Actually, it was Gov. Rudy Perpich of Minnesota who refused, and was batted down (unanimously, btw) by the Supreme Court. Once the President nationalizes a state’s NG (or any part of it), the Governor of that state becomes as powerful in guiding the nationalized units as some beggar in the streets.
The Perpich decision was important for another reason besides asserting the absolute primacy of the President over a state government in these circumstances: by showing that the NG could be federalized with the stroke of a Presidential pen, it gave lie to the assertion by gun control/gun confiscation advocates that the National Guard of each state is that state’s militia - it is manifestly NOT, it is a federal unit that is based in, and peopled by citizens of, that particular state...but that is all.

You are correct. However, Gov Dukakis had filed a similar claim and was also rejected for the same reasons.
