The Court's Opinion is here: https://assets.documentcloud.org/documents/4754543/Memorandum-Opinion.pdf
Concord had two main arguments:
(1) Mueller is a "principal officer" and thus senate confirmation is required, because he has virtually unfettered authority.
(2) Even if he's an "inferior officer," the appointment is only valid if there's a statue authorizing it, and there's no such statute.
The court disagreed with #1 because Rosenstein could fire Mueller.
As to #2, the Court seemed sympathetic to Concord's argument that the statutes cited by the SC do not authorize the appointment. But she is bound by In re Sealed Case (D.C. Cir.) and US v. Nixon, which held that predecessor statutes sufficed to "accommodate the delegation at issue."
