Vacated and remanded by published opinion. Judge WILKENS wrote the opinion, in which Senior Judge BUTZNER and Senior Judge MICHAEL joined.
OPINION
Whitt Neal appeals an order of the district court finding him guilty of criminal contempt for failing to obey a subpoena. See 18 U.S.C.A. § 401(3) (West 1966). Because the district court committed plain error in failing to refer the matter to the United States Attorney or some other appropriate prosecutor, we vacate Neal’s conviction and remand for further proceedings consistent with this opinion.
I.
Neal, an officer with the Charlotte-Meek-lenburg Police Department, was responsible for coordinating law enforcement efforts regarding the activities of various abortion-protest groups. On January 25, 1996, Neal was served with a subpoena directing him to appear in federal district court on the morning of February 2, 1996 to testify as a witness in a civil lawsuit involving some of the protestors. Neal failed to appear in court pursuant to the subpoena. As a result, the district court issued an order requiring Neal *996 to appear and show cause why he should not be held in contempt of court.
The district judge conducted the resulting hearing without the aid of a prosecutor, deciding himself which witnesses would testify against Neal. The court called four witnesses to the stand and conducted the direct examination of them. It is apparent that the court learned the substance of the testimony of these witnesses prior to the hearing through extrajudicial means. The principal witness against Neal was Christine Stole, the process server who served him with the subpoena. Stole testified on direct examination that when she gave Neal the subpoena he commented, “I’m going to throw this in the trash can.” J.A. 19. During cross-examination, Stole conceded that she could not be sure he was referring to the subpoena. The court also called as witnesses two Deputy United States Marshals and Neal’s supervisor, all of whom had conversations with Neal relating to his failure to appear.
Neal, who was represented and examined by counsel, testified that he did not intentionally disobey the subpoena. He claimed that he inadvertently overslept, having worked the night shift on the evening prior to February 2, 1996. Consequently, he argued, he lacked the requisite criminal intent for a contempt conviction. The district court conducted a brief cross-examination, during which Neal admitted that he received the subpoena and that he was aware thát he was required to appear. Discounting Neal’s explanation for not appearing, the court concluded that he wilfully disobeyed the subpoena. Neal was sentenced to a two and. one-half day term of imprisonment.
II.
Neal contends that the district court erred in assuming the inconsistent roles of prosecutor and judge during the hearing. Because Neal failed to raise this objection below, we will reverse only if the district court committed plain error in failing to refer the matter to the United States Attorney or otherwise appoint a prosecutor.
See
Fed.R.Crim.P. 52(b);
United States v. Olano,
A.
Our first inquiry is whether the district court erred in conducting Neal’s criminal contempt hearing without the aid of a prosecutor. We conclude that it did.
It is well established that courts possess an inherent “‘power to impose silence, respect, and decorum, in their presence, and submission to their lawful mandates.’”
International Union, UMWA v. Bagwell,
The power of a court to impose sanctions for civil contempt differs in several respects from its authority to impose sanctions for criminal contempt, including the
*997
procedural safeguards that must be followed.
See Bagwell,
512 U.S. at -,
The procedures attendant to the prosecution of a criminal contempt charge depend largely upon whether the conduct constitutes direct or indirect contempt.
See Young,
Among those procedures that are fundamental to our adversary system is the use of an independent prosecutor to pursue charges against a criminal defendant. It is axiomatic that the prosecution of crimes is not a proper exercise of the judicial function.
See, e.g., In re Murchison,
Here, it is undisputed that the proceedings against Neal were criminal in nature. Further, it is clear that Neal’s conduct constituted indirect contempt since the court did not witness “all of the essential elements of the misconduct.”
In re Oliver,
B.
Having determined that the district court erred in prosecuting the contempt charge against Neal, we next turn to the question of whether the error is plain. An error, to be plain, must be “clear” or “obvious.”
Olano,
At the time of Neal’s hearing, the settled law of the Supreme Court was abundantly clear that the simultaneous assumption of the inconsistent roles of prosecutor and judge transgresses our most fundamental notions of procedural fairness.

In
In re Murchison,
the Supreme- Court held that it was error for a judge to initiate, prosecute, and adjudicate charges of indirect criminal contempt.
In re Murchison,
C.
We next address the question of whether the error affects substantial rights.
See Olano,
The separation of powers among the branches of government is a foundational principle to our system of government; the idea of lodging in one individual the power to prosecute and sit in judgment “summons forth ... the prospect of the most tyrannical licentiousness.”
Bagwell,
512 U.S. at -,
D.
Even if a district court commits an error that is plain and that affects substantial rights, the use of our authority to correct the error remains discretionary.
See Olano,
Our review of the record convinces us that it is appropriate to notice the plain error of the district court. The melding of the judicial and prosecutorial functions is a fundamental error that undercuts the dispersion of power among the branches and, as a result, casts doubt'on the integrity of the judicial process. To allow a district court to *1000 investigate the matter, call the witnesses for the prosecution, conduct the direct examination of them, and sit in judgment of the defendant undoubtedly undermines the fairness, integrity, and public reputation of judicial proceedings.
III.
For the foregoing reasons, we vacate Neal’s conviction for criminal contempt and remand for further proceedings consistent with this opinion before a different district judge. 5
VACATED AND REMANDED.
Notes
. Except for serious criminal contempts, the procedural safeguards required for criminal contempt proceedings do not apply when the conduct in question occurs in the actual presence of the court.
See Bagwell,
512 U.S. at - n. 2,
. Federal Rule of Criminal Procedure 42 preserves the historical distinction between in-court and out-of-court contempt.
See Young,
. An error is "plain” if the “error is clear both at the time of trial and at the time of appeal.”
See David,
. The First Circuit recognized in
In re Grand Jury Proceedings
that the failure to appoint an independent prosecutor may well require the judge impermissibly to fill the role himself.
In re Grand Jury Proceedings,
. Generally, there would be no impediment to the same judge handling the adversarial proceedings for indirect contempt unless an appearance of impropriety would indicate that recusal was appropriate.
