3."interposition" and "nullification" 介入和废止
Interposition is a claimed right of a U.S.state to oppose actions of the federal government that the state deems unconstitutional. Nullification holds that the states have the right to nullify federal laws that are deemed unconstitutional and to prevent enforcement of such laws within their borders.The doctrines of interposition and nullification had been invoked by segregationists. Segregation supporters argued that the states have the power to nullify federal laws or court rulings that they believe to be unconstitutional.
“介入权”和“废止权“”是指美国各州主张其对于它认定为违宪的联邦法律享有宣告无效并予以废止的权利。但是，1958年美国联邦最高法院在 Cooper v. Aaron 案中否决了州的该项权利，并明确指出联邦法律是否违反宪法只能由联邦司法机构认定。
（ps:专业相关，所以想多了解一些。想要详细了解的，可以去Wikipedia 搜索“interposition”“nullification”）
