If the legislative, or any part of it, be made up of representatives chosen for that time by the people, which afterwards return into the ordinary state of subjects, and have no share in the legislature but upon a new choice, this power of chusing must also be exercised by the people, either at certain appointed seasons, or else when they are summoned to it; and in this latter case the power of convoking the legislative is ordinarily placed in the executive, and has one of these two limitations in respect of time: that either the original constitution requires their assembling and acting at certain intervals, and then the executive power does nothing but ministerially issue directions for their electing and assembling, according to due forms; or else it is left to his prudence to call them by new elections, when the occasions or exigencies of the public require the amendment of old, or making of new laws, or the redress or prevention of any inconveniencies, that lie on, or threaten the people.

如果立法权力或它的任何部分，由人们选举的代表组成，在需要立法的时候集会，法律制定之后仍回归臣民的普通状态，除非重新当选，不再享有任何立法权力，那么选举的权力也应由人们在一确定的时间或当他们被召集时行使；在后一种情况下，召集立法的权力通常交给执行权力，在时间上受以下二者限制：或由最初的宪法规定的每隔一段时间之后就集会并制定法律，执行权力仅仅以政府的名义发布依据正当的形式进行议员选举和集会的指令；或当公共领域出现紧急情况，要求修订旧法律，或制定新法律，或矫正和预防任何存在和将威胁人们的不便干扰，这留给执行权力的审慎来决定，通过新的选举来召集立法议员。
