The voluntary plan, therefore, when tried in this easy form is inconsistent with the extrinsic independence as well as with the inherent moderation of a Parliament⁠—two of the conditions which, as we have seen, are essential to the bare possibility of Parliamentary government. The same objections, as is inevitable, adhere to that principle under its more complicated forms. It is in vain to pile detail on detail when the objection is one of first principle. If the above reasoning be sound, compulsory constituencies are necessary, voluntary constituencies destructive; the optional transferability of votes is not a salutary aid, but a ruinous innovation.
