Having judicial powers gives the President the authority to check the actions of the federal courts.

Explanation:

For any federal court decisions that are found not to be reasonable by the President, he has the power to question the decision and ask for the grounds that the decision is based on.

This power allows him to exercise his responsibility of making sure that the federal courts aren't exhibiting absurd behaviour that is motivated by personal beliefs and choices.
