How a DUI Conviction Appeal Works
After a conviction, some people want a higher court to review the case. A DUI conviction appeal asks that court to look for legal errors. It is not a new trial.
The court that hears the appeal depends on the case level. So a misdemeanor and a felony follow different paths.
Misdemeanor Appeals
Penal Code section 1466 allows appeals in misdemeanor and infraction cases to the appellate division of the superior court in the same county. The section lists which judgments and orders each side may appeal. Most misdemeanor DUI appeals go there.
Felony appeals go to the Court of Appeal instead. Deadlines for filing a notice of appeal are short, so ask a lawyer right away.
What an Appeal Reviews
An appeal looks at the record from the trial court. For example, it may review rulings on evidence, motions and jury instructions. New evidence usually does not come in on appeal.
Therefore, objections made during trial often matter. A lawyer can explain which issues the trial record preserved.
DUI Conviction Appeal Compared With Other Relief
Record relief is different from an appeal. Penal Code section 1203.4 allows dismissal after probation in many cases, but it does not erase the conviction for all purposes. The section also lets the prosecution plead and prove the prior conviction in a later case.
Also, Vehicle Code section 13555 says that relief does not affect DMV suspensions or revocations. The article on California DUI expungement explains more.
The DMV Track
DMV decisions follow their own review path. The guide on DMV DUI hearing appeal options explains that process. So a court appeal and a DMV review may run at the same time.
Questions for a Lawyer
Ask what issues could support a DUI conviction appeal. Also ask about the deadline and the cost of transcripts. Then ask whether the sentence continues during the appeal.
The article on DUI jury trial steps explains how the court builds the trial record.
Appeals can take months. So plan for the sentence terms to continue unless a court orders otherwise.
A DUI conviction appeal also has costs. For instance, transcripts and filing fees may apply, and some people qualify for waivers. So ask about fees early, since delays can affect deadlines.
Some issues fit other forms of review better than an appeal. For example, claims based on facts outside the record may need a different petition. A lawyer can explain which path fits.
