John Dunn


Some have described me as “unwavering” when it comes to principles. Others say that I exhibit the trait of "loyalty to a fault" or that I am "utterly relentless” when pursuing an objective. As your attorney, I promise to be a loyal advocate and to be unwavering in the pursuit of your goals. I am a zealous advocate that does not shy away from conflict and litigation. I believe that the strongest weapon that an attorney can have is knowledge of his case. I will aggressively prepare your case for litigation while attempting to resolve the issues on favorable terms - a kind of "peace through strength" approach to the practice of law.

 "In this day of large law firms and multi-million dollar budgets for state and federal governments, don't ever forget that ONE dedicated and talented criminal defense lawyer took on the entire state of Oklahoma Department of Corrections, Attorney General's Office and beat the hell out of them.  Who says the days of the solo practitioner and Lone Wolf are gone?  Not me."  

 - Jack Dempsey Pointer     Former President of the Oklahoma Criminal Defense Lawyers Association

An appeal is a legal proceeding that happens after a final judgment is made in the District Court.  It is available to  either party - the losing party may appeal in an attempt to overturn the trial court's decision and the prevailing party may appeal in an attempt to gain more relief than the court awarded.  Appellate practice is notably different than trial practice.  In many instances, it is a good idea to retain new counsel to handle the appeal, as the first step of an appeal is a critical review of the existing record.


Appeals are limited to the record as it exists.  Generally, speaking, neither party is permitted to introduce new evidence into the record that was not considered during the trial.  The reason for this rule flows directly from the dual role of the trial court - to determine the facts by evaluating the credibility of the evidence and apply those facts to the law.  The appellate court gives deference to the trial court as far as factual issues are concerned, but reserves the application of law to itself.


Therefore, representation in this area begins with the timely filing of a filing of a petition in error.  The appellate attorney then conducts a thorough review of the record - which requires the review of all transcripts, depositions and all evidence that have been introduced at the trial court.  A brief is prepared and submitted to the appellate court.  All issues to be considered must be raised in this brief or they are waived.  The appellate court then considers the briefs of all parties and determines if oral argument is required.  If so, oral argument is scheduled before the appellate court.  The appellate court then enters its decision. 


Before hiring an attorney, it is important to know if the attorney has had any success in the area.  John Dunn has recently been awarded the 2013 OCDLA Thurgood Marshall Award for his outstanding appellate advocacy!
