AFTER REMAND
PER CURIAM.
This case is before us again after remand for resentencing. The prosecutor appeals as of right from the trial court's order denying his motion to resentence defendant. The question presented is whether defendant's absolute discharge from a sentence that may have been invalid precludes resentencing. We conclude that it does not and reverse.
The facts of this case were detailed in our earlier opinion, People v Hill, 192 Mich App 102; 480 NW2d 913 (1991). Defendant pleaded guilty of delivery of more than 50 but less than 225 grams of a mixture containing cocaine, MCL 333.7401(2) (a)(iii); MSA 14.15(7401)(2)(a)(iii). The trial court delayed sentencing, apparently without authority *522 to do so. At the delayed sentencing, on October 23, 1989, the trial court found substantial and compelling reasons to depart from the presumptive minimum sentence of five years' imprisonment and sentenced defendant to one year in jail. The prosecutor filed a motion to correct the sentence, arguing that the sentence was invalid because it was not indeterminate. The trial court granted the motion and resentenced defendant to one to twenty years' imprisonment, again finding substantial and compelling reasons to depart from the five-year minimum.
The prosecutor appealed, contending that the record did not support the finding of substantial and compelling reasons. This Court affirmed in an unpublished opinion per curiam, decided April 5, 1991 (Docket No. 126060).
We then granted the prosecutor's petition to convene a special panel of this Court, pursuant to Administrative Order No. 1990-6, to resolve a conflict with respect to the proper standard for finding substantial and compelling reasons to depart from the presumptive minimum sentence. We held that substantial and compelling reasons for departing from the statutory minimum must be "objective and verifiable," but that the trial court could consider postarrest as well as prearrest factors. Hill, supra, 192 Mich App 115. This case was then remanded for resentencing to allow the new standard to be applied.
However, defendant had been unconditionally discharged from sentence on November 10, 1991, twelve days before this Court's opinion was issued. On remand, the trial court ruled, on the basis of our decision in People v Gregorczyk, 178 Mich App 1; 443 NW2d 816 (1989), that it had no power to resentence defendant. The prosecutor's appeal followed.
*523 In Gregorczyk, the parole board granted the defendant an early discharge from an invalid jail sentence. Subsequently, the defendant was resentenced to probation for life. This Court held that the parole board's action operated as a remission of the invalid sentence and determined that the defendant could not be compelled to serve an additional sentence.
The Gregorczyk decision was recently reconsidered in People v Lamb (After Remand), 201 Mich App 178; 506 NW2d 7 (1993). The defendant in Lamb pleaded guilty of third-degree criminal sexual conduct. He was sentenced to five years' probation, with the first year to be served in jail. Over 2 1/2 years later, the prosecutor filed a motion for resentencing, claiming that the probationary sentence was invalid. The trial court denied the motion, but this Court on appeal held that the sentence was invalid and issued an order vacating the sentence and remanding for resentencing. On the day before the order was issued, the defendant was discharged from probation. Id., p 179. The trial court resentenced the defendant to six months to fifteen years in prison, and the defendant appealed, claiming that his absolute discharge precluded resentencing even though the original probationary sentence was invalid. Id.
This Court disagreed. It found Gregorczyk distinguishable and restricted Gregorczyk to its facts. The two distinguishing features of Gregorczyk were: first, Gregorczyk involved commutation of a sentence by a part of the executive branch of state government; and, second, it was not possible to credit the time served on the defendant's invalid jail sentence against his subsequent sentence of probation. Those separation of powers and double jeopardy concerns were held not to be implicated in Lamb. The Lamb panel concluded that the trial *524 court simply perpetuated its own error by terminating a probationary sentence that it had no authority to impose in the first place. Id., p 181. See also Michigan ex rel Oakland Co Prosecutor v Dep't of Corrections, 199 Mich App 681, 694; 503 NW2d 465 (1993).
Like Lamb, the present case does not involve executive commutation of defendant's original sentence, nor is there any question but that the time defendant has already served can be credited against whatever sentence is eventually imposed. Therefore, resentencing is not precluded. However, in this case, it is yet to be determined whether the sentence originally imposed was invalid. On remand for resentencing, in considering whether there are substantial and compelling reasons for departing from the mandatory five-year minimum term, the trial court may consider all the circumstances in this case that have led to defendant's release from jail.
Remanded for resentencing. We do not retain jurisdiction.
