See Barker v. Wingo, 407 U.S. 514, 92 S. Ct. 2182, 33 L.Ed.2d 101 (1972). In the current case the length of the delay from appellant’s arrest to the trial was less than four months. In the absence of a showing of prejudice, we cannot say that this is a denial of appellant’s federal constitutional rights.
Second, the comments to Rule 16 state that the intent of the new rule is to overrule the holding of State v. Kananen, 97 Ariz. 233, 399 P.2d 426 (1965), in which the Arizona Supreme Court held that a defendant was not precluded by his failure to make a pretrial suppression motion from objecting to the admission of illegally obtained evidence at trial. Rule 16 is thus applicable to constitutional objections. The ABA Standards Relating to Discovery and Procedure Before Trial (Approved Draft, 1970) states: “At no time has the Court indicated that an accused is entitled to time his constitutional objections on collateral issues according to his whim.”
Finally, in response to the state’s Rule 16 argument, appellant claims that the trial court had a duty to dismiss the case on its own motion. However, as had been shown, the right to a speedy trial is a personal right and can be waived by a defendant.
The criminal rules in effect at the time of appellant’s trial provided that if the court determined that a time limit has been violated, “It may on motion of the defendant, or on its own initiative, dismiss the prosecution with prejudice.” [Emphasis added] Az.R.Crim.P. 8.6 (1973). This language indicates that the decision whether to dismiss the action on its own initiative is in the discretion of the trial court.
We are aware that our Supreme Court in State ex rel Berger, supra (which was decided after the trial in the current case), ruled that the trial court must dismiss the prosecution on the motion of the defendant if the time limits were violated.
The 1975 Rules of Criminal Procedure promulgated by our Supreme Court provide:
Violations. If the court determines after considering the exclusions of Rule 8.4, that a time limit established by Rules 8.2(a), 8.2(c), 8.2(d), 8.3(a), 8.3(b)(2), or 8.3(b)(3) has been violated, it shall on motion of the defendant, or on its own initiative, dismiss the prosecution with or without prejudice.” Az.R.Crim.P. 8.6 (1975).
[Emphasis added].
The comment to this rule simply cites Berger.
We do not read this rule as requiring the trial court to search out possible time violations on its own initiative for this would place an undue burden on the trial court. It is unreasonable to require reversal when the trial court does not perform a function which properly belongs to defendant’s counsel. The comment to the draft of the original rules stated “The committee’s intention is to advise trial judges of their duty to protect the public interest by dismissing delay prosecutions; however, failure of the court to so act upon its own initiative should not be grounds for reversal of a conviction. State v. Crank, 13 Ariz.App. 587, 480 P.2d 8 (1971).” Arizona Proposed Rules of Criminal Procedure (July 15, 1972). We do not think that the 1975 rules intended to abolish this policy consideration and require the trial court to make its own determination before every trial.
Second, the 1975 rules were not in effect at the time of the trial in the current case. Berger only discusses the case where the defendant makes a timely motion; thus, there is nothing in Berger to indicate that under the August, 1973 rules the trial court must dismiss the action on its own initiative.
Finally, both the 1973 and 1975 rules provide that prior to dismissal the
