idence. In urging the Supreme Court to reject the appeal, the North Carolina attorney general's office said that while Mr. McCarver demonstrated "borderline" intellectual functioning, he was not retarded and that the question was not properly part of his appeal. Before accepting the case today, the Supreme Court had turned down two earlier appeals from Mr. McCarver, one in 1996, after the North Carolina Supreme Court affirmed the conviction and sentence, and another last Jan. 8. In the latter appeal, Mr. McCarver had sought review of a denial of a writ of habeas corpus by the United States Court of Appeals for the Fourth Circuit, in Richmond, Va.

The appeal that the justices allowed today is from the North Carolina Supreme Court's refusal on Feb. 27 to consider Mr. McCarver's constitutional challenge to his execution.February 21, 2001 National F.B.I.
