Answer:
A president is most likely to use an executive order to implementing policy when Congress refuses to pass laws the president supports.
Explanation:
An executive order is a directive issued by the President that has the force of law. However, executive orders are subject to judicial review. This means that they can be overturned by the courts if they lack support by the Constitution.
Only the President can issue an executive order because of his role as head of state and Commander-in-Chief of the Armed Forces.

Basing this mostly on the Social Contract theory, the Founding Fathers used this section to justify that their rights as Englishmen and free folk had been impeded upon by the British and so they had both the philosophical and political right to break away.
