v.
DUNCAN.
Calendar No. 25, Docket No. 49,653.
Supreme Court of Michigan.
Decided October 6, 1964.
Frank J. Kelley, Attorney General, Robert A. Derengoski, Solicitor General, and Robert Weinbaum, Assistant Attorney General, for the people.
Kenneth J. Logan, for defendant.
SOURIS, J.
Defendant, while mayor of the city of River Rouge, was indicted in March of 1957 by Judge Bohn of the third judicial circuit sitting as a grand jury[1] charging him with (1) conspiracy to bribe, (2) bribery, (3) conspiracy to extort, and (4) extortion. Trial commenced before a jury, Judge Bowles presiding, on October 22d and was concluded on November 26, 1957, with a verdict of acquittal as to the third and fourth counts of conspiracy to extort and extortion and jury disagreement as to the first and second counts of conspiracy to bribe and bribery. On January 2, 1958, defendant moved the trial court for an order of dismissal as to the first and second counts on the following alternative grounds: (1) that acquittal *653 on the third and fourth counts constituted acquittal (autrefois acquit) on the first and second counts because the facts necessary to prove conspiracy to bribe and bribery, it was claimed, are identical with those needed to prove conspiracy to extort and extortion; (2) that former jeopardy as to the first 2 counts attached upon discharge of the jury, without defendant's consent, after the jury reported to the court that it had been unable to reach a verdict on those counts; and (3) that the testimony of the people's chief witness on the first trial was "in conflict with and repugnant to a charge of bribery if a retrial is had." This motion was notice for hearing on January 17, 1958. We are told, in the stipulation of facts, that the motion "was adjourned from January 17th to January 24, 1958, and thereafter indefinitely", but we are not told upon whose motion such adjournments were granted or whether they were based upon stipulations, nor does the record available to us disclose what occurred.
Nothing further was done of record in this case in 1958, in 1959, nor in 1960 until December, at which time defendant supplemented his earlier motion by demand for discharge on the ground that he had been denied a prompt and speedy retrial in derogation of his State constitutional right thereto (Constitution 1908, art 2, § 19). On December 22, 1960, defendant's motion, as supplemented, was heard and subsequently denied by order filed February 17, 1961. The order of denial set March 20, 1961, as the date for commencement of defendant's retrial on the first 2 counts, but defendant prior thereto filed in this Court an application for leave to appeal from the order of February 17, 1961. Upon our grant of leave, this appeal was taken.
*654 I.
This record discloses no excuse, nor does either party hereto so much as attempt to offer any, for the shockingly protracted delay in bringing on defendant's motion for decision and in retrying defendant for conspiracy to bribe and bribery. The people merely assert that they could not proceed with retrial until defendant's motion was decided, but no explanation is offered why the people made no move to bring that motion on for hearing and decision so that they could, if the motion were denied, proceed with the retrial. Indeed, there is not a word of explanation for the people's failure even to answer the motion except upon oral argument in court. Nor does the defendant, on the other hand, so much as suggest why he sat by idly from January of 1958 until December of 1960 without demanding either decision on his motion or prompt retrial.
Our Constitution of 1908, art 2, § 19, guaranteed defendant a speedy trial. Had he, at any time during the 35 months his unanswered motion gathered dust in the court's files, demanded disposition of his motion so that he could be discharged or promptly retried, he most assuredly would have been entitled to the trial court's order or ours. The cited constitutional provision[2] and the 6 statutory provisions *655 set forth in the margin[3] leave no room for dilution, by judges or prosecutors, of the right of every accused to prompt disposition of criminal *656 accusations. In the face of these commands, we have no doubt that every judge in this State would respond  and quickly at that  to an accused's formal demand on the record for compliance with his constitutionally guaranteed right to a speedy trial.
We have had occasion before to address our attention to such demands. Hicks v. Judge of Recorder's Court of Detroit, 236 Mich 689; People v. Foster, 261 Mich 247: and People v. Den Uyl, 320 Mich 477. Only in Foster was relief denied and there only because, although defendants alleged frequent but informal demands upon the prosecuting attorney and the attorney general for prompt trial or dismissal, the record was barren of any motion therefor filed with the court. Since Foster, it has not been questioned in this State that formal, record entered, demand is required to invoke the constitutional guaranty. While we have been urged on this appeal to forsake this holding of Foster and to rule, instead, that the failure of the defendant to take affirmative action to prevent delay may not, without more, be considered a waiver of his right to speedy trial, we decline so to rule. Our statutes, cited above *657 in the margin, clearly implement and supplement the constitutional grant of right to speedy trial and provide ample means for enforcement of that right. No reason has been suggested to us, nor does any occur to us, for raising a Damoclean threat of dismissal over the heads of our people's prosecutors.
Neither Hicks v. Judge of Recorder's Court of Detroit, supra, nor People v. Den Uyl, supra, supports defendant's contentions. In both cases, the criminal defendants strenuously resisted delay at every step of the proceedings. In Hicks, Hicks was ready for trial on 2 occasions only to have trial adjourned upon the prosecutor's requests therefor, whereupon he applied promptly to this Court for a writ of mandamus to compel the recorder's court to proceed with trial of his criminal case. We ordered an immediate trial within 30 days. In People v. Den Uyl, preliminary examination of the defendants had been adjourned on 7 occasions over 18 months because of the unavailability or recalcitrance of a prosecution witness, each delay having been granted over the defendants' strenuous objections and over their continuing demands for prompt completion of their examination. This Court, while acknowledging (320 Mich at 491) that acquiescence in delay would present a significantly different situation, ordered resumption and completion of the preliminary examination within 60 days or dismissal of the charges against defendants. Thus, in both Hicks and Den Uyl, the defendants strenuously resisted the continuances and demanded prompt prosecution of the charges against them. Here, on the other hand, the record discloses no such resistance or demand. While waiver of a constitutional right may never lightly be inferred, this defendant's litigatory dormancy for 35 months speaks as loudly to us as would his written acquiescence to the people's inexplicable delay.
*658 II.
Defendant's claim that the people are barred from retrying him for conspiracy to bribe and bribery because the evidence required in proof of such offenses is the same as that required to prove the charges of conspiracy to extort and extortion, on which latter charges he has been acquitted, misconceives the authorities upon which he relies. In People v. Cook, 236 Mich 333, relied on by defendant, this Court held that a prior conviction for unlawful possession of liquor barred a subsequent charge of unlawful transportation of the same liquor for the reason that the first offense for which defendant was convicted was a necessary element in, and constituted part of, the second offense charged and both were in fact 1 transaction. In People v. Gessinger, 238 Mich 625, defendant was charged and tried for burglary, grand larceny, and receiving stolen property, but convicted only of the last charge. Upon the trial judge's grant of new trial, defendant filed a motion to quash the first 2 charges, which motion was denied. This Court reversed on appeal because, the offenses charged being separate and distinct offenses, a verdict of guilt of 1 offense without any finding or other jury comment on the other offenses charged constituted acquittal as to the other offenses. Finally, in People v. Powers, 272 Mich 303, the same principle was invoked as to a prior verdict of conviction of the offense of larceny, the jury apparently having made no finding as to the second offense charged and on which defendant was retried  that of receiving stolen property. The Court held that had defendant raised the issue promptly before retrial following the trial judge's vacation of the first conviction, he would have been entitled to have quashed the charge of receiving stolen property, the *659 first jury's silence on that count having constituted acquittal thereof.
Unlike People v. Cook, supra, some of the facts essential to proof of conspiracy to extort and extortion, on which charges defendant was acquitted, were not necessary elements in, and did not constitute part of, the offenses of conspiracy to bribe and bribery. See the statutory provisions set forth in the margin,[4] for violation of which defendant was charged. See, also, People v. Ritholz, 359 Mich 539, 552, 553.
Unlike People v. Gessinger, supra, and People v. Powers, supra, the jury did not remain silent with reference to the charges of conspiracy to bribe and bribery when it returned its verdict of acquittal of defendant on the charges of conspiracy to extort and extortion, as did the juries in Gessinger and Powers with reference to some of the charges there involved, but rather affirmatively announced to the court that it had been unable to agree on a verdict *660 with reference thereto. Thus, in this case, it hardly can be said, as it was in Gessinger and Powers, that silence of the jury constituted acquittal on the charges of conspiracy to bribe and bribery.
III.
Defendant contends on appeal that discharge of the jury under the circumstances disclosed by this record and without his affirmative consent thereto bars his retrial because he has previously been put in jeopardy of conviction of such charges. He invokes the Constitution of 1908, art 2, § 14,[5]People v. Parker, 145 Mich 488; People v. Brosky, 222 Mich 651; and In re Earle, 316 Mich 295; as well as Green v. United States (1957), 355 US 184 (78 S Ct 221, 2 L ed 2d 199, 61 ALR2d 1119); Selvester v. United States (1898), 170 US 262 (18 S Ct 580, 42 L ed 1029), and several other cases from other State jurisdictions. In none of the cases cited is it even suggested that discharge of a jury, without the defendant's consent, for its inability to agree upon a verdict thereby bars subsequent retrial. As a matter of fact, in each of the cases cited it is affirmatively recognized that the doctrine of former jeopardy does not preclude retrial after discharge of a jury "for inability to agree, or for some other overruling necessity". People v. Parker, supra, at 499. See, also, People v. Brosky, supra, at 654; In re Earle, supra, at 302; Green v. United States, supra, at 188; Selvester v. United States, supra, at 264; and United States v. Perez (1824), 22 US (9 *661 Wheat) 579, 580 (6 L ed 165).[6] At most, as in People v. Parker, supra, the inquiry in cases such as the one at bar turns upon determination whether the trial judge was entitled to conclude that the jury in fact was unable to reach a verdict.
Here, the jury began its deliberations at 2:30 in the afternoon of Friday, November 22, 1957. It was excused that afternoon at 4:30. It resumed deliberating on the following Monday at 10, after hearing, at request of counsel, the trial judge restate the parties' theories of the case. At 6 that evening the jury was asked by the trial judge if it had agreed upon a verdict and the foreman replied, "Your Honor, it looks like we can come to no decision". The judge advised the jury that he would require them to continue their deliberations after dinner and, after dinner, the jury did continue its deliberations from 8 that evening until 9:20. At 10 in the morning of the following day, Tuesday, the trial judge supplemented his instructions to the jury with the familiar charge urging agreement if agreement were at all possible, with due regard for the burden of proof and the respective rights of the people and the defendant. This instruction was followed, upon request of the jury foreman, with a repetition of the trial court's earlier instructions relating to the charges of conspiracy to bribe and bribery, whereupon the jury retired for further deliberations. At 3:55 in the afternoon, the jury returned to the courtroom and the following occurred:
"The Clerk: Members of the jury, have you agreed upon a verdict? If so, who will speak for you?
*662 "The Court: Of course you understand, Mr. Foreman, that we wish an expression as to each and every count.
"Foreman Budd: Yes, sir.
"The Court: Go ahead.
"Foreman Budd: We have been unable to reach a verdict on counts 1 and 2. Do you wish the verdict on counts 3 and 4 at this time?
"The Court: Yes.
"Foreman Budd: On count 3 the verdict is not guilty. On Count 4 the verdict is not guilty.
"(The jurors were sworn on their verdict.)
"The Court: Ladies and gentlemen of the jury, again the court wishes, as profusely as it is able, to thank you again for your diligence, the sincerity and the obvious interest that you took in the case and the very serious and considered judgment that you gave to it. The people of the county of Wayne are obligated to you and the court wishes to thank you publicly in this manner.
"The jury in this matter is discharged.
"Mr. Young: Thank you. May I extend my thanks to the jury for their full attention and consideration throughout the case.
"Mr. Gilmore: I already did."
There is no indication in this record, as there was in People v. Parker, supra, that defendant at any time objected to the discharge of the jury or even requested that the judge make further inquiry to determine whether there was any probability that the jury ultimately could agree upon a verdict with reference to the charges of conspiracy to bribe and bribery. It would have been better practice had the trial judge made further inquiry on the record to determine whether any reasonable probability of jury agreement existed. Nonetheless, considering the protracted period during which the jury deliberated, the information conveyed to the court by the jury foreman late Monday afternoon, the supplemental *663 instructions given to the jury by the trial judge on Tuesday morning, and the statement by the foreman Tuesday afternoon that "we have been unable to reach a verdict on counts 1 and 2", we are persuaded, as was the trial judge and, apparently, counsel for defendant at the time, that there was no reasonable probability of jury agreement and, therefore, that the jury properly was discharged. Such discharge, even without defendant's consent, was then authorized by statute in this State.[7] Discharge of a jury for such reason does not bar retrial on the same charges. See People v. Jones, 48 Mich 554, 555, and People v. Taylor, 117 Mich 583, 587.
IV.
Defendant also claims that he is entitled to discharge because the people's principal witness denied, in defendant's first trial, bribing defendant, and it is claimed, therefore, that without such evidence the people cannot prove the charges made against defendant. The contention patently is without appellate. merit.
Conclusion.
The foregoing views compel our affirmance of Judge Bowles' ruling from which appeal was taken. In addition, they reflect the judiciary's commitment to bar procrastination by either party in a criminal case. Because so much time already has elapsed, including more than an ample portion thereof since *664 leave to appeal was granted, and because the criminal charges against defendant involve his performance of a public trust, we consider it essential that this case be tried promptly upon remand or that the charges be dismissed.
Affirmed and remanded for further proceedings in accordance with this opinion.
DETHMERS, KELLY, BLACK, SMITH, and O'HARA, JJ., concurred.
