In the case of Burdick v. United States,Marshall's doctrine was put to a test that seems to have overtaxed it, perhapsfatally. Burdick, having declined to testify before a federal grand jury on theground that his testimony would tend to incriminate him was proffered byPresident Wilson "a full and unconditional pardon for all offenses againstthe United States," which he might have committed or participated inconnection with the matter he had been questioned about. Burdick, nevertheless,refused to accept the pardon and persisted in his contumacy with the unanimoussupport of the Supreme Court. "The grace of a pardon," remarkedJustice McKenna sententiously, "may be only a pretense ... involvingconsequences of even greater disgrace than those from which it purports torelieve. Circumstances may be made to bring innocence under the penalties of thelaw. If so brought, escape by confession of guilt implied in the acceptance of apardon may be rejected." Nor did the Court give any attention to thefact that the President had accompanied his proffer to Burdick with aproclamation, although a similar procedure had been held to bring PresidentJohnson's amnesties to the Court's notice. In 1927, however, in sustaining theright of the President to commute a sentence of death to one of lifeimprisonment, against the will of the prisoner, the Court abandoned this view."A pardon in our days," it said, "is not a private act of gracefrom an individual happening to possess power. It is a part of theconstitutional scheme. When granted it is the determination of the ultimateauthority that the public welfare will be better served by inflicting less thanwhat the judgment fixed." Whether these words sound the death knell of theacceptance doctrine is perhaps doubtful. They seem clearly to indicate that bysubstituting a commutation order for a deed of pardon, a President can alwayshave his way in such matters, provided that substituted penalty is authorised bylaw and does not in common understanding exceed the original penalty.
