The defendant, Louis DeUaCamera, was convicted in a jury trial of two counts of indecent assault and one count of conspiracy to commit the crimes of rape, indecent assault, sodomy, robbery with violence and aggravated assault. The defendant’s motion to set aside the verdict- was denied by the trial court. From the judgment rendered thereon, he has appealed, assigning error in certain rulings on evidence, in the court’s refusal to grant a motion for a mistrial and in the court’s refusal to allow him to examine exhibits for identification to aid him in his appeal. This was a companion case to State v. Clemente, ante, 501, and State v. Esposito, ante, 550, both decided this day.
In the late evening of April 12 and the early morning hours of April 13, 1969, two young females and one young male, the complaining witnesses, were subjected to a series of sexual assaults by a group of males belonging to a motorcycle club known as the Slumlords. Reference is made to State v. Clemente, supra, for more detailed facts. Among those who allegedly forced both of the female complaining witnesses to commit indecent assaults upon him and who conspired with others that rape, aggravated assaults and indecent assaults be committed was the defendant, Louis DeUaCamera. During the trial both female complaining witnesses identified the defendant as one of the persons who forced them *559 to commit an indecent assault on Mm and the male complaining witness identified the defendant as having been in the station wagon that evening.
The defendant has assigned as error two rulings made by the court denying discovery motions under § 54-86b of the General Statutes.
On direct examination the two female complaining witnesses described the series of assaults which they were forced to commit on the evening of April 12 and the early morning of April 13, 1969. When the defendant entered the station wagon, one of the girls noticed he had a marred complexion and fairly long, straight hair. The other gave a verbal description of the defendant to the police from what she remembered from the night of April 12,1969. Each of the two female complaining witnesses had furnished the police with written statements relating to their direct testimony. One gave five statements and the other gave six statements. The defendant requested the statements of the first female complaining witness from the state’s attorney as of right under § 54-86b. The court had previously made it abundantly clear that it would not recognize the validity of the statute. It had also previously stated to all counsel that it would examine any statement to determine if there were inconsistencies under the rule of such cases as
Hurley
v.
Connecticut,
In addition to the issues raised in the case of
State
v.
Clemente,
supra, as to § 54-86b, this defendant claims that the validity of the statute has been implicitly recognized in at least two cases. In his brief, the defendant refers to
State
v.
Menillo,
While the defendant has not phrased his argument in terms of acquiescence, his claim cannot be dismissed without acknowledging this principle. It is true that rules of court derive from custom and convention as well as from the formally promulgated sections of the Practice Book. See
Adams
v.
Rubinow,
The court was not in error in refusing to be bound by § 54-86b and in holding that if counsel requested prior statements of witnesses on the stand, they were to follow recognized procedures. State v. Clemente, supra.
The defendant also claims the court erred in a second set of rulings on § 54-86b. After the testimony of the first female complaining witness that she had made statements to the police, the court denied the defendant’s motion for production of the statements under § 54-86b. The defendant then moved that the testimony of the witness be stricken pursuant to § 54-86b. The court denied the motion and an exception was taken. This process repeated itself after the testimony of the other female complaining witness. The second portion of the statute, § 54-86b (b),
1
provides that where a court orders the production of statements, and the prosecution fails to comply with the order, the testimony of the witness whose statements are not produced shall
*563
be stricken. The defendant’s claim fails for two reasons: First, since the court did not order production of the statements, the defendant lacked the proper foundation for proceeding under part (b) of the statute. Second, “[wjhere two or more parts of a statute are challenged, the test is whether they are so mutually connected and dependent as to indicate a legislative intent that they should stand or fall together.”
Amsel
v.
Brooks,
While the appeal in this case was pending, the defendant filed a motion to the trial court for permission to examine the written statements of witnesses which had been made exhibits for identification whenever the court refused to order production under § 54-86b. The motion was denied and this denial was made an assignment of error. This issue was already presented to this court in a motion for review, but the motion was denied;
State
v.
Della-Camera,
*564 The defendant’s next claim, of error is based upon the denial of his motion for a mistrial. The motion was predicated upon the alleged prejudicial effect of the court’s announcement to the jury of the guilty plea of a eodefendant, Leo Bruton. Prior to entering a plea of guilty to conspiracy and narcotics charges, Bruton and his attorney had been present at the counsel table for the first three weeks of the trial. DellaCamera, the defendant in this appeal, was also charged with conspiracy to commit the crimes of rape, indecent assault, sodomy, robbery with violence and aggravated assault, and one of his alleged eoconspirators was Bruton. On the same day as Bruton’s plea, October 31, 1969, the court instructed the jury that Bruton’s action was to have absolutely no bearing or reflection upon the charges against the remaining codefendants and that the state’s burden of proof remained the same. 2 At that time, the defendant did not object to the court’s *565 instructions, 3 but on Tuesday, November 4, 1969, counsel moved for a mistrial. The motion was denied by the court and the defendant took an exception.
The defendant relies upon
State
v.
Pikul,
Most jurisdictions hold that it is not error for the trial court to inform the jury during the trial that one or more of the defendants has pleaded guilty, even in a conspiracy case, if proper cautionary instructions are given, and some .authorities even allow the jury to be present when the guilty pleas are entered.
United States
v.
Kahn,
The rationale behind this rule is the prevention of undue speculation and conjecture by the jury concerning the disappearance of a codefendant. See
United States
v.
Johnson,
Those cases which have held that informing juries of guilty pleas was prejudicial error involved situations in which the trial court either erroneously misstated the existence of an admission of guilt or a guilty plea;
Edwards
v.
United States,
The remaining assignments of error received no discussion in the defendant’s brief and are considered abandoned.
State
v.
Brown,
There is no error.
In this opinion House, C. J., and MacDouald, J., concurred; Cotter and Bogdahski, Js., dissented.
Notes
“[General Statutes] See. 5á-86b. bight op accused to examine statements. ... (b) If the prosecution fails to comply with the order of the court, the court shall strike from the record the testimony of the witness and the trial shall proceed unless the court in its discretion shall determine that the interests of justice require that a mistrial be declared.”
“What has happened, this morning is that the defendant Bruton, who is represented by Mr. Mirto — you see there are two vacant chairs. Now, Mr. Bruton has changed his plea as to the second and third counts. You will recall that he was charged in the second count with conspiracy and in the third count with violating the narcotics act. So he has now pleaded guilty to the charge of conspiracy in the second count and he has pleaded guilty to the narcotics violation in the third count.
“Now, I want to make this emphatically clear to you. What Mr. Bruton has done concerns Mr. Bruton only and it has absolutely no bearing or reflection on the other defendants who remain here on trial before you. These defendants have pleaded not guilty. They have not changed their plea. They have pleaded not guilty and the plea of not guilty still stands. They are on trial and, insofar as they are concerned, the State has the burden, as I explained to you in the beginning, of proving their guilt beyond a reasonable doubt. You are here for the purpose of listening to the evidence to determine whether the State has sustained its burden of proof. So actually you will have on trial before you the cases dealing with the defendant DellaCamera, with the defendant Ardito, and with the *565 defendant Esposito, and, of course, I will still have before me the Court case dealing with the defendant Clemente.
“So that there will be no question or misunderstanding, the fact that Mr. Bruton has pleaded guilty in no way changes the burden that rests upon the State to establish the guilt of these remaining defendants, and you are not to draw any inferences as a result of that.”
The defendant contends that there is no support in the record for the court’s finding that all counsel, including DellaCamera’s attorney, agreed to the form of the announcement when the court proposed its explanation in chambers and that no one voiced any objection to the proposal. In view of our disposition of this matter, we need not consider this claim as any correction to which the defendant may be entitled would not alter the result in any way.
