Opponents of compulsory voting often allege that it violates a ‘right not to vote’. This paper seeks to clarify and defend such a right against its critics. First, I propose that this right must be understood as a Hohfeldian claim against being compelled to vote, rather than as a mere privilege to abstain. So construed, the right not to vote is compatible with a duty to vote, so arguments for a duty to vote do not refute the existence of such a right. The right against compulsion is most easily defended within a liberal framework, hence its critics often appeal instead to a republican conception of freedom. In the latter part of the paper, I argue that even these republican arguments are inconclusive. Even non-dominating interference still conditions freedom, which may require justification. Further, citizens can live up to republican ideals, so long as they are vigilant; they need not actually vote. Thus, republican arguments fail to refute a right not to vote.
