Hobbes’s notion of representative government is one where the representative expresses the will of his constituents in the sense of having power of attorney over their choices. Whatever the representative does is seen as identical to what all of his constituents unanimously decide for themselves. As corollaries:
1.) All former covenants or governments are void. There is no sovereign power to enforce them, and nothing is more vain than a contract with no power to enforce it.
2.) The representative (sovereign) cannot injure a constituent since whatever he does to them is willed by them.
3.) The representative can decide all controversies among his citizens since, whatever he says they will, they do in fact will.
