The newspaper comic strip “Calvin and Hobbes” had a fictional game called “Calvinball,” the rules of which are made up and constantly changing. The only fixed rule is that you can’t play it the same way twice.

The game appeared in a Supreme Court opinion Thursday, when Justice Ketanji Brown Jackson accused her colleagues of “Calvinball jurisprudence with a twist.”

In a solo opinion on the Trump administration’s quest to cut National Institutes of Health research grants, she wrote that in the court’s version of Calvinball, “this Administration always wins.”
