On what grounds can a criminal conviction be appealed?

On Behalf of | Sep 25, 2014 | Criminal Appeals |

If you as a defendant lose a criminal case at trial, then your opportunities for a successful appeal become limited and time-sensitive. It is important, then, to have an attorney on your side with experience in the appellate process. Making a successful appeal involves scouring the trial record for mistakes that resulted in your conviction.

Here let’s go over three common grounds for appeals: prosecutorial or police misconduct, inadequate counsel and discovery of new evidence.

Misconduct on the part of the police or the prosecution may include the following:
  • The intentional omission of evidence that might have resulted in exoneration
  • Allowing false testimony to be admitted at trial
  • Other miscarriages of justice committed by police before, during or after the arrest

Note: an appeal based on prosecutorial misconduct may still be successful even if the prosecution unknowingly or unintentionally committed misconduct.

To win an appeal based on a claim of inadequate or ineffective counsel, the following two things must be shown in conjunction:

  • The defendant’s former attorney, whether at the original trial or an appellate trial, performed inadequately.
  • The lawyer’s inadequate performance affected the outcome of the trial.

When new evidence is the basis of a successful appeal, the evidence typically falls into one or more of these categories:

  • Newly discovered
  • Not available at the original trial
  • Overlooked a the original trial

Note: new evidence, even DNA tests, must be properly developed and presented to win an appeal. This often leads to the dismissal of the case and the freeing of the defendant.
