v.
WESTON
Docket No. 65995.
Supreme Court of Michigan.
Decided May 25, 1982.
Frank J. Kelley, Attorney General, Louis J. Caruso, Solicitor General, Robert L. Kaczmarek, Prosecuting Attorney, and Kay F. Pearson, Assistant Prosecuting Attorney, for the people.
Nora J. Pasman, Assistant State Appellate Defender, for defendant.
PER CURIAM:
MCL 766.4; MSA 28.922 requires that a magistrate "set a date for a preliminary examination not exceeding 12 days" after the day on which a person charged with a crime is brought before the magistrate. There is no question in this case that the date set was more than 12 days after the defendant appeared in the district court. The magistrate was therefore required to discharge the defendant without prejudice to the prosecutor's right to later initiate an action against him.
I
The defendant was arrested on September 4, 1978, and charged with armed robbery[1] and possession of a firearm during the commission of a felony.[2] He appeared before the district judge on *373 September 6, and the preliminary examination was scheduled for September 20, 1978, fourteen days later. It was adjourned until October 4, 1978. At the beginning of the examination on that date, defense counsel said:
"Defense is ready, your Honor. I would however like to point out to the court that preliminary examination in this matter was originally scheduled on September 20, 1978, the matter was adjourned by the court. This was not at the request of Mr. West, and [sic, he?] would have preferred to proceed under the 12-day rule."
The defendant was nevertheless bound over on both charges. The felony-firearm charge was dismissed by stipulation before trial. A jury subsequently found the defendant guilty of armed robbery.
The defendant continued his challenge to the scheduling of the preliminary examination in the Court of Appeals. That Court found no error requiring reversal because "we are not persuaded that defendant suffered any prejudice due to the delay". After the defendant filed a request for review[3] in this Court, we issued an order directing the prosecutor to show "why the defendant's conviction should not be reversed because of the delay in conducting the preliminary examination". The prosecutor's response and a reply by the defendant are now before us.
There is no explanation on the record why the preliminary examination was not initially scheduled until the 14th day or why it was adjourned *374 for an additional 14 days.[4] The defendant was incarcerated during the entire period.
II
MCL 766.4; MSA 28.922 provides:
"The magistrate before whom any person is brought on a charge of having committed a felony shall set a day for a preliminary examination not exceeding 12 days thereafter, at which time a magistrate shall examine the complainant and the witnesses in support of the prosecution, on oath in the presence of the accused, in regard to the offense charged and in regard to any other matters connected with the charge which the magistrate considers pertinent."[5]
The legislative significance attached to a prompt preliminary examination is underscored by the strict limitation on any delay contained in MCL 766.7; MSA 28.925:
"An adjournment, continuance, or delay of a preliminary examination shall not be granted by a magistrate except for good cause shown. A magistrate shall not adjourn, continue, or delay the examination of any cause by the consent of the prosecution and accused unless in his discretion it shall clearly appear by a sufficient showing to the magistrate to be entered upon the record that the reasons for such consent are founded upon strict necessity and that the examination of the cause cannot then be had, or a manifest injustice will be done. An action on the part of the magistrate in *375 adjourning or continuing any case, shall not cause the magistrate to lose jurisdiction of the case."
The examining magistrate is to bring the preliminary examination "to a final determination without delay except as it may be necessary to secure to the accused a fair and impartial examination". MCL 766.1; MSA 28.919.
We have not previously addressed this issue. The Court of Appeals has developed the principle that noncompliance with MCL 766.4; MSA 28.922 is not error requiring reversal unless the defendant can show prejudice from the delay. Despite its repeated application,[6] none of the cases provide a reasoned basis for the "no prejudice/no reversible error" rule. One of the earlier cases[7] cited People v Donald D Williams, 2 Mich App 91; 138 NW2d 498 (1965), but Williams discussed prejudice in the context of denial of a speedy trial claim. The analysis of a speedy trial issue in which the relief granted is the defendant's discharge and a bar to further prosecution[8] is far different from the analysis here in which the relief to be granted is the defendant's discharge without a bar to further prosecution.[9] Another of the early Court of Appeals cases[10] relied on the miscarriage of justice *376 statute.[11] We are unable to apply this more general statute in the face of an unqualified statutory command that the examination be held within 12 days.
A preliminary examination functions, in part, as a screening device to insure that there is a basis for holding a defendant to face a criminal charge.[12] A defendant against whom there is insufficient evidence to proceed should be cleared and released as soon as possible. The notion that a presumptively innocent defendant should remain in custody until a convenient time arrives for the magistrate to conduct the preliminary examination is exactly what the Legislature precluded in MCL 766.1; MSA 28.919.
The failure to comply with the statute governing the holding of the preliminary examination entitles the defendant to his discharge. Since literal enforcement of the statute "does not affect the integrity of the fact-finding process",[13] we give the decision prospective effect; it applies to this case and to a defendant arraigned on a felony arrest warrant after the date on which this opinion is filed.
In lieu of granting leave to appeal, pursuant to GCR 1963, 853.2(4), we reverse the defendant's conviction and order his discharge from custody, without prejudice to the prosecutor's right to reinstate a prosecution against him.
COLEMAN, C.J., and KAVANAGH, WILLIAMS, LEVIN, FITZGERALD, RYAN, and BLAIR MOODY, JR., JJ., concurred.
