How is the power of executive branch of government limited?

The executive branch of government is responsible for enforcing the laws of the United States

The president of the United States does not have the power to pass laws but can pass something called an executive order. An executive order has the full force of law with some exceptions.

Executive orders can be passed to manage other executive branch agencies or because permission has been granted by the legislative branch, or Congress. An example might be when the Congress deems the United States to be in a state of emergency. Even then, these permissions only last for a certain length of time. Executive orders can also be struck down in federal court if the judicial branch thinks the order is against the constitution.
