HB 1121 clarifies Oklahoma's public nuisance law to protect businesses selling lawful products from being labeled as public nuisances. It requires courts to find a defendant "in control of the conditions" causing a nuisance before liability, and strengthens requirements for private lawsuits by mandating "clear and convincing evidence" that the nuisance caused specific harm. These changes directly affect businesses facing nuisance claims and individuals seeking to sue for private injuries. The bill takes effect November 1, 2025.
