The ten-year gap rule, codified at MCL 777.50, is a foundational limitation on the scoring of Prior Record Variables (PRVs) 1 through 5 of the Michigan Sentencing Guidelines. The rule reflects a legislative judgment that a defendant who has spent ten or more conviction-free years between a prior offense and the commission of the sentencing offense has, by that extended period of law-abiding conduct, earned the right to have earlier convictions excluded from the PRV scoring calculation. Understanding and correctly applying this rule is one of the most consequential — and most frequently litigated — aspects of PRV scoring.
Statutory Text — MCL 777.50(1)
MCL 777.50(1) provides:
"In scoring prior record variables 1 to 5, do not use any conviction or juvenile adjudication that precedes a period of 10 or more years between the discharge date from a conviction or juvenile adjudication and the defendant's commission of the next offense resulting in a conviction or juvenile adjudication."
The rule applies expressly to PRVs 1, 2, 3, 4, and 5. It does not apply to PRV 6 (relationship to the criminal justice system) or PRV 7 (subsequent or concurrent felony convictions).
Step-by-Step Application — MCL 777.50(2)
The Michigan Judicial Institute's benchbook sets forth the proper methodology for applying the ten-year gap rule:
Determine the length of time between the discharge date of the conviction or juvenile adjudication immediately preceding the commission date of the sentencing offense. If the time span is 10 years or more, that conviction or adjudication — and any convictions or adjudications that occurred earlier — must not be counted when scoring the offender's PRVs. MCL 777.50(2).
If the time span between the commission date of the sentencing offense and the discharge date of the most recent prior conviction or adjudication is less than 10 years, that prior conviction or adjudication must be counted in scoring the PRVs. Continue working backward through the defendant's criminal history. MCL 777.50(2).
For each successive prior conviction or adjudication, determine the length of time between the discharge date of that prior conviction and the commission date of the next conviction or adjudication in the chain. Continue this process "until a period of 10 or more years is found or no prior convictions or juvenile adjudications remain." MCL 777.50(2). Any conviction or adjudication preceded by a 10-year gap — measured from the discharge date of the immediately preceding conviction to the commission date of the next offense — is excluded, along with all earlier convictions.
Discharge Date — Definition and Estimation
The discharge date is the date on which the defendant was discharged from the jurisdiction of the court or the Department of Corrections after being convicted or adjudicated. MCL 777.50(4)(b). Where records of the discharge date are unavailable, MCL 777.50(3) provides the method for estimation:
"If a discharge date is not available, add either the time defendant was sentenced to probation or the length of the minimum incarceration term to the date of the conviction and use that date as the discharge date." MCL 777.50(3).
Note carefully: the date the defendant was convicted controls for the purpose of this calculation — not the date the defendant was sentenced. MCL 777.50(3).
Definition of "Conviction" — MCL 777.50(4)(a)
For purposes of the PRVs and the ten-year gap rule, "conviction" is defined broadly under MCL 777.50(4)(a) to include:
- A judgment of guilt entered following a trial or plea;
- Assignment to youthful trainee status under MCL 762.11 to MCL 762.15 (the Holmes Youthful Trainee Act, "HYTA"); and
- A conviction set aside under MCL 780.621 to MCL 780.624 (expungement).
The inclusion of HYTA assignments and expunged convictions within the definition of "conviction" is of critical practical importance: defendants who believe their criminal record has been wiped clean by HYTA or expungement may be surprised to learn that these dispositions remain scorable under the PRVs and are counted for purposes of the ten-year gap analysis. However, not all diversionary dispositions carry this consequence — most notably, MCL 333.7411 dismissals are expressly excluded.
HYTA Status as a Qualifying Conviction
The defendant was adjudged responsible for first-degree home invasion in 2005 but served his term as a youthful trainee under the Holmes Youthful Trainee Act as an alternative to conventional criminal conviction and sentence. The Court of Appeals held that because the defendant was assigned HYTA status in response to having committed the crime of first-degree home invasion — a Class B offense — that status fell within the definition of "conviction" under MCL 777.50(4)(a)(i) and was therefore properly scored under PRV 1. HYTA assignments are, by explicit statutory definition, convictions for all PRV scoring purposes, including the ten-year gap calculation.
MCL 333.7411 Dismissals — Not a "Conviction"
PRV 5 was erroneously scored on the basis of a prior charge of possession of marijuana for which the defendant was assigned to 7411 status, because MCL 333.7411 specifically provides that a discharge and dismissal under that statute does not constitute a conviction and is not an adjudication of guilt. Unlike HYTA status and expunged convictions — both of which are expressly listed within the definition of "conviction" in MCL 777.50(4)(a) — MCL 333.7411 dismissals are not included in that definition. Accordingly, 7411 dismissals are not convictions for any PRV scoring purpose and cannot be used to score PRVs or to bridge a ten-year gap.
The Non-Scorable Conviction Rule — Any Prior Conviction Counts to Bridge the Gap
One of the most frequently misunderstood aspects of the ten-year gap rule is that it operates independently from the separate question of whether a particular prior offense is scorable under the specific PRV at issue. The gap rule asks a different question: was there a conviction-free period of 10 or more years in the defendant's history? Any conviction — even one not scorable under any PRV — can bridge that gap and thereby preserve the scorability of earlier convictions.
This is the controlling published authority on the non-scorable conviction rule. The Court of Appeals held that a prior conviction that is not otherwise scorable under the PRVs may, nevertheless, be considered in applying the ten-year gap rule of MCL 777.50. The defendant had argued that only offenses scorable under PRV 5 could be considered in applying the gap rule for purposes of PRV 5 scoring. The Court rejected this argument, drawing a sharp distinction between the two statutory provisions:
MCL 777.55 (PRV 5) and MCL 777.50 (the gap rule) "serve a common purpose by limiting what prior convictions may be considered, [but] the limitations are different, and the underlying purpose of each respective limitation is obviously different as well." MCL 777.55 through MCL 777.51 to MCL 777.54 "consider the nature of the defendant's prior crimes, whether they are worthy of being scored under the sentencing guidelines, and points are to be assessed based on the number and severity of those offenses." MCL 777.50, by contrast, "addresses the question whether a defendant's prior criminal history should be considered at all because of a period of time spent as a law-abiding citizen." In making this judgment, the Legislature "insisted that the 10-year conviction-free period be . . . free of any convictions, even ones that would not themselves be scorable under the PRVs." A non-scorable misdemeanor therefore bridges any gap that would otherwise exist and preserves the scorability of all earlier convictions.
The following unpublished opinions applied and extended the Butler rule, each reaching the same conclusion that a non-scorable misdemeanor conviction is sufficient to bridge the gap:
Consistent with Butler (which was decided two years later), the Court held that a prior misdemeanor conviction that is not a scorable offense under PRV 5 will nevertheless be considered in determining whether the defendant had a conviction-free period longer than 10 years. A non-scorable misdemeanor bridges any gap that would otherwise exist and preserves the scoring of all convictions from before that offense.
The Court applied the same principle: a non-scorable misdemeanor conviction within the relevant period is sufficient to bridge a potential 10-year gap, thereby preserving the scorability of earlier convictions that might otherwise have been excluded.
Further applying the same rule, the Court found that a non-scorable misdemeanor within the period prevents the formation of any 10-year gap and preserves the scoring of all prior convictions within that chain of criminal history.
The most recent application of the Butler rule in the materials reviewed, again holding that a non-scorable misdemeanor conviction bridges any potential 10-year gap and preserves the scorability of earlier convictions for PRV purposes.
Gap Rule Applied — Cases Finding Improper Scoring
The trial court erred in scoring PRV 2 and PRV 5 of the sentencing guidelines on the basis of convictions that preceded a more than 10-year gap in the defendant's criminal history. Where a qualifying gap exists, all convictions occurring before the gap must be excluded from PRV scoring — the gap operates as a complete bar to earlier convictions, not merely a factor to be weighed.
MCL 777.50 precluded scoring points in PRV 2 where the defendant was discharged from probation on March 18, 1991, and the earliest date for which evidence was presented at trial of the defendant's criminal sexual conduct was March 31, 2001 — a gap of more than 10 years. The Court specifically noted that the gap analysis hinges on the actual offense date, not the later date alleged in the charging instrument. Although the complaint alleged the offense occurred on or about March 7, 2001, the trial evidence established March 31, 2001 as the earliest offense date. The probation discharge date of March 18, 1991, combined with an offense date of March 31, 2001, produced a gap exceeding 10 years by 13 days — sufficient to trigger the exclusion. This case underscores the importance of reviewing the evidentiary record, not merely the charging document, when applying the gap rule.
Ineffective Assistance of Counsel — Failure to Recognize the Gap
Where both trial counsel and appellate counsel failed to recognize a ten-year gap in the prior criminal history that would have precluded the scoring of PRVs 1, 2, and 5, and where the resulting mistake led to a sentence above the appropriate guidelines range, the Court held that counsel provided ineffective assistance of counsel and that the defendant was entitled to resentencing. The error was raised by the defendant himself through a Standard 4 brief filed pro se. This case is a significant reminder that failure to apply the ten-year gap rule correctly is not merely a technical scoring error — it rises to the level of constitutionally deficient performance when it results in a sentence exceeding the correct range. Defense counsel at both the trial and appellate levels have an affirmative duty to identify and litigate applicable ten-year gaps.
The Gap Rule and Habitual Offender Status — A Critical Distinction
A trial court may consider felony convictions that are more than ten years old in determining a defendant's habitual offender status. The ten-year gap rule of MCL 777.50 limits the age of prior convictions that may be counted in scoring the PRVs under the statutory sentencing guidelines, but it does not apply to habitual offender enhancement under MCL 769.10 to MCL 769.12. These are separate statutory schemes with independent limitations. Convictions excluded from PRV scoring by the gap rule may nevertheless support habitual offender enhancement.
The Gap Rule and PRV Applicability
| PRV | Subject Matter | Ten-Year Gap Rule Applies? |
|---|---|---|
| PRV 1 | Prior High Severity Felony Convictions (MCL 777.51) | Yes — MCL 777.50(1) |
| PRV 2 | Prior Low Severity Felony Convictions (MCL 777.52) | Yes — MCL 777.50(1) |
| PRV 3 | Prior High Severity Juvenile Adjudications (MCL 777.53) | Yes — MCL 777.50(1) |
| PRV 4 | Prior Low Severity Juvenile Adjudications (MCL 777.54) | Yes — MCL 777.50(1) |
| PRV 5 | Prior Misdemeanor Convictions (MCL 777.55) | Yes — MCL 777.50(1) |
| PRV 6 | Relationship to Criminal Justice System (MCL 777.56) | No — measures current status only |
| PRV 7 | Subsequent or Concurrent Felony Convictions (MCL 777.57) | No — measures contemporaneous conduct |
Practical Checklist for Defense Counsel
- Obtain complete criminal history including discharge dates — not just conviction dates — for all prior convictions and adjudications. Request jail and probation records if discharge dates are not in the PSIR.
- Identify the commission date of the sentencing offense with precision. Where a date range is alleged, consider what date is supported by the evidence — as People v Ray demonstrates, the evidentiary record may establish a date that differs from the charging document.
- Work backward through the criminal history from the sentencing offense commission date, measuring from each discharge date to the next commission date.
- If a gap of 10 or more years is found, all convictions and adjudications preceding the gap are excluded from PRV 1–5 scoring. The gap is binary: it either exists or it does not — there is no partial exclusion.
- Examine every conviction in the chain to determine if it is a qualifying conviction under MCL 777.50(4)(a). Remember: HYTA assignments and expunged convictions count; MCL 333.7411 dismissals do not.
- Do not overlook non-scorable misdemeanors when searching for gap-bridging convictions, per People v Butler. A traffic misdemeanor or petty theft conviction that is not itself scorable under any PRV nonetheless destroys a potential gap and preserves the scoring of earlier convictions.
- Document and preserve the issue. Per People v Anderson, failure to raise a valid gap rule argument constitutes ineffective assistance of counsel if the error results in a sentence above the correctly-calculated range.
Relationship to Out-of-State and Federal Convictions
The ten-year gap rule applies to all qualifying "convictions" as defined by MCL 777.50(4)(a), which expressly encompasses corresponding out-of-state and federal convictions when those convictions qualify under the applicable PRV statute. An out-of-state conviction that qualifies as a prior high or low severity felony under PRV 1 or PRV 2 by corresponding to a Michigan offense of the appropriate class is subject to the same gap analysis as a Michigan conviction. The gap-bridging effect of non-scorable out-of-state misdemeanors has not been definitively addressed in published authority but the reasoning of Butler would logically extend to them.
