> I think most of the decisions of the "conservative" court have been along the lines that congress should do its job.
They have repeatedly reduced Congressional powers, including today, where they basically said Congress can't setup genuinely independent agencies (in Slaughter). Or when they kneecapped the VRA.
Some of them likely subscribe privately to https://en.wikipedia.org/wiki/Unitary_executive_theory.
> can't setup genuinely independent agencies
The US constitution lays out three AND ONLY three branches of government. The congress cannot create a fourth without an amendment. If they create an agency in the executive branch, by definition it reports to the head of the executive.
Slaughter determined that agencies congress had ceded to the executive branch had control of the executive. It doesn't stop congress from directly exercising that power instead. It just says you can't play the fuck-fuck game where you pretend to create an agency in the executive branch but actually violate the constitution by trying to create a new branch.
