First off, let me say that not everyone who has been convicted of a California DUI crime should plan on filing an appeal. The California appellate process is very limited and only deals with specific legal issues. This means that unless your DUI case involves one of these issues, an appeal will be fruitless. This is why having a basic understanding of how to appeal a California criminal conviction is so important.
But before you can appreciate how to appeal a California criminal conviction, you must evaluate whether you should file an appeal. Disappointment in the outcome of the case or a personal belief that California's DUI laws are too harsh are not appropriate grounds for appealing a California conviction. However, police misconduct, unethical prosecution, a biased jury, and/or incorrect legal rulings are.
So if you believe you may have been the victim of an unjust conviction, you should meet with a California appeals lawyer. He/she will review your case and explain exactly how to appeal your California criminal conviction. He/she will explain the types of rules that regulate appeals, the types of written and oral arguments he/she will present and all possible outcomes.
While it is possible for you to represent yourself during the appeals process, know that you will be held to the exact same technical and complex standards as a licensed attorney. This means that unless you master the rules that govern how to appeal a California criminal conviction, you will surely be doing yourself a disservice.
