An inherent authority of federal courts to formulate procedural rules and remedies in federal criminal proceedings that extend beyond those compelled by the Constitution, statutes, or court rules. This power permits courts to impose standards ensuring the integrity of judicial processes, such as regulating grand jury presentations or excluding evidence obtained through regulatory violations. Courts may not use the power to create new standards of prosecutorial conduct before the grand jury or to override harmless-error rules.
In a federal criminal prosecution, the district court invokes its supervisory power after a prosecutor presents misleading grand-jury testimony. The court dismisses the indictment to protect judicial integrity even though no constitutional violation occurred, then considers whether the error was harmless.
Former SEC lawyer Solomon Silver supervised a case while at the agency. He later joins a firm representing a defendant in the same matter. The court disqualifies Silver personally but permits the firm to continue after screening measures are implemented and the government consents, balancing the risk of information misuse against public enforcement interests.
During a federal criminal trial the court exercises supervisory power to exclude evidence obtained in violation of internal agency regulations. The prosecutor argues the violation was harmless, but the court imposes the remedy to deter future regulatory breaches and preserve process integrity.
A federal prosecutor withholds exculpatory material from the grand jury. The district court uses its supervisory power to dismiss the indictment as a prophylactic measure, then weighs whether the error affected substantial rights under the harmless-error rule.
A federal prosecutor comments on a defendant's failure to testify during closing argument. The trial court finds the comment improper but concludes it did not affect the verdict. On appeal the court exercises supervisory power to determine whether the error requires reversal or may be disregarded under the harmless-error standard.
Ruth Elizabeth Chapman and Thomas LeRoy Teale were convicted in a California state court upon a charge that they robbed, kidnaped, and murdered a bartender. Chapman was sentenced to life imprisonment and Teale to death. At trial both petitioners chose not to testify. The prosecutor took full advantage of a provision in the California Constitution allowing comment on a defendant's failure to testify, filling his argument to the jury from beginning to end with numerous references to their silence and inferences of guilt. The trial court also charged the jury that it could draw adverse inferences from petitioners' failure to testify. The trial took place before this Court decided Griffin v. California. On appeal the California Supreme Court acknowledged that petitioners had been denied a federal constitutional right by the comments on their silence but affirmed applying the State's harmless-error provision. The Supreme Court granted certiorari limited to these questions: where there is a violation of the rule of Griffin v. California, can the error be held to be harmless, and if so, was the error harmless in this case.
View caseOn appeal from a federal conviction the court considers whether to exercise supervisory power to reverse for a non-constitutional grand-jury irregularity. The court declines, holding that the harmless-error rule prevents use of the power to reverse for errors that did not affect substantial rights.
In December 1973, the Public Service Commission ordered electric utilities in New York State to cease all advertising that promoted the use of electricity because the interconnected utility system lacked sufficient fuel stocks for the 1973-1974 winter. The order rested on the Commission's finding that the system did not have sufficient fuel stocks or sources of supply to meet customer demands. Three years later, when the fuel shortage had eased, the Commission requested comments from the public on its proposal to continue the ban on promotional advertising. Central Hudson Gas & Electric Corp. opposed the ban on First Amendment grounds. After reviewing the public comments, the Commission extended the prohibition in a Policy Statement issued on February 25, 1977. The Policy Statement divided advertising expenses into promotional and institutional categories. It permitted informational advertising designed to encourage shifts of consumption from peak demand times to periods of low electricity demand. The Commission banned promotional advertising because additional electricity would be more expensive to produce and promotional advertising would give misleading signals to the public. Central Hudson challenged the order in state court. The order was upheld through the New York Court of Appeals. The Supreme Court noted probable jurisdiction and reversed.
View caseNo. The Supreme Court has held that supervisory power may not be used to prescribe standards of prosecutorial conduct before the grand jury or to dismiss indictments for violations of court-created rules that go beyond statutes, the Federal Rules, or the Constitution.
Generally no. The Supreme Court has rejected automatic exclusion for violations of internal agency policies, emphasizing that such regulations are desirable but that rigid application of an exclusionary rule would discourage their adoption.
Federal Rule of Criminal Procedure 52(a) limits the use of supervisory power by requiring courts to disregard errors that do not affect substantial rights. Courts may not employ supervisory power to reverse convictions for non-prejudicial errors as a prophylactic measure.
Federal courts possess no general supervisory power over state courts. The supervisory power operates only within the federal judicial system and cannot be used to impose procedural requirements on state proceedings.
…these and other witnesses without having the prosecutor present. Whether today's judgment would be an acceptable exercise of supervisory power over federal courts is another question. But as a constitutional matter, the judgment in this case is erroneous and although I concur in Parts I and III of the Court's opinion I…
