“The chief justice is presiding over the end of the rule of law in America,” Luttig told the Guardian.

In Luttig’s view, the court under Roberts is “acquiescing in and accommodating the president’s lawlessness. And it is doing so without briefing, without argument, without deliberation – and without even a single word of explanation of its decisions.”

For Luttig, this is more than just the 6-3 supermajority of the court expressing its conservatism. This is a fundamental distortion of the American legal system.

“The supreme court was never intended to function like this. Never before has it entertained such challenges from the president, and never before has it decided them so flippantly.”

“I have had four decades of knowing and respecting him,” Luttig said.

Having had a ringside seat for so many years, Luttig has no doubts about how the chief justice is conducting himself in the current fraught moment.

“John Roberts knows exactly what he is doing,” the judge said, “and he knows exactly the message he is sending to America.”

“The supreme court has pulled the rug out from under the lower federal courts, and it has done so deliberately and knowingly,” Luttig said. “The chief justice has no higher obligation than to protect the federal judiciary from attacks by this president, and in my view he has utterly failed.”
