Yes, you can appeal a conviction if you believe there has been a legal error, however an appeal does not constitute a retrial, but it is a request for a higher court to review your case to evaluate whether there were legal errors made, leading to a wrongful conviction. The grounds for appeal include: 

• Legal error: a mistake made by the judge during a trial that significantly impact the outcome of that trial.

• Exclusion or improper admission of evidence.

• Ineffective assistance of counsel: if the defendant’s lawyer made serious errors or misrepresented the defendant.

• Jury misconduct: if the jury behaved in an inappropriate manner.

• Prosecution misconduct: the prosecution behaved in an unethical manner, such as withholding evidence.

• Insufficient evidence: the evidence presented was not enough to prove the defendant was guilty beyond a reasonable doubt.
