The source of the powers of congress is to be sought solely in the acquiescence of the people, without which every congressional resolution, with or without the benediction of popular conventions or state legislatures, would have been a mere brutum fulmen; and, as the congress unquestionably exercised national powers, operating over the whole country, the conclusion is inevitable that the will of the whole people is the source of the national government in the United States, even from its first imperfect appearance in the second continental congress...

Consent thus obtained undermines the legitimacy of government. Bernays claimed that "the basic principle involved is simple but important: If the opinions of the public are to
