The leaked draft opinion that would overturn the Supreme Court’s 1973 Roe v. Wade decision remains a mystery in some respects. But two things are certain. First, the leak has damaged the court’s credibility. Chief Justice John Roberts is right to initiate a full investigation by the marshal of the court. The Supreme Court’s credibility stands to gain substantially if the culprit is identified and disciplined for his or her deeply unprofessional conduct.

Second, Roe, which established a constitutional right to abortion, justifiably appears to be on life support.
