A formal model is proposed of argumentation with burdens and standards of proof, overcoming shortcomings of earlier work. The model is based on a distinction between default and inverted burdens of proof. This distinction is formalised by adapting the definition of defeat of the ASPIC+ framework for structured argumentation. Since ASPIC+ generates abstract argumentation frameworks, the model is thus given a Dungean semantics. It is shown to adequately capture shifting proof burdens as well as Carneades’ definitions of proof standards.
