is that like when Congress passed legislation and gave Biden the power to "Waive or Modify" loans, including student loans but because Republicans were against it the SC ruled that kanguage was not specific enough for him to "Cancel" as if "cancel" is not a "modification" of the loans?
In law, language has to be precise. So, yes, the Supreme Court was correct that "waive or modify" doesn't include "cancel."
On the other hand, what District Court judges, on the Left mainly, started doing once Trump took office again, was having a single plaintiff come before them suing about something the Trump administration was doing. They'd take that lawsuit and then slap a nationwide injunction on the administration stopping that action in all cases even though they had a single plaintiff in their courtroom and their jurisdiction was limited to the district they were assigned to.
The Supreme Court smacked that down permanently removing almost all ability for district court judges to make rulings that impacted anyone or area of the country outside their district. Yes, there were some, a few by comparison, cases of Rightwing judges doing likewise against Obama or Biden. But with the return of Trump to power, it became a virtual political crisis where district judges were now running the country or so it seemed.
Now, what you are seeing is those same District Court judges handing down rulings for their district that get tossed on appeal at the Appellate or Supreme Court level. In fact, just in the last week something like a half dozen such rulings came down tossing out restrictions imposed on ICE by one District Court judge or another.
If anything, politically Leftist District court judges are shooting the judiciary in the foot by fighting Trump tooth and nail on everything. They are letting politics dictate their rulings and in the long run they're losing their power to make rulings on more and more.
