What Grounds Strengthen a Criminal Appeals Case?

Wolfe Law Group July 12, 2025

A criminal conviction in Ohio can have far-reaching consequences—from loss of freedom and employment opportunities to damage to one’s reputation and civil rights. 

Fortunately, Ohio law allows individuals to challenge wrongful convictions or unfair trial outcomes through the appellate process. While not every verdict can or should be appealed, certain legal grounds significantly increase the strength of a criminal appeal.

Wolfe & Mote Law Group, LLC is a criminal defense firm in Columbus, Ohio, that represents individuals who believe that legal errors or misconduct occurred in their trial or sentencing. Understanding what strengthens a criminal appeals case under Ohio law is crucial for anyone pursuing post-conviction relief.

Criminal Appeals in Ohio

A criminal appeal is not a new trial. It does not involve presenting new evidence or calling witnesses. Instead, an appellate court reviews the trial court’s proceedings to determine whether legal mistakes affected the outcome. Appeals are decided based on the trial transcript, written briefs submitted by attorneys, and oral arguments if granted.

Ohio courts of appeals don’t reconsider facts already determined by a jury. Rather, they evaluate whether the trial was conducted fairly and in accordance with the law. 

If the appellate court finds that a legal error occurred and that the error had a substantial impact on the verdict or sentence, it may overturn the conviction, modify the sentence, or order a new trial.

Preserving Legal Issues for Appeal

For an appellate court to consider a legal issue, it must have been preserved during the trial. This means the defense must have objected to the error or misconduct at the time it occurred. If a defense attorney fails to object or raise an issue, the court may still consider it under the doctrine of "plain error," but that threshold is harder to meet.

Working with legal professionals experienced in criminal defense law can make a difference in preserving legal issues for appeal and crafting strong arguments in post-conviction proceedings.

Strong Grounds for a Criminal Appeal in Ohio

Certain types of legal errors or violations strengthen the case for a criminal defense appeal. Not all mistakes lead to a reversal, but when those errors clearly violate constitutional or procedural rights, the chances of success increase.

Below are some of the most compelling grounds that can support a criminal defense appeal in Ohio:

1. Ineffective Assistance of Counsel

The U.S. Constitution guarantees the right to effective legal representation. If a defense attorney's performance falls below a reasonable standard and prejudices the outcome, the conviction may be overturned. Examples include failing to investigate key evidence, missing filing deadlines, or not calling important witnesses. Ohio courts apply the two-prong Strickland v. Washington test to determine if counsel was ineffective.

2. Improper Admission or Exclusion of Evidence

Trial judges are responsible for deciding which evidence the jury may consider. If the court improperly admitted damaging evidence—such as hearsay, illegally obtained material, or prejudicial statements—the appellate court may find that the jury was unfairly influenced. Conversely, if the court excluded important defense evidence, such as an alibi witness or exculpatory records, that decision may also be challenged.

3. Prosecutorial Misconduct

Prosecutors must follow ethical and legal standards in presenting the case. If a prosecutor made inflammatory statements during closing arguments, withheld exculpatory evidence, or knowingly presented false testimony, these actions can undermine the fairness of the criminal defense trial. Prosecutorial misconduct is a serious violation and often strengthens a criminal defense appeal.

4. Jury Instructions Errors

Jurors must be correctly instructed on the law before deliberating. If the judge provides inaccurate instructions or fails to explain an essential legal concept, the jury may misunderstand the burden of proof or the elements of the offense. Incorrect jury instructions are one of the leading causes of reversals in Ohio criminal appeals.

5. Insufficient Evidence

A conviction must be supported by sufficient evidence to prove each element of the offense beyond a reasonable doubt. If no rational jury could have reached a guilty verdict based on the evidence presented, a criminal defense attorney may argue that the conviction should be overturned. This is different from simply disagreeing with the jury's decision.

6. Sentencing Errors

Judges in Ohio must follow specific sentencing guidelines and procedures. If the court imposes a sentence outside the statutory range, fails to consider mitigating factors, or provides no explanation for its decision, the sentence may be appealed. In some cases, a sentencing error could result in a new hearing or a reduced penalty.

7. Juror Misconduct

Jurors must follow court instructions and base their verdict only on evidence presented at trial. If a juror conducts independent research, discusses the case outside court, or demonstrates bias, this behavior may compromise the integrity of the verdict. Courts may consider juror misconduct as a basis to vacate a conviction.

Common Signs That a Trial May Have Been Unfair

Not every mistake during a trial justifies a successful criminal defense appeal. However, individuals may want to speak with a criminal defense attorney if any of the following occurred during their case:

  • Key defense witnesses were not called.

  • Objections were ignored or improperly overruled.

  • The judge showed favoritism or hostility.

  • Evidence was admitted that seemed irrelevant or prejudicial.

  • The defense attorney seemed unprepared or unfamiliar with the facts.

  • The verdict contradicted the weight of the evidence.

  • There were inconsistencies in the prosecution’s case.

While no trial is perfect, significant irregularities—especially those affecting fundamental rights—can serve as a basis for appeal under Ohio law.

Timing and Procedure for Filing a Criminal Appeal

In Ohio, the defendant typically has 30 days from the date of sentencing to file a notice of appeal. This deadline is strict. Missing it without a valid reason could prevent the court from hearing the case. Once the criminal defense notice is filed, the appeals process begins.

The process generally includes:

  • Filing a transcript of the trial proceedings.

  • Submitting written briefs outlining legal arguments.

  • Oral arguments before the appellate court (if granted).

  • A written decision issued by the appellate court.

If the first appeal is unsuccessful, additional relief may be sought through post-conviction petitions or by appealing to the Ohio Supreme Court. However, each level imposes higher standards and narrower review.

How a Criminal Appeal Differs from Other Post-Conviction Remedies

Appeals are distinct from other forms of post-conviction relief. An appeal focuses solely on errors found in the trial record. By contrast, post-conviction petitions may raise new claims based on evidence not available during the trial, such as DNA results or witness recantations.

Both forms of relief are valuable tools in criminal defense, but each requires different procedures and timelines. Understanding the distinction is vital when considering legal options after a conviction.

Key Grounds That Strengthen a Criminal Appeal in Ohio

To summarize, here are the most persuasive grounds that often lead to successful criminal appeals:

  1. Ineffective assistance of counsel

  2. Admission of improper or prejudicial evidence

  3. Prosecutorial misconduct

  4. Incorrect or incomplete jury instructions

  5. Insufficient evidence to support conviction

  6. Sentencing outside statutory guidelines

  7. Juror misconduct or bias

Each of these issues points to a violation of legal rights that could have influenced the verdict or sentence. When properly identified and argued, these grounds can lead to a new trial, a modified sentence, or a full acquittal.
