When this government or legislature doesn't fulfill its duty on the social contract.
Explanation:
John Locke was one of the first philosophers to talk about a minimum government. According to him, the only duty of the government was to maintain the welfare state through social policies. The Social Contract address that the people have the right to take down this government if it is not following the rules because according to the contract, the non-following of the rules causes the loss of credibility and the right to rule.
The general consensus amongst historians is that the balance between Federal and State powers was done to appease those who were afraid that too strong of a federal government would be no different than the monarchy that the colonists were overthrowing.
