During a lobby conference with counsel before trial in a jury-of-six session, the trial judge indicated that, should the jury return a verdict of guilty, he would sentence the defendant to a period of committed incarceration. Jonathan L. Lebon, the defendant, had been charged with violation of a “stay away” order issued under G. L. c. 209A. When defense counsel inquired how the court might sentence should the defendant stand trial jury-waived, the judge responded that in such event he would not impose a committed *706jail sentence.1 Thereupon the defendant chose the jury-waived option, was found guilty, and sentenced to six months in a house of correction, suspended for two years.
The defendant has appealed on the ground that the judge coerced the defendant into giving up his right to be tried by a jury. Although the judge engaged in a colloquy with the defendant to determine whether the defendant was intelligently and voluntarily waiving his right to trial by jury, we think that the judge, by offering substantially lighter punishment in return for the defendant not electing a jury trial, so dampened the defendant’s right to trial by jury as to deprive him of it. Accordingly, we reverse the judgment of conviction.
Trial by jury in a criminal case is, of course, a constitutionally protected right. Sixth Amendment to the United States Constitution. Art. 12 of the Declaration of Rights of the Massachusetts Constitution. Indeed, art. 15 of the Declaration of Rights proclaims that the right to jury trial in a civil matter “shall be held sacred” and one may comfortably conclude that in cases where liberty is at stake, the right is not less sacrosanct. Because the right to a jury trial is exalted in our system of justice, a judge may not punish a defendant for exercising his right to trial and the verdict of a jury. Letters v. Commonwealth, 346 Mass. 403, 405 (1963). Commonwealth v. Coleman, 390 Mass. 797, 804 n.7 (1984). Commonwealth v. Ravenell, 415 Mass. 191, 193 (1993). Commonwealth v. Damiano, 14 Mass. App. Ct. 615, 618 (1982). Commonwealth v. Johnson, 27 Mass. App. Ct. 746, 750 (1989), habeas corpus denied sub nom. Johnson v. Vose, 927 F.2d 10 (1st Cir. 1991). Commonwealth v. Ford, 35 Mass. App. Ct. 752, 757-758 (1994).
Of the cases cited in the previous paragraph, the Coleman, Ravenell, Damiano, Johnson, and Ford cases present the *707more familiar scenario in which the defendant, after sentencing, protests that the judge has imposed harsher punishment because the defendant elected to stand trial rather than plead guilty. In such instances, the courts have been at pains to observe that a stiffer sentence after trial than may have been offered in a plea bargain “does not, by itself, betoken vindictiveness,” not least because “[t]he willingness of the defendant to admit guilt [and so taking the first step toward rehabilitation] ... is a proper factor in more lenient sentencing.” Commonwealth v. Johnson, 27 Mass. App. Ct. at 750-751, and cases and authorities there cited.
To tell a defendant straight out that punishment will be more severe if he elects to stand trial is coercion as matter of law. Letters v. Commonwealth, 346 Mass. at 406. That principle applies, perhaps even more cogently, to an election whether to be tried by a jury. When a defendant opts to plead or stand trial, as we have observed, admission of guilt is a socially positive act entitled to reward. When the question is whether to exercise the right to trial by jury, the defendant has remained steadfast in the position that he is not guilty and desires to stand trial. To then lay before the defendant the prospect of enhanced punishment should he claim a jury presses the defendant to abandon the right that the State and Federal Constitutions so sanctify.
After the defendant in the instant case notified the trial judge that he wished to waive his right to trial by jury, the judge engaged the defendant in the sort of colloquy suggested in Ciummei v. Commonwealth, 378 Mass. 504, 508-510 (1979). See also Commonwealth v. Schofield, 391 Mass. 772 (1984). Among the questions the judge put was one in which he asked: “Has any one forced you or promised you anything to give up your right to a jury trial?” The defendant answered, “No.” We have considered whether by so responding (as well as more generalized responses in the colloquy that he was satisfied to be tried by the judge without jury), the defendant waived not only a jury but the right to argue on appeal that he had been coerced. Our learned col*708league observes in his dissent that “a deal is a deal” but a deal is not always a deal when one side has all the cards.
If a defendant elects to waive a jury out of fear of enhanced punishment if he is found guilty by a jury rather than a judge, it is artificial to expect him to protest to the same judge who has put pressure on him that he is making his choice because of that pressure. In such a situation it is the judge, albeit with the understandable motive of moving the trial list, who has put the defendant to a choice, that is apparently free but in fact is not. It is not reasonable, and, therefore, not consonant with justice to require the defendant to make a simultaneous constitutional challenge when the consequence of the challenge may be a trip directly to jail. In this case, for example, the risk was great that the judge’s response to such a challenge (quite properly) would be to opt for a committed sentence whichever avenue the defendant chose.
On the view we have taken of the case, we need not consider the other issues raised by the defendant. For the reason that the effect of the choices offered by the judge coerced the defendant into abandoning his right to a trial by jury, the judgment is reversed, and the defendant may have a new trial.
So ordered.
There was no stenographic record of the lobby.conference. The parties prepared an agreed statement of what had been said in the lobby conference, purportedly under Mass.R.A.P. 8(d), 378 Mass. 934 (1979). Although the trial judge did not expressly “approve” the agreed statement, he allowed a motion to expand the trial record to include the statement. We think that amounts to a de facto approval of the agreed statement. The issue raised by the statement, therefore, is properly before us.
