*682 Levin, J.

The defendants were convicted of first degree murder 1 in separate trials in the summer' of 1967. They appeal, claiming that they were denied their' constitutional and statutory right to a speedy trial. 2

On the same day in May, 1966, that the first-degree murder warrant for the defendants’ arrest was issued, they were arrested in Illinois on an armed robbery charge. They remained in Illinois until January, 1967, when, after having been convicted of armed robbery, they were released by Illinois to Michigan and returned to this State to stand trial.

The United States Supreme Court recently enunciated the standard by which defendants’ claim is to be adjudicated. In Smith v. Hooey (1969), 393 US 813 (89 S Ct 575, 21 L Ed 2d 607, 614), the defendant was, as were the defendants here, detained in one state while facing an untried charge in another state. The court held that, upon the accused person’s demand, the state where the untried charge is pending has “a constitutional duty to make a diligent, good-faith effort to bring him” to trial.

Measured by that “diligent, good-faith effort” standard, the defendants were not denied a speedy trial. No claim is made that the prosecutor did not act diligently after formal extradition proceedings were instituted in the fall of 1966. 3 The delays *683 wbicb occurred after tbe return of tbe defendants to Michigan were attributable to pretrial motions and procedures initiated for tbe most part by tbe defendants. 4

We are persuaded, contrary to tbe defendants’ main contention, tbat tbe Michigan authorities acted with sufficient diligence during tbe period between May, 1966 (when tbe defendants were first detained in Illinois) and fall, 1966 (when formal extradition proceedings were instituted). Tbe chronology of events during this 6-month period follows:

May 11, 1966 — first-degree murder warrant issued at tbe request of tbe Macomb county prosecutor. On tbe same day tbe defendants were arrested in Evanston, Illinois, on tbe Illinois armed robbery charge.

May 13 — a Macomb county assistant prosecutor interviewed tbe defendants in Evanston, Illinois, and learned they wished to be returned to Michigan as soon as possible.

May 23 — tbe assistant prosecutor telephoned Illinois officials who informed him tbat tbe defendants would be tried for armed robbery in Illinois.

*684 June 6 — a letter from Illinois confirmed the May 23 telephone conversation and stated that the defendants would be tried in Illinois on June 23, 1966.

June 23 — -the assistant prosecutor was informed by telephone that the Illinois trial had been postponed until July.

Early July — the assistant prosecutor learned by telephone that the Illinois trial had again been postponed.

July-September — the assistant prosecutor made no further inquiries.

September 8 — the assistant prosecutor received a letter stating that the defendants had pled guilty on September 7, 1966, to the Illinois charge and had been sentenced to serve 2 to 6 years.

September 22 — the assistant prosecutor wrote Illinois authorities giving notice of his intention to begin extradition proceedings.

October 10 — the assistant prosecutor telephoned the governor’s office in Lansing to familiarize himself with extradition procedures.

November 3 — the necessary papers were forwarded from Macomb county to the governor’s office.

During this 6-month period both defendants made several inquiries by mail concerning the delay in extradition. Defendant Ferrazza filed a petition for a writ of habeas corpus with the Macomb county circuit court. 5

The delay in the extradition of the defendants appears to have been unavoidable. The uniform criminal extradition act, which both Illinois and *685 Michigan have adopted, 6 allows a State which has custody of a fugitive on a pending charge to “hold him until he has been tried and discharged or convicted and punished.” 7 Clearly, Illinois had the right to keep the defendants until they were tried in Illinois.

The Macomb county officials early made known their desire to have the defendants returned to Michigan. Every communication between officials of Illinois and of Macomb county during the summer of 1966 indicated Illinois’ intention of detaining the defendants until they had been prosecuted for armed robbery.

The Macomb county officials had every reason to believe that Illinois would not consent to extradition before trying the defendants on the armed robbery charge. While they might have begun formal extradition proceedings at an earlier date, neither their failure to do so nor the few additional weeks’ delay due to the assistant prosecutor’s unfamiliarity with extradition procedures alters our impression upon the whole record that the prosecutor acted with reasonable diligence and in good faith, albeit unsuccessfully, in attempting to obtain custody of the defendants in the late spring and summer of 1966.

This case is distinguishable from the cases decided in other jurisdictions which have been brought to our attention. In most of these cases the record showed total inaction by the prosecution although the defendants had already commenced serving the sentence imposed by the detaining State. In Smith v. Hooey, supra, for 6 years the state of Texas made *686 no effort to bring the accused person to trial other than to send one letter to the detaining authorities. In Pitts v. North Carolina (CA 4, 1968), 395 F2d 182, the State failed for 15 years to take even the “slightest step” to procure a temporary release and a prompt hearing for the accused person. In People v. Winfrey (1967), 20 NY2d 138 (281 NYS2d 823, 228 NE2d 808), no effort was made for 4-1/2 years to obtain the accused person’s presence in New York; pertinent is the following observation of the New York Court of Appeals (p 142): “there is no contention that if such a request [to a sister state] is made and rejected a delay in bringing the prisoner to trial in New York occasioned by his foreign imprisonment would be unreasonable. The point is that in this case no effort of any kind was made.” In People v. Bryarly (1961), 23 Ill 2d 313 (178 NE2d 326), the prosecution had announced its intention to abandon the case after a co-defendant had been acquitted; for nearly five years there was no effort to initiate extradition proceedings. Similarly, see United States v. Reed (DC, 1968), 285 F Supp 738. Cf. State v. Johnson (1967), 13 Ohio Misc 79 (231 NE2d 353).

Our finding that the prosecutor acted with reasonable diligence and in good faith makes it unnecessary for us to decide whether MCLA § 767.38 (Stat Ann 1954 Rev § 28.978), providing for a trial of persons detained in prison within six months, applies to a defendant incarcerated in another state. The Michigan statutes implementing the constitutional right to a speedy trial, 8 as well as the constitutional provision itself, require no more than good faith and prompt action by the prosecution. Cf. People v. Hendershot (1959), 357 Mich 300, 303; People v. Castelli (1963), 370 Mich 147, 153; People *687 v. Williams (1968), 9 Mich App 676, 682, 683, 687; People v. Farmer (1969), 16 Mich App 148, construing a different statute 9 but on principle relevant in the application of MCLA § 767.38 as well.

Defendant Whitney has raised an additional issue concerning the admission into evidence of a black wallet. The wallet was found on Ferrazza when he was arrestéd in Illinois. It contained false identification which had been used by the victim. The defendant now contends that the evidence should have been excluded as irrelevant and unduly prejudicial.

No objection to the admission of the wallet was made at the trial. We recognize that we may, nevertheless, consider the objection now made and, if sufficiently impressed, order a new trial. 10 The evidence of the defendants’ guilt was overwhelming. We are convinced that Whitney would have been convicted even if the wallet had not been admitted in evidence. Accordingly, timely objection not having been made, we decline further to consider this assignment of error.

Affirmed.

After the formal extradition papers were mailed from Macomb eonnty to the governor’s offiee in Lansing on November 3, the assistant prosecutor telephoned Lansing on November 22 in an effort to expedite aetion. The extradition papers were mailed from Lansing to Illinois on November 22. On December 9 the assistant prosecutor telephoned Illinois to prod the Illinois officials and discovered that the required special agreement between the states had not been included. On December 12 the assistant proseeutor persuaded an Illinois official to send the special agreement. This was then forwarded to Lansing. On December 27 this agreement reached Governor Rom *683 ney and on January 4, 1967, the signed agreement was sent back to Illinois. On January 10, the assistant prosecutor telephoned Illinois and was informed that the papers were being sent to the warden of the prison in which the defendants were incarcerated. On January 13, the assistant prosecutor telephoned the warden. On January 18, the assistant prosecutor was informed that the defendants had waived extradition. They were returned to Michigan on January 21.

The defendants were arraigned on the complaint in Maeomb county on January 22, 1967. Counsel were appointed for them on January 23. Preliminary examination was scheduled for February 2. The defendants asked for a 60-day postponement and when the trial judge adjourned the examination for only 2 weeks (until February 14), the defendants brought an action for a writ of superintending control in the circuit court to compel the judge to grant the desired G0-day extension; this motion was denied. On March 10 the defendants were arraigned on the information. On March 27, the defendants moved to adjourn the trial for 60 days; the motion was granted and the trial was set for June 6. On June 5 the defendants moved to dismiss the charges because of the alleged denial of their right to a speedy trial; the motion was denied.

Our disposition of the ease makes it unnecessary to consider or decide whether the defendants’ actions were sufficient to comply with the requirement of a formal demand for a speedy trial. See People v. Williams (1968), 9 Mich App 676, 688; People v. Nawrocki (1967), 6 Mich App 46, certiorari denied 389 US 942 (88 S Ct 304, 19 L Ed 2d 296). Where there has been inordinate delay in bringing an incarcerated accused person to trial, some courts have absolved him of the requirement of filing a demand for a speedy trial. Pitts v. North Carolina (CA 4, 1968), 395 F2d 182, 187; United States v. Chase (ND Ill, 1955), 135 F Supp 230; see, also People v. Darrah (1968), 29 App Div 2d 816 (287 NYS2d 494, 497).
