I am having a hard time figuring out specifically what bolded part means
This is from Jackson's concurrence in Youngstown (steel seizure case)
I get that it is a gray area, but not sure how to use on exam. What are imperative of events & contemp. imponderables & how does this function is practice? Is this just fuzzy language for saying it depends on the circumstances/determine on case by case basis?

JCat. 2:
When the President acts in absence of either a congressional grant or denial of authority, he can only rely upon his own independent powers, but there is a zone of twilight in which he and Congress may have concurrent authority, or in which its distribution is uncertain. Therefore, congressional inertia, indifference or quiescence may sometimes, at least, as a practical matter, enable, if not invite, measures on independent presidential responsibility. In this area, any actual test of power is likely to depend on the imperatives of events and contemporary imponderables, rather than on abstract theories of law

Thanks!

If I recall my Con Law right, it basically means "it depends on all the other shit happening at the same time in conjunction with whatever action was taken".

Think totality of the circumstances.

Considerations such as: Temporary? Emergency? Transparency? Accountability?

Just want to +1 this as well. Jackson was an exec branch atty before being a SCOTUS justice. He focused closely on practical relationships between the branches and the authority of a given branch depending upon the particular circumstances presented by the case.
