HEFFRON
Docket No. 93374.

*545 State Appellate Defender (by P.E. Bennett), for defendant on appeal.
Before: WEAVER, P.J., and WAHLS and M.J. SHAMO,[*] JJ.
PER CURIAM.
Defendant was convicted by a jury of burning a dwelling house, MCL 750.72; MSA 28.267, and conspiracy to burn a dwelling house, MCL 750.157a; MSA 28.354(1). Following these convictions, defendant pled guilty to being an habitual offender, second offense, MCL 769.10; MSA 28.1082. Defendant was sentenced to 7 1/2 to 30 years imprisonment. Defendant now appeals as of right.
Defendant's house burned down on February 24, 1985, while defendant and his wife and children were away on a vacation. Responding fire fighters were suspicious that the fire had been deliberately set. Several days later, Bennett Patrick, a friend who had been staying at the house while defendant and his family were out of town, confessed to police that he had set the fire at defendant's direction. Defendant also confessed after watching a videotape of Patrick's confession. Defendant pled guilty to burning insured property but later the trial court allowed him to withdraw his plea. After an eleven-day trial he was convicted as charged of burning a dwelling house and conspiracy to burn a dwelling house. He then pled guilty to the habitual offender charge.
I
First, defendant contends that his confession was involuntary because it was improperly induced by a promise of leniency and further that *546 the confession was part of the process of plea negotiations and therefore inadmissible under MRE 410. We do not agree with either claim.
It is clear that MRE 410 requires the exclusion of statements made during guilty plea negotiations. However, upon careful review of the record we conclude that MRE 410 is not applicable to this case because the possibility of a guilty plea was never discussed nor was one offered or accepted. A charge reduction and sentencing recommendation was discussed with defendant in exchange for his "truthful statement." MRE 410 does not cover this situation. See People v Bradley, 106 Mich App 373, 380; 308 NW2d 216 (1981), rev'd on other grounds 421 Mich 704; 365 NW2d 648 (1984).
As for whether defendant's statement was involuntary because it was induced by a promise of leniency, we defer to the trial court's lengthy findings under the totality of circumstances test set forth in People v Conte, 421 Mich 704, 754-755; 365 NW2d 648 (1984). The court found defendant illiterate but that he was adequately advised of his rights orally. The court noted that defendant had prior experiences with Miranda[1] rights and had invoked his rights in the past. The court further found that defendant was not threatened with forty years imprisonment, that defendant and the officer struck a proper bargain, and that defendant's statements were voluntarily made.
This Court in reviewing a trial court's ruling on the admissibility of a confession should examine the entire record and reach an independent determination of voluntariness. However, absent a definite and firm conviction that the trial court erred, the trial court's decision should be affirmed. People v McGillen No 1, 392 Mich 251, 257; 220 NW2d *547 677 (1974). Additionally, where, as here, a determination of voluntariness was largely dependent on the credibility of witnesses, this Court should defer to the trial court's findings. People v Shelson, 150 Mich App 718, 724; 389 NW2d 159 (1986).
Here, the court did not believe defendant was threatened by the interrogating officer with forty years imprisonment. The officer denied making this statement. The officer additionally denied telling defendant that defendant was most likely guilty of conspiracy and denied that defendant asked for an attorney or whether an attorney would be of assistance. We defer to the trial court's ability to judge the credibility of witnesses and defer to the trial court's acceptance of the interrogating officer's testimony. Accordingly, we reject defendant's contention that his confession was induced by a promise of leniency. The trial court did not err in allowing the confession to be admitted at trial.
II
Defendant next argues that the trial court erred by refusing to allow a defense of abandonment to the conspiracy charge.
Defendant testified at trial that, before leaving to visit relatives, defendant told Patrick not to burn the house down. The trial court later ruled that defendant could not use withdrawal as a defense to the conspiracy charge. At the conclusion of trial, the court instructed the jury on the charged offenses of conspiracy to burn a dwelling and burning a dwelling, along with the defense of abandonment to the substantive charge of burning a dwelling. The court also instructed that "abandonment is not a defense to conspiracy."
We find no error in these instructions. The *548 crime of conspiracy is complete upon formation of the agreement  a withdrawal is ineffectual. People v Juarez, 158 Mich App 66, 73; 404 NW2d 222 (1987); People v Thomas Hintz, 69 Mich App 207, 222; 244 NW2d 414 (1976). Contrary to defendant's argument, it is not illogical to allow the defense of abandonment to the substantive offense but not the conspiracy. The substantive offense was not complete until the act of burning the house was carried out, while the conspiracy was complete upon formation of the unlawful agreement to burn the house regardless of whether the act was actually carried out.
III
Defendant next argues that the trial court erred by allowing the mid-trial endorsement of two additional witnesses.
The two witnesses complained of were Patrick, the accomplice, and an expert witness. Both of these witnesses were known to defense counsel prior to trial and the defense had several nontrial days in which to prepare for their testimony. Under these circumstances we do not believe that defendant's rights were adversely affected by the trial court's resolution of this issue. However, we note that in the future, under the new stricter rules set forth in MCL 767.40a; MSA 28.980(1), a prosecuting attorney who wishes to call an unendorsed witness at trial will have to show "good cause" for the late addition.
IV
Defendant's final argument is that his conviction on the habitual offender charge must be reversed because the supplemental information was not *549 filed until more than fourteen days after his arraignment on the underlying charges. The prosecution contended that the fourteen-day rule set forth in People v Sheldon, 412 Mich 565; 315 NW2d 537 (1982), is nonjurisdictional and therefore was waived by defendant's plea of guilty to the supplemental information.
The general rule is that a guilty plea waives all nonjurisdictional defects. People v New, 427 Mich 482; 398 NW2d 358 (1986). In New our Supreme Court discussed the difference between jurisdictional and nonjurisdictional defects:
Today, we hold that a defendant, after pleading guilty, may raise on appeal only those defenses and rights which would preclude the state from obtaining a valid conviction against the defendant. Such rights and defenses "reach beyond the factual determination of defendant's guilt and implicate the very authority of the state to bring a defendant to trial...." [People v] White, 411 Mich [366] 398 [308 NW2d 128 (1981)] (MOODY, J., concurring in part and dissenting in part). In such cases, the state has no legitimate interest in securing a conviction. On the other hand, where the defense or right asserted by defendant relates solely to the capacity of the state to prove defendant's factual guilt, it is subsumed by defendant's guilty plea. [427 Mich 491. Emphasis in original.]
We think it apparent that the fourteen-day rule is jurisdictional and therefore not waived by defendant's guilty plea. The fourteen-day rule is a complete defense at the habitual offender proceeding. It affects the state's authority, as opposed to its capacity, to bring the defendant to trial. People v John Wells, 103 Mich App 577, 586; 303 NW2d 243 (1981). See also People v Hays, 164 Mich App 7; 416 NW2d 358 (1987). Although another panel of this Court reached the opposite conclusion in People *550 v Rashid, 154 Mich App 762; 398 NW2d 525 (1986) (fourteen-day rule nonjurisdictional and waived by guilty plea), that case was decided prior to New. As the supplemental information was not filed until more than fourteen days after defendant's arraignment on the underlying charges, we vacate defendant's conviction as an habitual offender and on remand the trial court should reinstate defendant's sentences on the original charges.
Affirmed in part, reversed in part, and remanded for further proceedings consistent with this opinion.
