"No body of men can be said to authorize a man to act as their agent, to the injury of a third person, unless they do it in so open and authentic a manner as to make themselves personally responsible for his acts. None of the voters in this country appoint their political agents in any open, authentic manner, or in any manner to make themselves responsible for their acts. Therefore these pretended agents cannot legitimately claim to be really agents. Somebody must be responsible for the acts of these pretended agents; and if they cannot show any open and authentic credentials from their principals, they cannot, in law or reason, be said to have any principals. The maxim applies here, that what does not appear, does not exist. If they can show no principals, they have none."
