At a trial pursuant to G. L. c. 278, §§ 33A-33G, the defendant was found guilty and was sentenced on an indictment charging him with rape. The argued assignments of error relate solely to the issue of the defendant’s mental competence at the time of the trial.
We state only those facts necessary to a determination of that issue. The defendant was arraigned on April 28, 1970, in the Municipal Court of the Dorchester District and was *523 committed, pursuant to G. L. c. 123, § 100A, as amended through St. 1957, c. 236, to Bridgewater State Hospital for thirty-five days’ observation. Upon his return to that court on May 29, 1970, a medical report was filed stating that he was competent to stand trial. Following his indictment, the defendant was arraigned in the Superior Court on July 15,. 1970, where, pursuant to his counsel’s request, he was recommitted to Bridgewater State Hospital for thirty-five days’ observation. On August 14, 1970, a second medical report, was filed which stated that he was competent to stand, trial, and the defendant was returned for trial.
The trial began on October 28, 1970. During the selection of the jury, the judge asked the defendant, “Mr. Vailes, are we keeping you awake or anything” to which the defendant responded, “No.” From other evidence we infer that the judge’s question was occasioned because the defendant was resting his head upon his arm and appeared to be falling asleep. At this same time the defendant was also observed buttoning and unbuttoning his shirt and removing his jacket. After the selection of the jury, counsel conferred with the judge out of the hearing of the jury. Following this colloquy at the bench the judge excused the jury and questioned the defendant as to his competency as described below in this opinion.
At the conclusion of the court’s questioning, the defendant’s attorney moved for a mistrial and another Bridge-water commitment for the defendant on the ground that the defendant appeared “to be out of touch with reality right now.” He also informed the judge that the defendant was “not too communicative” with counsel. The judge denied the motion. Prior to resuming the trial on the second day, the judge denied a request by the defendant’s attorney to have the defendant examined by a court psychiatrist. The defendant argues that there were sufficient indications of his incompetency at the time of the trial to require the trial judge to hold a full hearing on the issue and that his failure to do so was constitutional error.
*524
The trial, conviction or sentencing of a person charged with a criminal offence while he is legally incompetent violates his constitutional rights of due process.

Pate
v.
Robinson,
1. There was no error in the denial of the defendant’s motion for a mistrial and for a further psychiatric examination of the defendant, nor was there error in the judge's failure to order an evidentiary hearing on the defendant’s competency. In the circumstances of this case, these matters resided in the sound discretion of the judge and it has not been established that he abused that discretion. The defendant had been observed by psychiatrists for a total period of more than two months during the six months just preceding the trial, and the judge had a right to rely upon the psychiatric report as one of the elements bearing on the issue of the defendant’s competence.

Commonwealth
v.
Devereaux,
*525
2. Cases cited by the defence, in support of the argument that an evidentiary hearing was required, are distinguishable from the case before us because of evidence in those cases of the defendant’s violent or extremely irrational conduct in the court room,
Pouncey
v.
United States,
Judgment affirmed.
Notes
In addition to relying on the due process clause of the Fourteenth Amendment to the Constitution of the United States, the defendant also relies on art. 12 of the Declaration of Rights of the Constitution of the Commonwealth and the Sixth Amendment to the Constitution of the United States as applied to the States.
The judge relied in part on a report dated May 29, 1970, which recommended that the defendant be returned for trial since “ [h]e is aware of the natuie of his charge and its possible consequence and is able to assist his attorney in his own defense.” The report noted that during his observation period the defendant “has been very cooperative and at the present time is in reasonable contact with reality and shows no overt or abnormal mental *525 content,.” A second report, dated August 13, 1970, reached substantially the same conclusion on the issue of the defendant’s competency to stand trial. This report concluded that “the patient has been very cooperative and he gives a relevant and coherent story and knows the nature of his charge and the consequences. He can assist his attorney in his own defense.”
