Okla. Stat. tit. 57 § 582.5

In OCCA case No. S-2013-413 & 415, Mark Anthony Herfurth appealed his conviction for Failure to Register as a Sex Offender and Sex Offender Living within 2000 feet of a School. In an unpublished decision, the court decided to affirm the lower court's ruling to dismiss the charges against him. One judge dissented. Mark Anthony Herfurth was taken to court because he was accused of not registering as a sex offender and for living too close to a school after he had been convicted of a crime related to indecent exposure. In his earlier conviction, he had agreed to register as a sex offender for a certain number of years. However, when laws changed in 2007, it meant that people in his situation could be assigned a risk level and have to register for longer. Herfurth argued that he shouldn't be held to the new law because he had already completed his requirements from his original plea. The judge agreed with him and dismissed the charges, saying that the laws could not be applied to him retroactively. The State of Oklahoma did not agree with this decision. They believed that the new law should apply to Herfurth since he was still required to register as a sex offender. They argued that laws are meant to protect the public, and because he was registering at the time of the new law's change, he should follow the new rules. However, upon review, the court decided that the lower court did not make a mistake. They concluded that the 2007 law was a significant change and should only apply going forward, not backward. The court also stated that applying the 2007 law to Herfurth after his original plea would have changed his obligations unfairly. Therefore, the appeals court agreed with the lower court's decision to dismiss the charges against Herfurth, stating that they have a duty to interpret laws as they were intended at the time of the original guilty plea. The dissenting judge felt differently, believing that the law should have applied to Herfurth based on the new requirements.
