Supreme Court Justice Ketanji Brown Jackson took aim at her colleagues Monday with a blistering rebuke of what she labeled as their “unusual” move, one that she claimed had been done no more than three times in the last quarter century, The Washington Post reported Tuesday.

Jackson was referring to the Supreme Court’s landmark ruling in late April when it voted to effectively gut a provision of the Voting Rights Act designed to prohibit racially discriminatory voting policies. The court was deciding on a matter related to Louisiana's congressional district map, with Republicans having challenged a lower court’s order requiring state lawmakers to create a second majority-Black district.

Supreme Court justices Ketanji Brown Jackson and Brett Kavanaugh sparred publicly on Monday over how the court has repeatedly stepped in to aid policies pushed by President Donald Trump.

The rare exchange occurred during a joint appearance at a federal courthouse event in Washington, D.C., where the two justices discussed the court’s growing use of emergency rulings – often referred to as the “shadow docket,” according to NBC News.

Liberal Supreme Court Justice Ketanji Brown Jackson warned last summer that her conservative colleagues on the bench were doing irreparable harm to the court’s image as they increasingly sided with the rich and powerful, and a new study published Monday appeared to validate those fears.

Published by the National Bureau of Economic Research, the study found that since the 1950s, conservative Supreme Court justices increasingly issued rulings that favored the wealthy when compared to their liberal counterparts.

One of the sharpest legal minds ever to stand before the Supreme Court decided to have a little fun with the justices Monday — and got a pointed reminder from the bench that daring the nation's top judges is a risky game, Courthouse News Service reported.

Lisa Blatt has argued more cases before the Supreme Court than any other woman in American legal history. On Monday she was back at the podium, this time defending a Maryland hospital system in a dry but consequential fight over the boundaries of federal court power.

Election law experts and liberal Justice Ketanji Brown Jackson argue the Supreme Court's conservative majority is selectively applying the Purcell principle to aid Republican gerrymandering efforts.

The Purcell principle was first articulated in the 2006 case Purcell vs. González, and it limits election changes close to voting.

The Supreme Court issued a 6-3 decision Monday allowing Louisiana to redraw its congressional map and eliminate a majority-Black district, exposing a rare public dispute between conservative Justice Samuel Alito and liberal Justice Ketanji Brown Jackson.

According to CNN, Jackson, the lone dissenter, accused the majority of taking steps to "influence its implementation" of last week's Voting Rights Act ruling and suggested the court should have recused itself to avoid appearing partisan. She criticized the decision as "tantamount to an approval of Louisiana's rush to pause the ongoing election" to pass a new map.
