Sharing a stage, Supreme Court Justices Ketanji Brown Jackson and Brett Kavanaugh sparred Monday over the many emergency orders the court has issued allowing Donald Trump to move ahead with key parts of his agenda.

The issue in emergency appeals is whether a policy that has been challenged in court should be allowed to take effect while a legal case that could last for years continues.

Jackson, a frequent dissenter from the emergency orders, said Kavanaugh and the other conservatives who repeatedly sided with Trump last year were not serving the court or the country well.

“The administration is making new policy ... and then insisting the new policy take effect immediately, before the challenge is decided. This uptick in the court’s willingness to get involved in cases on the emergency docket is a real unfortunate problem,” Jackson said to loud applause.
