The USSC decision isn't as clear as you make it sound.
The district judge "may have" exceeded its authority regarding foreign affairs.
The rest of the District Court’s order
remains in effect but r
equires clarification on remand. The
order properly requires the Government to “facilitate”
Abrego Garcia’s release from custody in El Salvador and to
ensure that his case is handled as it would have been had
he not been improperly sent to El Salvador.
The intended
scope of the term “effectuate” in the District Court’s order
is, however, unclear, and may exceed the District Court’s
authority. The District Court should clarify its directive,
with due regard for the deference owed to the Executive
Branch in the conduct of foreign affairs. For its part, the
Government should be prepared to share what it can con-
cerning the steps it has taken and the prospect of further
steps. The order heretofore entered by T HE CHIEF J USTICE
is vacated
p.s if you think Roberts and Amy Coney Barrett aren't "swing" enough, just wait until Trump gets a few more picks.
