In this case, the circuit court acted as an appellate tribunal, hearing an appeal on leave granted from a district court conviction of the lesser included offense of impaired driving.
The record indicates timely objection by the defendant to the failure of the prosecutor to pro*475duce or to make adequate excuse for failure to produce a res gestae witness.
Apparently all, i.e., circuit judge, district judge, defense counsel and prosecutor, agree the missing witness was a res gestae witness.
In the trial court, at the conclusion of the people’s proofs, defendant moved to dismiss on the ground that the res gestae witness was neither produced nor any effort made to explain her absence. The district judge denied the motion to dismiss and attempted to solve the problem by a subsequent instruction to the jury that the prosecutor was obliged to produce her, had not done so and that, therefore, it must be presumed her testimony was adverse to the prosecution.
When objection is timely made, that is not good enough. The defense was entitled to the witness or an explanation why she was not produced. An instruction that the testimony would be adverse is not an equivalent substitute. On this record, the trial judge erred in denying defendant’s motion; he could have granted the motion to dismiss or he could have given the prosecution opportunity to produce this missing res gestae witness.
Upon appeal the circuit judge found that the prosecutor’s failure to produce or explain was, in the face of defendant’s timely objection and on the record in this case, fatal to the prosecution’s case, and dismissed the charge. He distinguished his ruling from Robinson where no objection was made at trial. People v Robinson, 390 Mich 629; 213 NW2d 106 (1973).
The prospective portion of the Robinson ruling (i.e., appeals filed after January 28, 1974, as here), requires a defendant to file a motion for new trial where there is a failure to produce a res gestae witness (whether indorsed or unindorsed), a hear*476ing where the prosecution may either produce the witness or explain why he cannot be produced and why he could not be produced at trial, and if produced, examination to determine his testimony regarding the charged offense, and last, findings by the trial court with reasons therefor.
It would appear to this Court that the purpose of the Robinson procedure is to avoid "useless retrials”. Recognizing that there are situations where there may be technical or minimal violations of the rule that requires the prosecutor to produce all res gestae witnesses which do not, in the interest of justice, require retrials, the Supreme Court has devised a procedure to obviate such result. In Robinson the prosecutor apparently produced, or accounted for, all but one of approximately three dozen res gestae witnesses. Rather than a retrial, the Supreme Court required a record regarding the missing or unaccounted-for witness, as a preliminary to deciding whether or not to require a retrial.
In the within case, the district judge has already conducted the equivalent of a Robinson hearing and the circuit judge has made what constitutes Robinson findings. Thus, it was not error to hold that in this case defendant need not move the trial court for a new trial.
There was no error in the finding that she was a res gestae witness and that the prosecutor neither produced her nor explained her absence.
Therefore, in setting aside the jury conviction, the circuit judge is affirmed.
The only remaining issue is whether, in his appellate capacity, the circuit judge could, under those circumstances, reverse and dismiss without a new trial or whether he was limited to reversing and remanding for a new trial. On this record, *477where the jury found the defendant guilty, defendant is only entitled to a new trial on the merits, not a dismissal of the case. The prosecution is entitled to an opportunity to produce the missing res gestae witness.
Affirmed in part and remanded for new trial.
