Chief Justice John Roberts Jr.’s majority opinion in the census case has drawn sharp criticism from several veteran U.S. Supreme Court advocates, including a prominent conservative lawyer who predicted the “one-off” ruling against the Trump administration won’t be taken seriously.

Jones Day partner Michael Carvin, in his typically blunt style, called the decision “one of the more illogical and internally contradictory decisions that’s come out of the Supreme Court in recent years.” The 5-4 ruling on June 27 blocked the Trump administration’s effort to place a citizenship question on the 2020 decennial survey.
