What Issues Can (and Cannot) Be Raised on Appeal in Missouri Criminal Cases
After a criminal conviction, many people believe an appeal means “getting a second chance” or asking a higher court to re-review the facts of the case.
That is not how criminal appeals work — and misunderstanding this is one of the most common reasons appeals fail before they even begin.
In Missouri, an appeal is limited to specific legal issues. Some problems can be reviewed. Many cannot. Knowing the difference early can save time, money, and false expectations.
This post explains, in plain English, what Missouri appellate courts can review, what they cannot, and how to know whether an appeal is actually worth pursuing.

What a Criminal Appeal Actually Is (and Is Not)
A criminal appeal is not a new trial.
Missouri appellate courts:
Do not hear witnesses
Do not consider new evidence
Do not re-weigh credibility
Do not decide who they believe
Instead, the court reviews the trial record to decide whether legal errors occurred that affected the outcome.
Think of an appeal as a review of the process, not the story.
Issues That Can Be Raised on Appeal in Missouri
An appeal focuses on errors of law. Common appealable issues include:
Legal Errors Made by the Trial Court
Examples include:
Improper admission or exclusion of evidence
Incorrect rulings on motions
Misapplication of Missouri statutes or rules
If the judge applied the law incorrectly, that is often reviewable.
Improper Jury Instructions
Jury instructions are a frequent source of appellate issues.
Examples:
Instructions that misstated the law
Instructions that omitted required elements
Instructions that confused or misled jurors
Even small instruction errors can matter if they affected the verdict.
Constitutional Violations
Appeals can raise violations of constitutional rights, such as:
Denial of the right to a fair trial
Improper restrictions on cross-examination
Unlawful searches or seizures (if preserved)
These issues often overlap with suppression motions filed before trial.
Sentencing Errors
An appeal may challenge:
An illegal sentence
A sentence outside statutory ranges
Errors in applying enhancements
Sentencing mistakes are sometimes correctable even when the conviction itself stands.
Issues That Usually Cannot Be Raised on Appeal
This is where many people are surprised.
“The Jury Got It Wrong”
Missouri appellate courts do not re-decide facts.
They will not:
Re-evaluate witness credibility
Re-weigh conflicting testimony
Decide who was more believable
If the jury believed the state’s witnesses, the appellate court generally accepts that finding.
New Evidence
New evidence usually cannot be considered on direct appeal.
Examples:
New witnesses
New documents
New explanations of events
The appellate court will review claims of insufficient evidence, but it does so “in a light most favorable to the state.”
Issues That Were Not Preserved at Trial
Many appellate issues require that:
An objection was made
The objection was specific
The issue appears clearly in the record
If trial counsel did not properly preserve an issue, appellate review may be limited or unavailable.
Why “Preservation” Matters So Much
Appeals live and die on the record.
Preservation typically requires:
Timely objections
Correct legal grounds stated
Proper motions filed
A complete and accurate transcript
Without preservation, appellate courts often apply a much higher standard — or decline review altogether.
This is one reason appeals require careful, strategic evaluation before filing.
Appeals vs. Post-Conviction Relief — Knowing the Difference
Not every problem belongs in an appeal.
Appeals focus on legal errors visible in the trial record
Post-conviction relief may address issues like ineffective assistance of counsel or matters outside the record
In many cases, the best path forward depends on which procedure fits the issue, not which one feels more urgent.

How to Know If an Appeal Is Worth Pursuing
A strong Missouri criminal appeal usually has:
A clear legal issue
Proper preservation
A meaningful impact on the outcome
A complete and usable record
If the issue is “the verdict felt wrong,” an appeal may not be the right tool — but other legal options might still exist.
Talk to an Appellate Lawyer Before You File
Appeals are deadline-driven and technical. Filing the wrong type of appeal — or filing without a realistic issue — can permanently close doors.
A careful review early can help determine:
Whether an appeal is viable
Whether another remedy makes more sense
How to protect future options
The sooner that review happens, the better.

-
No. Disagreement with the jury’s decision alone is not grounds for an appeal. Appeals focus on legal errors, not factual disagreements.
-
Generally, no. New evidence is typically addressed through post-conviction relief, not direct appeal.
-
Failure to object can limit appellate review. Some unpreserved issues may still be reviewed, but under stricter standards.
-
Appeal deadlines are strict and vary depending on the case. Missing a deadline can permanently forfeit appellate rights.
