The defendant raises one issue in his appeal from his convictions of rape of a child and indecent assault and battery on a child under fourteen. The victim was the defendant’s daughter, who was eight at the time of the crimes.
As part of a conscious trial strategy to present no defense, defense counsel seasonably raised, by written motion and orally, his request that the trial judge not instruct the jury as tо the defendant’s right not to testify. The defendant did not testify. In spite of the defendant’s objection, the judge in *745 structed the jury concerning the defendant’s right not to testify, erroneously believing that he was required to give such an instruction. 1 We conclude that this was not reversible error but annоunce for the future that, when a defendant seasonably requests that the jury not be instructed concerning the defendant’s right not to testify, the judgе must accede to that request.
There was no violation of the Fifth and Fourteenth Amendments to the Constitution of the United States in this casе. The Supreme Court has said that a judge must give an appropriate instruction concerning a defendant’s right not to testify if the defendаnt requests it.
Carter v. Kentucky,
We have not dealt previously with the question whether a defendant has the right to dеcide that no instmction shall be given concerning his decision not to testify. We have found no error where a judge gave such an instmction in the absence of any request for it. See
Commonwealth
v.
Bumpus,
We have no hesitancy in announcing for the future that it will be revеrsible error if a judge instructs the jury concerning a defendant’s right not to testify when the defendant has requested that no such instruction be given. 2 It is difficult to determine whether such an instruction is beneficial to a particular defendant or to defendants as a group. On the one hand, it warns the jury against drawing inferences adverse to the de *747 fendant from his not testifying. On the other hand, such an instruction may focus the jury’s attention on the question why the defendant decided not to assist the jury in their fact-finding function. The rule we announce is not constitutionally based. It is simply a statement of the law of the Commonwealth for cases tried after this date that the defendant has the choice. 3
We decline, however, to apply this new rule of law to the defendant in this case to grant him a new trial. The charge on the defendant’s failure to testify was a correct statement of the law and contained no intimation that the defendant was hiding important information. 4 The defendant’s decision not to testify created the basic problem because of the jury’s possible adverse reaction to his failure to deny the charges under oath. There is no way to tell whether the giving of a cautionary instruction was additionally prejudicial to the defendant in any significant way. It also follows, therefore, that the defendant cannot demonstrate that he was prejudiced by the chargе given. We have considered the evidence and see no reason why his young daughter should be required to testify again about his sexual misconduct. Considering the evidence in the case we believe that the jury would have inevitably reached the same result if the judge had omitted the challenged instruction. 5 Thus, even if *748 we were to conclude that the defendant had the right under the State Constitution to have no instruction given concerning his failure to testify, the giving of that instruction, over the defendant’s objection, was harmless error.
Judgments affirmed.
Notes
The judge told the jury: “We have а statute in this Commowealth which states the defendant in a criminal trial shall be allowed to testify but his neglect or refusal to testify shall not crеate any presumption of guilt against him. If he did not testify, no unfavorable inference can be drawn and certainly no inference оf guilt.”
Some States have reversed convictions in cases where the judge gave such an instruction over the defendant’s objection. See, e.g.,
Russell
v.
State,
If there аre multiple defendants, under Federal constitutional requirements the judge will have to give the instruction as to any defendant who requests it (see
Carter v. Kentucky,
The instruction did not speak in terms of the defendant’s right not to “incriminate” himself. Although we once impliedly approved a charge that referred to a defendant’s “constitutionаl right not to incriminate himself’
(Commonwealth
v.
Morrissey,
Because there is no clear sense оf prejudice or disadvantage to the defendant arising from the giving of the charge, it is not significant that the judge erroneously thought he had tо give the charge, even over the defendant’s objection, *748 when in fact he had discretion not to give it. We have expressed a different view when a judge having discretion on a matter that could adversely affect a defendant in a significant way denies that he has that discretion and rules against a defendant. See Commonwealth v. King, ante 691 (1984) (discretion as to the admission of evidence of prior convictions).
