Although the New England states rejected the Kentucky and Virginia Resolutions in 1798–99, several years later, the state governments of Massachusetts, Connecticut, and Rhode Island threatened to ignore the Embargo Act of 1807 based on the authority of states to stand up to laws deemed by those states to be unconstitutional. Rhode Island justified its position on the embargo act based on the explicit language of interposition. However, none of these states actually passed a resolution nullifying the Embargo Act. Instead, they challenged it in court, appealed to Congress for its repeal, and proposed several constitutional amendments.
