[610]*610OPINION OF THE COURT
ROBERTS, Justice.
We are asked in these appeals to review1 appellants’ summary convictions for contempt of court.
I
Appellants were arrested on charges arising from their participation in a protest demonstration held on October 25, 1974, in Philadelphia. Trial on these charges began on January 15, 1975. At the opening of trial, the court granted appellants’ motion that they be permitted to represent themselves, but appointed a public defender to act as their legal adviser. Appellants, alleging that the judge was prejudiced by pretrial publicity and by a statement of the assistant district attorney that two appellants were charged in another case, moved for the judge to disqualify himself. This motion was denied. After some preliminary discussions, appellant Africa Africa was called upon to enter her plea. The following occurred:
“THE COURT CRYER: Africa Africa, on Bill number 2794,
October Term, 1974, charging you with disorderly conduct, failing to disperse at official order and criminal conspiracy, how do you plead ?
AFRICA AFRICA: You ask me to make a judgment? Are you asking me to make a judgment now?
THE COURT: You will enter a not guilty plea on behalf of the defendant.
[611]*611AFRICA AFRICA: If you are saying I’m not guilty, you are saying I’m innocent, right ?
THE COURT: You may go on.
AFRICA AFRICA: Are you saying I’m innocent?
THE COURT: No, madam.
AFRICA AFRICA: You said I’m not guilty.
THE COURT: That is why we are here today, madam.
AFRICA AFRICA: To do what? To try me, to find out if I’m guilty or innocent?
THE COURT: If you persist in your conversation, I assure you I will take steps.
AFRICA AFRICA: What I’d like to say — I’d like to say one thing to you. I know your reputation. I know you are supposed to be a nasty judge, but I want to know, do you get this reputation because you know what the law is or do you have this reputation because you can give out contempt charges? Because if that’s the case, anybody can hold for contempt, a bum on the street can do that.”
Appellants then asked that they be permitted to stand mute, which the judge allowed.
Appellants apparently had three theories of defense. They attempted to show: first, that they had been arrested primarily because they had been using profanity over a loudspeaker system at the demonstration; second, that their arrests were based upon the individual judgment of the arresting officers that they were using profane language; and third, that they were victims of selective enforcement of the law by the police department. Because they were unable to articulate either what the defense theories were, or their legal relevance to the charges, their questioning of witnesses was punctuated with “Objection. Objection sustained.” Further, as a result of their inexperience in a court of law, and possibly in an effort to use the court as a platform for [612]*612their views, their “cross-examination” often became either argument or their own direct testimony. This is illustrated by the cross-examination of the Commonwealth’s first witness by appellant Theodore Williamson:
“CROSS-EXAMINATION BY THEODORE WILLIAMSON—
Q. Because I am saying in my reference, bomb, science is profane. War is profane. I don’t know what you are talking about.
MR. BUTLER: Objection, that is not a question.
THE COURT: Objection sustained. These are argumentative points.
Q. Officer Patton, do you say a bomb was profane? MR. BUTLER: Objection.
THE COURT: Objection sustained.
Q. Officer Patton, do you say war is profane ?
MR. BUTLER: Objection.
THE COURT: Sustained.
Q. Do you say rape as [sic] profane ?
MR. BUTLER: Objection.
THE COURT: Sustained.
Q. Do you see either handcuffing and arresting and jailing innocent people is profane?
MR. BUTLER: Objection.
THE COURT: That too is sustained.”
Through several rounds of questioning which followed the pattern above, it is apparent that appellants were becoming increasingly restive. Then the following occurred :
“ [Appellant] CONRAD HAMPTON: I would make a motion to the Court. Have it be done on the record.
THE COURT: What is it?
CONRAD HAMPTON: I want to point out the Move Organization have been tried with injustices, so called [613]*613breaking the law. This is supposed to be a Court room of justice, a City Hall of justice. Who is going to speak of all the injustices that was poured down on the Move Organization because masochistic sheriffs and police officers beat me, when I was punched, when I was kicked and drug from the Court room, slammed into the elevator, slammed my face against concrete walls. When are these maniacs, these criminals going to be on trial?
THE COURT: Mr. Hampton—
CONRAD HAMPTON: How much longer do you intend to let these criminals go uncharged ?
THE COURT: Mr. Hampton, do you have anything further to say ?
CONRAD HAMPTON: When I say what I am saying
THE COURT: You have made your point. You may return to your seat. If you do not return to your seat, you will be bound and gagged.
CONRAD HAMPTON: Bound and gagged?
THE COURT: Yes.
CONRAD HAMPTON: What do you mean bound and gagged ? I have a right to freedom of speech.
THE COURT: He is ordered bound and gagged. I have made an order. He is to be bound and gagged. Anybody else that makes one move is going to be bound and gagged.
[Appellant] DONALD GROSSMAN: Bound and gag all of us right now.
THE COURT: Very well, gentlemen.
[Appellant] GERALD FORD: Just bound and gag me.
DONALD GROSSMAN: If one is bound and gagged, we will all be bound and gagged. If one of our organization is bound and gagged. This is the position of [614]*614the Move Organization. We will not be separated. We will always be united. If you bound and gag one member of Move Organization, you must bound and gag all members of Move Organization. This is our position. We will not compromise.
THE COURT: You may return to your seats. Everyone is to be bound and gagged.
GERALD FORD: This is a disruptive tactic. This is something you have implemented. You afforded an opportunity to make a statement, then you cut him off. Now you are attempting to cut off the principle of freedom of speech in a Court of law. That is supposed to be justice, the same type of disruptive tactic that the law enforcement officers took, to. get us bound when we walked in under your authority, and you will be held accountable for it.
THE COURT: Is there any reason why my order is not being complied with ?
AFRICA AFRICA: Move said nothing, but because of the Monday, January 13th incident, they put in security guards. They should be removed from the Court room. They have been intimidating the Move Organization.
(At this point there was a general disruption in the Court room and the Judge left the Bench.) ”
Following the noon recess, and with the mediation of a Philadelphia city councilman, appellants were permitted to return to the courtroom without restraints, on their promise that they would conduct themselves in an orderly manner. Shortly after the afternoon proceedings, began, appellants asked the court to grant a mistrial, claiming that the court had demonstrated its prejudice against them during the morning session. They stated that if this motion were denied, they would stand mute for the “continuance of the trial.” The motion was denied. The rest of the Commonwealth’s witnesses were [615]*615examined on direct and cross without incident. A demurrer to the Commonwealth’s evidence was overruled, and appellants began to present their defense.
Inspector Fencil of the Civil Disobedience Unit of the Philadelphia Police was the first major defense witness. During the direct examination of Inspector Fencil, appellants in their questioning pursued their selective enforcement theory, and their exploration of what the officer considered to be profane. During direct examination of Inspector Fencil, a second disruption occurred:
“BY CONRAD HAMPTON:
Q. Inspector Fencil, were you there at the date in question when Move people were arrested ?
A. Yes, I was.
Q. Were you in charge of that demonstration at that time?
A. I was in charge of the Civil Affairs Unit at the time.
Q. You were in charge ?
A. That’s correct.
Q. And you are telling me that you were in charge and you did not give orders to have people arrested? A. I gave warnings.
Q. I am talking about arrested, to have Move people arrested?
A. No.
Q. You did not. Now Inspector Fencil, you say that the Move Organization used words like mother fucker, bastard and as now I am saying, do you see these words as profane?
MR. BUTLER: Objection.
THE COURT: Sustained.
BY CONRAD HAMPTON:
Q. I am saying, since you feel these words are profane, why would you take them home to your wife and [616]*616play them on tapes to your wife unless your wife was a mother fucker like you ?
MR. BUTLER: Objection.
THE COURT: You will gag this defendant.
DONALD GROSSMAN: All defendants will be gagged then.
THE COURT: All the defendants will be gagged.
AFRICA AFRICA: I’d like to make a motion to you. I want you to understand that your laws state that a person has freedom of speech. Anytime you try to stifle that so called freedom of speech, you are not talking about the law. You are talking about outlaw which is what the fuckin shit you got today. Don’t your constitution say you got freedom of speech? When you try to stifle that freedom of speech, ain’t you going against the law? Ain’t you a fuckin outlaw?
‡‡‡‡‡‡‡*
(At this point the defendants were taken in the back to be gagged and there was a general disorder in the Court room, which was unreportable.)”
Following this second disruption, court was recessed until the next morning. At the opening of the session on January 16, 1975, the court on its own motion declared a mistrial and summarily found each of appellants guilty of contempt of court and sentenced them to terms of imprisonment. Appellants Hampton and Africa were found to have hurled abusive language at the court, appellant Grossman lay on the floor shouting to spectators, demanding to be bound and gagged, the remaining appellants left their seats to join in Grossman’s demand that all MOVE members be bound and gagged, using obscenities to express their request. Africa, Hampton and Grossman were sentenced to ninety days in prison, the remaining appellants were sentenced to thirty days.2
[617]*617It is unclear whether an appeal was taken to the Court of Common Pleas of Philadelphia. The brief for the Commonwealth asserts that such an appeal was taken and denied for want of jurisdiction on January 23, 1975. There is, however, no entry of this appeal in the record. An earlier contempt case arising from another trial in the Municipal Court involving these same appellants was appealed to the Court of Common Pleas of Philadelphia and that appeal was denied for want of jurisdiction on December 12, 1974.3 This Court, per Mr. Justice Nix, assumed jurisdiction of the appeal from the earlier contempt case by a grant of supersedeas and bail on December 13, 1974. On February 19, 1975, this Court assumed jurisdiction over these cases by a per curiam [618]*618grant of supersedeas and bail.4 We vacate the judgments of sentence, discharge three appellants and remand four of the causes to the Municipal Court of Philadelphia for a new trial on the contempt charges.5
II
The purpose of a criminal trial is to determine the guilt or innocence of the accused.6 Any conduct not directed to this end is improper and should be controlled by the court.7 “[I]t is ultimately the authority and responsibility of the trial judge which must be exercised to maintain the atmosphere appropriate for a fair, rational and civilized determination of the issues . . . 8
Special problems seem to be presented when people who believe that the “system” ought to be on trial are themselves on trial for violations of the law. Such persons, apparently having no faith in the constitutional process and procedures of courts of law, feel no obligation to cooperate, even passively, with those courts. The law is not concerned with their lack of faith in the judicial process. Our system of government is founded on [619]*619the precept that everyone has the right to believe what he will, whether that belief is held by millions or by one.
The weight of the law comes to bear on such persons only when they move deliberately to disrupt the judicial process. When such disruptions occur, courts properly act to defend themselves, their process and, ultimately, the system by which the people of our nation have chosen to assure that each man may have his conduct justly measured against the norms of conduct prescribed in the criminal law.9 Disruptions in a court of law, of whatever kind, threaten the ability of the court to act justly. As a consequence, they cannot be tolerated.
Here we are confronted with a case in which people who had demonstrated to express their dissatisfaction with certain aspects of the “system” were on trial for charges arising out of that demonstration. They sought and received permission to represent themselves.10 Then, given this license, they proceeded to defend themselves. They quickly came to realize that their trial strategy was vindicating neither their actions nor their views.11 Frustrated and disappointed, they began to play to the audience. The court was required, by [620]*620its duty to defend the judicial process, to control the defendants and to keep the trial focused on the narrow issue of guilt or innocence.
In this case the court chose to control the defendants by binding and gagging them. Though this was an alternative which was within the court’s discretion to use,12 we must express our disapproval13 of its use here. In a trial which is already charged with emotion, the sight of manacled and gagged defendants can do nothing to reduce tensions. “It offends not only judicial dignity and decorum, but also that respect for the indi[621]*621vidual which is the lifeblood of the law.” 14 A gagged defendant cannot communicate15 and cannot conduct a defense, and thus normally has no place in a court of law.
Courts have, in recent years, been confronted with many disruptive defendants. The legal community and the courts have developed techniques by which such defendants may be tried as fairly and in as orderly a manner as possible.16
Potentially disruptive defendants, like all defendants, have the right to represent themselves if counsel is validly waived.17 Whenever a defendant seeks to represent himself, and particularly when he may be disruptive, standby counsel should be appointed.18 The court should explain to the defendant the standards of [622]*622conduct he will be expected to observe.19 If the defendant misbehaves, he should be warned 20 that he will be removed from the court,21 his right to represent himself will be considered waived,22 and the trial will continue in his absence with standby counsel conducting the defense.23 If the defendant again misbehaves, these measures should be taken. The defendant must be made to realize that his disruptive tactics will result only in his exclusion from the courtroom. His case will be tried according to law, in an attempt to do justice, whether he cooperates or not.
In this case the conduct of the defendants forced the declaration of a mistrial, despite the sanction imposed by the court. Such a result is precisely the opposite of that sought to be obtained by the imposition of sanctions. It is a defeat for the judicial system, because its orderly process has been frustrated.
[623]*623III
Following the declaration of a mistrial, the trial judge summarily24 found each of the defendants guilty of contempt of court and sentenced them to terms of imprisonment. The contumacious acts consisted in each case of profane language directed at the court, coupled with various disruptive acts. The court was personally attacked, and was subjected to abusive language and epithets. During the course of a trial, a summary proceeding to protect the orderly administration of justice is perfectly proper, even when the court is personally attacked.25 The court must be able to control those appearing before it, and must be able to use its power summarily to avoid interference with the principal matter before the court.26
Once the trial is terminated for any reason, however, different considerations come to bear.27 No legitimate [624]*624interest is served by permitting the court victimized by the attack summarily to convict and punish the defendants for contempt of court. There is no trial to be interrupted, there is no need to forestall future contumacious behavior, there is no reason to deny the defendants “the ordinary rudiments of due process.” A summary conviction for contempt of court, after termination of a trial in which the court has been personally attacked, lends itself to charges that the court is exacting personal vengeance.28 Whether this is the case need not concern us, for even the appearance of such motives on the part of a trial court is strictly to be avoided.29 For this reason, four appellants 30 must be tried before a court that has not been directly subjected to their abuse.31
[625]*625IV
Three appellants 32 correctly assert that the record does not support their contempt convictions. Review of the trial transcript reveals that there is no evidence of the contemptuous conduct cited by the trial court as the basis for the contempt convictions of three of the seven appellants. The trial court, however, in its opinion, written three months after the trial, stated that during one of the outbursts in the courtroom which the court reporter was unable to report, these three appellants jumped up, and in abusive language, demanded that the court bind and gag all of them.
We have no doubt that the court has accurately recited what transpired during this outburst in its presence. In Commonwealth v. Young, 456 Pa. 102, 317 A.2d 258 (1974), however, we held that a trial court’s attempt to “correct” the official transcript of the proceedings during an appellant’s trial was impermissible. “[T]his Court may not accept as correctly reflecting what occurred at trial, anything other than the original record or a record corrected in accordance with section 1199.” Commonwealth v. Young, id. at 113-14, 317 A.2d at 264. See also Commonwealth v. McDonald, 459 Pa. 17, 326 A. 2d 324 (1974); Commonwealth v. Lofton, 389 Pa. 273, 133 A.2d 203 (1957).
If a trial court, for any reason does not wish to comply with section 1199, the only other procedure which may be followed, in cases such as this, was used by the trial court in Commonwealth v. Patterson, 452 Pa. 457, 460-61, 308 A.2d 90, 92 (1973). In that case the trial judge, following a violent disruption by several defendants in his courtroom, waited until order had been restored and then dictated to the court reporter a description of what had transpired during the outburst. This report was [626]*626then read to each of the defendants before the court imposed sentence for contempt of court. Thus the record was made in open court, it was part of the official records of the proceedings, and each defendant was able to refute, if necessary, the court’s version of events.33
Because we may consider only the official record of the proceedings, it is clear, as previously indicated, that there is insufficient evidence to sustain the contempt of court convictions of three of the appellants. Once that is established, this case is no different than any other sufficiency of the evidence challenge. Because there is insufficient evidence to support a conviction, the appellants whose convictions are not supported by the evidence must be discharged. See Commonwealth v. Stanley, 453 Pa. 467, 475, 309 A.2d 408, 413 (1973); Commonwealth v. Wright, 449 Pa. 358, 362, 296 A.2d 746, 748 (1972); Commonwealth v. Bailey, 448 Pa. 224, 230, 292 A.2d 345, 347 (1972); Commonwealth v. Walker, 428 Pa. 244, 250, 236 A.2d 765, 768 (1968); Commonwealth v. Bausewine, 354 Pa. 35, 42, 46 A.2d 491, 494 (1946).
The remaining four appellants contend that (1) they were deprived of their right to make statements or present testimony on their own behalf at a hearing on the contempt charges, (2) their acts of contempt were caused by their defective waiver of counsel at the trial which gave rise to the contempt charges, and (3) the judge’s recitations of the alleged contumacious conduct were too vague to permit informed appellate review.
The first contention is remedied by the grant of a new trial on the contempt charges. The second contention may be presented at that trial. The third is without merit. This Court had no difficulty understanding which acts of appellants were the basis for the trial court’s findings of contempt.
[627]*627Judgments of sentence of appellants Merle C. Austin, Laverne Sims and Theodore Williamson reversed, and these appellants ordered discharged. Judgments of sentence of Africa Africa, Conrad Hampton, Gerald Ford and Donald Grossman vacated and causes remanded for a new trial of the contempt charges in conformity with this opinion.
MANDERINO, J., concurs in the result.
JONES, C. J., filed a dissenting opinion.
NIX, J., filed a dissenting opinion in which POMEROY, J., joins.
