If you were just convicted of a crime there is a process that may be able to help. It is called the criminal appeals process and is handled by a criminal Appellate court lawyer. A criminal appeals lawyer is admitted to the appellate court and will act on your behalf to prove there was an error in the trial process that allows you to request an appeal of your criminal verdict.
When you hired your lawyer and went to court, you hoped for the best, but if the judge made errors or the lawyer dropped the ball on your case and you lost you have a real chance to challenge the judgment or sentence. An appeal looks at what the Judge or the other side did or did not do and another Court examines what happened at trial and look to see if there was enough error to grant a new trial.
