Justice Jackson outlined the three-part model of presidential power in his dissenting opinion in the case of Youngstown Sheet & Tube Co. v. Sawyer, commonly known as the Steel Seizure Case, in 1952. This case involved President Harry Truman's attempt to seize and operate steel mills during the Korean War.

4. Note that the three parts of Jackson's model are often referred to as the "trialogue framework." These three parts are:
a. When the President acts with express or implied authority from Congress, his power is at its highest level, and he is likely to be within the bounds of the Constitution.
b. When the President acts in the absence of congressional authority or against the expressed will of Congress, his power is at its lowest ebb, and his actions are likely to be invalid unless justified by inherent presidential powers.
c. In situations where Congress has neither granted nor prohibited authority, there is a "zone of twilight" in which the President's power is uncertain, and its constitutionality must be analyzed on a case-by-case basis, balancing the needs of the President with the potential encroachment on Congress's powers.

By following these steps, you should be able to find detailed information about the Steel Seizure Case and Justice Jackson's three-part model of presidential power.
