Why Michigan Appellate Courts Rarely Talk About Credibility — But Still Decide Cases on It

In Michigan appellate courts, one of the most misunderstood concepts among litigants is credibility. This is especially the case when it comes to how appellate judges handle it. At face value, credibility seems like the province of juries and trial judges who watch witnesses testify.

Yet, even though opinions from Michigan appellate courts rarely say the word “credibility," a scan of hundreds of appellate cases over decades reveals a hidden truth. This is, credibility judgments are the silent heartbeat of appellate decision-making. And they're just beneath the surface of legal reasoning.

This article was written by Mark Linton, a long-standing Michigan appeals lawyer. He has a deep understanding of the paradox about credibility in the Michigan appellate system. It has helped him craft winning appellate arguments for his clients for over two decades now. 

Here, he explains why Michigan appellate judges don't explicitly discuss credibility. Still, they decide cases based on the underlying credibility of the trial court record information. He also dives into controlling statutes and court rules. And he breaks down how appellate courts navigate credibility without ever really talking about it.

Credibility and the Appellate Record Rule

The Appellate Record Rule is at the core of every Michigan appeal. This rule states that appellate judges decide cases on what was actually presented on trial (the Record on Appeal). This is contrary to what most people believe. Many think judges decide cases on what might happen if the witnesses took the stand again.

The Appellate Record Rule is a concept reflected in both case law and court rules. Michigan Court Rules (MCR) 7.210(A) limits the appellate record to what was before the trial judge. And it's the first reason judges don't speak directly about credibility on appeal. 

The Record on Appeal includes the transcripts, exhibits, and filings from the trial court. And anything outside the record, including new testimony, new affidavits, and witness reenactments, is generally off limits.

As said numerous times, Michigan appellate courts are not fact-finding tribunals. Therefore, they do not hear new testimony, re-interview witnesses, or revisit first-hand impressions of demeanor. MCR 7.211(C)(1) governs remands for cases where additional fact-finding is necessary.

However, even remand is triggered only when the appellate court cannot decide a legal or factual issue without considering new evidence. Under the mentioned rules, credibility is rarely a standalone error. This is because appellate courts decide cases on the trial court's record of credibility determinations. They never rely on their own subjective arguments. 

How Michigan Appellate Courts Handle Credibility Under Standards of Review

As earlier mentioned, appellate judges don't sit through testimony. And they don't reweigh witness credibility. But how d

o they resolve disputes that implicitly depend on it? Well, the answer lies in the standards of review.

Clear Error for Factual Findings

A party may raise a claim that hinges on factual determinations. And these may include the weight of testimony or which version of events the trial court believed. In such cases, appellate judges use the clear error standard under MCR 2.613(C).

A finding is clearly erroneous when the reviewing court is strongly convinced that there's been a mistake. This is despite evidence being present to support the finding. MCR 2.613(C) directly acknowledges the trial court's superior position to judge credibility. It states: 

“Regard shall be given to the special opportunity of the trial court to judge the credibility of the witnesses who appeared before it.”

In practice, this means that appellate judges accept the trial judge's credibility determinations unless there's a clear error. And they rarely say they're deferring to credibility. Instead, they affirm a factual finding because it's supported by the record. Although another interpretation might also be possible. 

That's how credibility exerts influence without being explicitly discussed.

Abuse of Discretion and Credibility-Inverse Claims

Many decisions turn on how the trial judge handled credibility arguments. These decisions include evidentiary rulings or whether to grant a new trial. Appellate review in these circumstances is for abuse of discretion. 

Abuse of discretion is a deferential standard that gives the trial court more preference over the appellate court. This is in the context of handling nuanced assessments of witness testimony, demeanor, and competing accounts. 

This means that appellate judges may not frame their reasoning as a credibility review. However, abuse of discretion outcomes depend on the trial judge's credibility assessments. 

Why Michigan Appellate Courts Rarely Discuss Credibility

If credibility is so central, why don't appellate judges talk about it? The answer lies in Michigan appellate style and the purpose of written opinions. Published appellate decisions are legal explanations, not transcripts. They focus on rules of law, including statutory interpretation, application of precedent, and procedural requirements.

Openly diving into credibility findings by the appellate court can undermine finality. It can also appear to second-guess juries and trial judges. Plus, it can risk undermining the perception of appellate impartiality. 

As an alternative, appellate courts rely on legal language like, “Supported by competent evidence” or " Not clearly erroneous.” This shorthand allows appellate judges to uphold credibility determinations without criticizing the trial judge's assessment of demeanor or witness reliability. 

This pattern appears across hundreds of published opinions and is not unique to Michigan.

Case Examples of Credibility's Quiet Influence

Real case law shows how credibility lurks beneath the surface of appellate decisions in various ways. Here are two common ways:

Affirming Factual Findings Without Mentioning Credibility 

In the People of Michigan v. Jennifer Marie Curry (2025) case, the Michigan Court of Appeals affirmed a conviction. This is despite the defense counsel arguing that there was insufficient evidence to prove malice. The appellate panel didn't reweigh witness testimony. Instead, it simply noted that the testimony and exhibits provided sufficient evidence to support the verdict. 

The opinion never used the word “credibility." But the trial court's acceptance of testimony was central to the court's holding. Affirming because evidence supports the verdict is a unique kind of reasoning. And it's the appellate equivalent of saying, "We defer to the trial judge's credibility findings.”

Credibility in Discovery and Expert Bias 

In civil cases, the Court of Appeals will sometimes confront credibility indirectly. And the Kathleen Micheli v. Michigan Auto Ins Placement Facility (2022) case is a good example. Here, the court held that records relating to an expert’s history of insurance company work were relevant. This was because they bore credibility or bias. 

Even though the opinion doesn't center on witness credibility, it recognizes that bias affects credibility and, therefore, relevance. In this case, the appellate court consciously connected relevance to credibility. Although it did not center the opinion around a credibility assessment.

The Jury's Role and Credibility Deference

Michigan law strongly protects the jury's role in deciding credibility. A jury verdict will not be disturbed on appeal merely because the evidence could support a different conclusion. Unless the verdict is against the great weight of evidence under MCR 2.611(A)(1)(e), appellate courts will not get involved.

Similarly, trial court judges in bench trials, who do make credibility calls, are entitled to broad deference on appeal. This judicial restraint means appellate opinions rarely dwell on credibility except in most extraordinary circumstances.

Post-Conviction and Newly Discovered Evidence 

Credibility issues can surface more directly in post-appeal contexts. These contexts include MCR 6.508 proceedings for collateral review and challenges involving recantations or witness affidavits. In that arena, a defendant's credibility and the credibility of newly offered evidence become a legal threshold requirement.

For example, in post-conviction motions seeking relief based on newly discovered evidence, a claimant must show actual prejudice. This means there's a reasonable probability of a different outcome. And the assessment of reasonableness often depends on how credible that new evidence would be if introduced. 

Even here, appellate courts will often dodge explicit credibility rulings. Instead, they'll focus on whether the legal elements of the motion are satisfied.

How Mark Linton Harnesses Credibility to Win Appeals

Every appeal turns on something the parties rarely see coming. That is, how the record makes a witness feel to an appellate judge who never met them. Mark Linton is a needle-threading Michigan appellate attorney. He's spent decades learning to read those currents with near-clinical precision. 

He studies transcripts for the small credibility signals that other advocates skip over. He then builds arguments that meet judges exactly where they make those silent decisions.
