At this point I have to wonder if judicial intervention will have any effect; a court ruling only matters if the administration decides to obey it. There's a lot of frozen funds which legally cannot be frozen due to them either not being subject to executive control (e.g. Medicaid funds[0]) or because there are contractual obligations for dispersal (e.g. many infrastructure projects), so it seems unlikely that a little thing like the law is going to make a difference here.
As someone in higher ed, this all worries me greatly. My position may not be federally funded, but if layoffs occur to balance the budget, I'm relatively low on the seniority ladder.
