Chief Justice John Roberts made clear that he saw the student debt forgiveness as an important opportunity for the court to further flesh out its "Major Questions Doctrine."
"We take very seriously the idea of separation of powers and that power should be divided to prevent its abuse," Roberts told US Solicitor General Elizabeth Prelogar. He said that the case reminded him of a decision from the Trump administration where the court blocked Trump's efforts to end the "Dreamers" program for young undocumented immigrants brought to the United States as minors.
"I just wonder, given the posture of the case and given our historic concern about the separation of powers, you would recognize at least that this is a case that presents extraordinarily serious important issues about the role of Congress and about the role that we should exercise in scrutinizing that, significant enough that the Major Questions Doctrine ought to be considered implicated?" Roberts said.
Remember: Under the “Major Questions Doctrine," if an agency acts in a way that could have major political or economic implications, it must have the authority of Congress. The states are saying here that essentially, the college debt relief plan is too big for the Biden administration to use the authority in its citing.
