argue that for the latter we cannot easily read the semantics from the proof theory, except at the cost of distorting the notion of logical consequence.
