Dеfendant was convicted on October 2,1981, after trial by jury, of two counts of aggravated assault in violation of 13 V.S.A. § 1024 and one count of kidnapping, 13 V.S.A. § 2401. On appeal, defendant raises three claims of error: (1) whether the trial court lacked jurisdiction over defendant because it allegedly dismissed all three charges and the State failed to refile them; (2) whether the time elapsed bеtween incarceration and trial infringed defendant’s constitutional right to a speedy trial; and (3) whether the trial court erred in denying defendant’s motion for a mistrial because of prejudicial statements made before the jury by the prosecution’s psychiatrist. We disagree with defendant’s claimed errors and affirm the conviction.
*399 On March 3, 1980, defendant picked up a woman hitchhiking home from work sometime after 9:00 p.m. As they drove east on Vermont Route 4 toward Bridgewater, defendant asked the hitchhiker if she would “do him a favor” and offered her $100 if she would acquiesce. She said no and asked to be let out of the car. Defendant pulled into a parking area and the victim tried to flee. The two struggled, but the six foot seven inch defendant subdued the five foot tall woman by hitting her arоund the head and shoulders, and then choking her into unconsciousness.
When the woman regained consciousness, she was lying on the floor of the car, covered with a blanket or jacket. Defendant was again driving, now with one hand on the woman’s back, holding her on the floor and admonishing her to keep her head down and not to look at him. Defendant told her he would release her when he found a dirt road to drive down so that he could have more time to escape. Because she was fearful of leaving the travelled highway, the woman grabbed the steering wheel, causing the car to swerve out of control. Defendant then agreed to let her out of the car right away. After slowing slightly and waiting for traffic to pass, defendant shoved the woman out the car door and sped away. She made her way to a nearby inn and contacted the Vermont State Police.
Two days later, the State filed an information charging defendant with kidnapping, two counts of aggravated assault, and driving with license suspended. Defendant pled not guilty by reason of insanity, and a psychiatric examination was ordered. Defendant was sent to the Vermont State Hospital for examination, and as a result of that evaluation, the trial court, on April 24, 1980, ordered defendant hospitalized, pursuant to 13 V.S.A. § 4822.
I.
Defendant’s first issue on appeal is that the trial court lacked jurisdiction because, “[o]n April 24, 1980, all pending charges against [defendant] were dismissed without prejudice.” No new charges were ever brought by the State.
Defendant is correct that a convictiоn is invalid when, due to an entry of nolle prosequi or a dismissal by the court, defendant is one against whom no charges are pending.
State
*400
v.
Dopp,
127 Vt.
573,
574-75,
State’s Attorney: Just for the record, Your Honor, this is the same charge that was originally brought [in March of 1980]. This has not been a subject of dismissal and then a refiling.
Defendant’s Trial Attorney: Right, it’s been pending all along, Your Honor.
Court: Since March of 1980?
State’s Attorney: It remained pending during the course of hospitalization, Your Honor.
The record is cleаr that of the four offenses charged by information in March of 1980, only one offense — driving with license suspended — was dismissed by the State. That occurred on July 20, 1981. Bail requirements in connection with the remaining three charges were never rescinded by the court. There is no merit to defendant’s challenge to the jurisdiction of the trial court.
II.
Defendant’s second claimed error is that his Sixth Amendment right to a speedy trial was denied by the delay of almost twenty months from the time of his original incarceration to the date of trial. Defendant places primary reliance on 12 V.S.A. App. VIII, A.O. 5, this Court’s administrative order
*401
designed to insure prompt and efficient disposition of criminal cases, and
State
v.
Franklin,
Analysis of a speedy trial issue in Vermont requires consideration of the four factors outlined by the United States Supreme Court in
Barker
v.
Wingo,
A. Length of Delay
Although the first factor to consider, length of delay, is not dispositive of the constitutional question, and at most operates as a triggering device for further inquiry,
Barker
v.
Wingo, supra,
Defendant was arraigned March 5, 1980, and immediately remanded to the custody of the Department of Mental Health for a determination of his competency to stand trial. 13 V.S.A. §§ 4814, 4815. Preliminary psychiatric evaluations were completed and prеsented to the court on April 24, 1980. As provided by A.O. 5, § 4 (a), delay occasioned by the need to determine competency to stand trial is excluded from consideration.
Also excluded are the delays accompanying pretrial motions and those resulting from defense-requested continuances. Thus, the period from July 1, 1981, to September 30, 1981, the date of trial, is not to be considered in сomputing time. During that three-month period, defendant filed a motion to dismiss and then requested two continuances. Id. at §§ 4(a) *402 and (b). The period remaining, from April 24, 1980, through July 1, 1981, is therefore the maximum time frame against which this Court must balance the three remaining Barker factors: reason for delay, assertion of right to speedy trial, and prejudice to defendant. This time thus equals fourteen months and six days, not the twenty months claimеd by defendant.
B. Reason for Delay
During the entire period of delay, defendant was in the custody of the Department of Mental Health and was a patient at the Vermont State Hospital in Water bury. He had been found by the trial court to be competent to stand trial, but “sexually very dangerous . . . [and without] . . . sufficient control over his actions to comply with the law.” The court therefore ordered him hospitalized as a “person in need of treatment” and a “patient in need of further treatment,” 18 V.S.A. §§ 7101(16) and (17) ; as such, during his hospitalization he had “the same status, and the same rights [as a person subject to involuntary civil commitment], including the right to receive care and treatment, to be examined and discharged, and to apply for and obtain judicial review . . . .” 13 V.S.A. § 4822 (b) (incorporating by specific reference the involuntary civil commitment procedures of 18 V.S.A. §§ 7611-7622).
Defendant directs our attention to
State ex rel. Haskins
v.
County Court of Dodge County,
However, here we are not faced with an incompetent defendant, but a competent one. At the April 24,1980, hearing, the court heard testimony from the examining psychiatrist and found defendant competent to stand trial. 13 V.S.A. § 4817. Nevertheless, medical testimony at the hearing also indicated that defendant was insane at the time of the offense, thus triggering the need to decide whether defendant should be hospitalized.
Id.
§ 4820 (1). Consequently, and with the agreement of all parties, defendant was remanded to the Department of Mental Health for an indeterminate period. 13 V.S.A. § 4822 (a). But see
State
v.
Mayer,
[D] ismissal for lack of speedy trial in cases such as these [where defendant is incarcerated due to mental disease or defect prior to an adjudication of guilt] would hinge upon *404 a court’s determination of whether the delay resulted in a prejudice tо the defendant and would deny the constitutional right to a fair trial.
Dodge County, supra,
As mentioned above, perhaps the most important reasons for the delay in this case are the acquiescence by defendant to hospitalization and the apparent willingness of the State to let defendant remain in a secure facility without any attempt to schedule promptly a trial on the merits. In this regard, the State’s position did not change until defendant began to take steps to secure his own release from the hospital and to alter his involuntary commitment status. At the April 24 hospitalization hearing, both the State and defendant made their positions clear:
Defense attorney: Judge, before we proceed, it is the position of the defendant before the Court today, . . . that wе do not contest the hospitalization, as requested by the State. We are prepared to hear the evidence; and the defendant is prepared to state that to the Court. If the Court so wishes.
State’s attorney: I would ask that the Court make that inquiry of the defendant.
Defense attorney: But we wished to state that, before the hearing, to explain our position to the Court.
The Cоurt: Mr. Williams, it is my understanding from what your attorney said, it is your desire not to contest the hospitalization hearing?
Defendant: Yes.
The hearing ended a short while later on a similar note.
Defense attorney: Consistent with our prior position, Your Honor, we do not contest the order for hospitalization, as requested by the State’s Attorney, in this matter.
*405 The Court: Let me make an inquiry. Do you have any witnesses, at this time?
Defense attorney: We do not, Your Honor.
The Court: Do you wish to ... Do you, or your client, wish to make any argument, at this timе?
Defense attorney: We do not, Your Honor.
Thus, the reasons for the delay in this case are clear: defendant’s consent to the hospitalization, and the State’s satisfaction with the arrangement. See A.O. 5, § 4. We turn, then, to the third factor, defendant’s assertion, or lack thereof, of his right to a speedy trial.
C. Assertion of the Right
Appellate review of defendant’s speedy trial claim is hampered by defendant’s admitted failure to assert in any manner this claim below, at least until his motion to dismiss in July of 1981. But see
State
v.
Unwin, supra,
However, we have before us a defense motion to strike portions of the supplemental printed case filed by the State. Twenty-one of the twenty-nine challenged documents do not come from the original papers and exhibits on file in the trial court. Rather, they are either part of the file of a separate, though related, case or come from the files of the state’s attorney. Although this Court has authority to suspend the appellate rules for just cause under V.R.A.P. 2, defendant’s motion is otherwise well grounded in that V.R.A.P. 10 (a) clearly demands the exclusion of these twenty-one documents. Therefore, we must grant in part defendant’s motion to strike * and dis *406 regard twenty-one of the State’s twenty-nine submissions in its printed case. This Cоurt has in the past discussed the appropriate route for admission of the evidence the State now seeks to proffer through the “back door” of a printed case.
Docket entries or orders from another proceeding, however material, are not properly included in the record of this case on appeal. If important to the record in this cаse being tried, they may be introduced into evidence, or judicially noticed by the court pursuant to stipulation. Otherwise, they are not properly before the court.
Pope
v.
Birchwood Manor Corp.,
Here, however, the speedy trial claim was not raised below by defendant, the State, or the court on its own motion. Consequently, there was little opportunity or need for either side to tender the various excludеd documents. Thus, the record in its present form provides scant illumination on the answers to now very important questions concerning why, after the initial determination of defendant’s competency to stand trial in April of 1980, the case did not then proceed immediately to trial. The record which is properly before us suggests strongly the acquiescence of all parties to the treatment of defendant in Waterbury. Nevertheless, we note that putting the trial of three serious felony charges indefinitely on the back burner flirts with a variety of constitutional taboos. Were defendant able to show prejudice from the delay and the assertion of his rights below, this case would take a much different posture. As defendant concedes his failure to assert the right below, we turn then to thе question of prejudice, the “most important factor to consider in analyzing speedy trial issues.”
State
v.
Bristol,
*407 D. Prejudice to Defendant
Defendant rests his claim of prejudice on the shoulders of
State
v.
Franklin, supra,
which he reads as creating unrebutted “prima facie prejudice” where the State has not presented “good cause for an extension of time for trial . . . .” (quoting A.O. 5, § 3). But see
Barker
v.
Wingo, supra,
As defendant has failed to present any specific claims of prejudice,
State
v.
Unwin, supra,
[B] arring extraordinary circumstances, we would be reluctant indeed to rule that a defendant was denied this constitutional right [to a speedy trial] on a record that strongly indicates, as does this onе, that the defendant did not want a speedy trial.
Barker
v.
Wingo, supra,
III.
Defendant’s final claim of error is that the trial court abused *408 its discretion in denying defendant’s motion for a mistrial after a psychiatrist called by the State allegedly interjected prejudicial information about defendant’s possible discharge from the hospital.
The transcript reveals that a nonresponsive answer to a question by the state’s attorney immediately drew an objection from defendant. Following a bench conference in which both the State and defendant agreed that a discussion of defendant’s attempts to get out of Waterbury, by demanding a review of his treatment, would be prejudicial, the State was allowed to аsk leading questions to steer his witness away from such an area. However, on cross-examination, defense counsel reopened that area of inquiry. The expert witness answered a question by making an oblique reference to the prejudicial material, whereupon defendant immediately objected to the answer that he received to his own question. No other curаtive action was ever requested by defendant.
At the conclusion of the expert’s testimony, defendant made a motion for mistrial. The trial court found that (1) the prejudicial answer came in because of a poorly framed question by the defense attorney, (2) no motion to strike or request for a limiting instruction was timely made, and (3) the court had specifically warned both attorneys tо avoid that area in the testimony, a warning defendant disregarded at his own peril.
We cannot say that the trial court abused its discretion in so ruling.
Judgment affirmed.
Notes
