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.

What do other lawyers say?

 "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

John Dunn's Recent Victories


When a client was arrested for Actual Physical Control while sitting in the passenger seat of a running motor vehicle.  The law at the time permitted the revocation of the client's driver's license.  While the criminal charge was dismissed, the Department of public Safety continued to pursue the client's driver's license.  The Department was successful at both the administrative court and the district court level.  However, John Dunn's firm successfully appealed a District Court's decision to take away his client's driver's license.  John Dunn and associate Stephanie Bush successfully convinced the Court of Civil Appeals that the crime of "Actual Physical Control" requires some intent to drive.


In Tulsa County, the district court dismissed a case before District Court Arraignment, finding that the witness that provided the evidence necessary for the examining magistrate was not credible.  The State appealed, arguing that credibility is an issue for the jury.  The attorney for the defendant asked for help.  John Dunn and MJ Denman successfully convinced the Oklahoma Court of Criminal Appeals that the State is required to establish the reliability of the evidence it offers at preliminary hearing in order to bind the Defendant over to district court.


John Dunn made law by successfully arguing that the Oklahoma Sex Offender Registration was so punitive that it could not be applied retroactively without violating the ex post facto clause of the Oklahoma constitution.  This opinion makes Oklahoma one of the few states that has found their law to be punitive. Since this opinion was released, it has been cited by other courts of the United States as a basis for limiting the unconstitutional application of these kinds of punitive statutes nationwide. Mr. Dunn has additionally prepared a "question and answer" page about this opinion and some subsequent decisions expanding on the Supreme Court's decision.


John Dunn successfully represented a client that had been defaulted by the District Court for failure to timely answer a Petition.  John Dunn successfully argued that his client had not received the notice required by law and that as a result, they were entitled to be heard.  Mr. Dunn will now get the opportunity to represent his client in litigation that they were previously denied.


John Dunn championed the cause of a single mother who had changed her mind about giving her child up for adoption.  The prospective adoptive parents pursued a guardianship in an effort to keep custody of the child - despite the fact that they were not qualified to be guardians under Oklahoma Law.  John Dunn and his associate Brian Melton rode to the rescue and took the matter to the Oklahoma Supreme Court.  The Court ordered that the out of state guardians be removed and awarded Natural mother her attorney fees.

In an order that keeping in line with Starkey, John Dunn recently successfully argued to the District Court of Tulsa County that the residency restrictions do not apply to a person who became subject to the act prior to 203 when that portion of the law was enactedThe Order has also been included here so it can be downloaded.  (During argument, the City of Tulsa offered an interesting internal memo from where it is represented that police policy prohibits arrest on sight if someone is residing in a "zone of safety".)
