The U.S. Supreme Court’s ruling Friday in the challenge to the Texas anti-abortion law was perhaps the starkest evidence yet of a gap between the conservatism of Chief Justice John Roberts Jr. and the three newest, Trump-appointed justices.

The gap wasn’t so much in their differences over the important procedural aspects of the challenge to the law brought by a Texas abortion clinic and others. It was in the complete lack of comment by the decision’s main author, Justice Neil Gorsuch, or his colleagues on the right, about what Roberts saw as what was really at stake in the case before them: the role of the Supreme Court in the U.S. Constitution’s design.
