From the Declaration of Independence:
He has refused for a long time, after such dissolutions, to cause others to be elected; whereby the Legislative powers, incapable of Annihilation, have returned to the People at large for their exercise; the State remaining in the mean time exposed to all the dangers of invasion from without, and convulsions within.
I understand the sentence says that the then King of England dissolved the Congress and refused to approve newly elected ones. But I am not quite sure about the following sentence:
whereby the Legislative powers, incapable of Annihilation, have returned to the People at large for their exercise;
Does it say that Legislative power cannot be annihilated at all? So if the Legislative power is prohibited in the State [Congress], then it will return to the People in another form maybe much less efficient so then the State will be exposed to the dangers from without and within. And at large means "as a whole" or "in general".
Did I understand it correct?
