Over the past two decades, there have been significant legal developments aimed at securing and enhancing the participation of vulnerable witnesses in criminal trials. Yet, there remains relatively little regard for the fact that many defendants, including those who are not deemed to be vulnerable, are unable to participate in criminal proceedings in a meaningful sense. This paper aims to address two questions. First, why should defendants have participatory rights and be capable of meaningful participation in criminal proceedings? Second, why has it proven so difficult to attain meaningful participation of defendants? It is contended that barriers to meaningful communication between the defendant and the court could be dismantled without great difficulty, but continue to exist because due regard is not given to the normative rationales for participatory rights and defendant participation.
