Abstract
We present evidence for the existence of `responsibility voids' in committee decision-making, that is, the existence of situations where no member of a committee can individually be held morally responsible for the outcome. We analyse three types of reasons (causal, normative and epistemic) for the emergence of responsibility voids, and show that each of them can occur in committees. But the conditions for these voids are so restrictive as to reduce the philosophical or institutional significance they might be thought to possess
