Final answer:
An executive order can be stopped from going into effect through court rulings, reversals by later presidents, and potential veto overrides by Congress.
Step-by-step explanation:
Executive orders can be stopped from going into effect through various means. One way is through court rulings or changes in policy enacted by Congress. The Supreme Court, for example, can revoke an executive order if it is found to be unconstitutional. Additionally, a later president can reverse the order, and recent presidents have frequently reversed the orders of their predecessors in cases of disagreement.
Another important factor is the authority of the executive order. If the order has prior authority from Congress, it is less likely to be overturned. However, if there is no prior authority, it is more likely to be overturned by a later president.
Congress also has the power to override a presidential veto with a two-thirds majority in both the House and the Senate, which can effectively prevent an executive order from going into effect. Therefore, the President's ability to issue executive orders is limited by the checks and balances of the judicial branch, congressional action, and the possibility of a veto override by Congress.
