The criminal appeals process is one of the least-understood parts of the legal system. Most defendants and their families approach it with assumptions shaped by movies and television — assumptions that are usually wrong, sometimes spectacularly so. The result is missed deadlines, wasted resources, and unrealistic expectations that compromise the strategic thinking the appeal actually requires.
This guide debunks the most common myths about Missouri criminal appeals and explains how the process actually works.
Myth 1: An appeal is a second trial
The most common misconception. An appeal is not a retrial. The appellate court does not hear new witnesses, consider new evidence, or reweigh the credibility of the trial witnesses. It reviews the record of what happened at trial for legal errors.
What that means in practice:
• The appellate court reads the trial transcript and the briefs.
• The appellate court holds oral argument in some cases (typically 15–30 minutes per side).
• The appellate court issues a written opinion months later.
• The appellate court does not see witnesses, does not see exhibits, and does not consider what "really happened."
If the trial jury found the defendant guilty based on evidence that legally supported the verdict, the appellate court will affirm the conviction even if the appellate judges privately would have voted to acquit.
Myth 2: Appeals are quick
Missouri appeals routinely take 12 to 24 months from notice of appeal to opinion. The timeline:
• 30 days after sentencing to file the notice of appeal.
• 3–6 months for the trial court reporter to prepare the transcript.
• 60 days after transcript filing for the appellant's opening brief.
• 30 days for the state's response brief.
• 15 days for the appellant's reply brief.
• 2–6 months waiting for oral argument.
• 3–9 months after oral argument for the opinion.
• If the case proceeds to the Missouri Supreme Court on transfer, add another 12–18 months.
This is not a quick process. Defendants in custody during the appeal are not released pending the outcome unless they qualify for and obtain an appeal bond.
Myth 3: New evidence can be introduced on appeal
It cannot. The appellate court reviews the record of what happened at trial. New evidence not introduced at trial — even powerful evidence — cannot be considered.
The narrow exception is post-conviction relief under Missouri Rule 29.15, a separate proceeding (not an appeal) that allows defendants to raise issues like ineffective assistance of counsel or newly-discovered evidence. Rule 29.15 motions have their own procedures and deadlines — typically 90 days after the appellate mandate — and are different from a direct appeal.
Myth 4: Any error gets the conviction reversed
The appellate court will reverse only if it finds error that was "preserved" (objected to at trial) or "plain" (so obvious it amounts to manifest injustice) and prejudicial enough to have affected the outcome. Most errors at trial don't meet that standard.
The appellate concept of "harmless error" is critical. A judge who incorrectly admitted a piece of hearsay against the defendant won't produce reversal if the appellate court concludes that the rest of the evidence was so strong the hearsay didn't affect the verdict. Defendants whose convictions were "supported by overwhelming evidence" routinely lose appeals based on legitimate trial errors.
Myth 5: Hiring a different lawyer guarantees a better outcome
It can help — particularly if appellate work is a different specialty than trial work, or if the trial lawyer's performance was itself an issue. But the appellate result depends primarily on what's in the trial record. A skilled appellate lawyer working with a clean record can do exceptional work; a skilled appellate lawyer working with a record full of unpreserved errors and waived objections has limited tools.
This is why preserving issues at trial is critical. An objection that was made and overruled creates an appellate issue; an objection that wasn't made gets reviewed only under the "plain error" standard, which the appellate court rarely finds satisfied.
Myth 6: An appeal puts the trial sentence on hold
Generally not in Missouri. Defendants serving prison sentences do not stop serving them while the appeal is pending. The exceptions:
Appeal bond. Missouri courts can grant an appeal bond in some cases, releasing the defendant pending the appellate decision. Bond on appeal requires showing the appeal raises a "substantial question" that, if successful, would reverse the conviction. Granted in a small minority of cases.
Probation cases. Defendants on probation can sometimes have probation conditions modified pending appeal. The probation itself runs.
Fines and costs. Payment is sometimes deferred.
Myth 7: The state can appeal an acquittal
Generally not, due to the Fifth Amendment double-jeopardy clause. The state cannot appeal a not-guilty verdict. The state can appeal certain pretrial rulings (suppression orders, dismissals before jeopardy attaches) but once a jury or judge has acquitted, the case is over.
This asymmetry favors the defendant: if the trial goes well, the state has no appeal. If the trial goes badly, the defendant does.
Myth 8: An appellate reversal means freedom
Sometimes — but more often, reversal means a new trial. The appellate court typically reverses and remands, sending the case back to the trial court with instructions on what went wrong. The defendant then faces a second trial.
Outright reversals (where the conviction is vacated and the case dismissed) happen when the legal error renders any retrial impossible — for example, a finding of insufficient evidence to support the conviction in the first place. These are uncommon.
Myth 9: Federal courts will fix what state courts got wrong
Federal habeas corpus review of state convictions exists under 28 U.S.C. §2254, but it's much narrower than most defendants assume. The federal court can grant relief only when the state-court decision was "contrary to, or involved an unreasonable application of, clearly established federal law" or "based on an unreasonable determination of the facts."
The standard is highly deferential to the state courts. Federal habeas relief is rare and typically follows years of state-court litigation.
What an honest appellate evaluation looks like
A serious appellate evaluation involves reading the trial transcript, identifying preserved issues, assessing the strength of each issue under controlling law, and producing a written probability assessment. It does not involve promises of reversal or claims that the trial lawyer "missed something obvious" without specific identification.
If you're considering an appeal — or if a family member is in custody and you're trying to evaluate options — ask the appellate lawyer:
• What specific preserved issues are in the record?
• What is the historical reversal rate for that type of issue in Missouri?
• What are the realistic outcomes — reversal, remand for new trial, sentence modification, or affirmance?
• Are there post-conviction-relief options (Rule 29.15, federal habeas) that might be more promising than direct appeal?
The bottom line
Criminal appeals are not retrials, are not quick, do not consider new evidence, and don't reverse convictions for harmless errors. The appellate court reviews the trial record for preserved legal errors that were prejudicial enough to affect the outcome. Most appeals do not succeed. The ones that do are built on issues that were carefully preserved at trial, briefed under controlling Missouri law, and argued by counsel who understands the standard of review. Honest evaluation up front is more valuable than promises.
