Okla. Stat. tit. 82, § 82-508: Appeal from organization of district - Collateral attack

The Conservation Commission or any landowner affected by any

proposed conservancy district or by the creation of any conservancy

districts under the provisions of this act, who is aggrieved by any

order refusing to establish or establishing such district may,

within one hundred eighty (180) days after the rendition of such

order, appeal from the same to the Supreme Court of the State of

Oklahoma upon giving bond in the sum to be fixed by the court.

Provided, however, that where any order is made organizing any such

district, such judgment shall not be superseded pending appeal

unless fifty-one percent (51%) of the landowners affected by such

order join in the appeal. The organization of any conservancy

district hereunder shall not be subject to collateral attack in any

suit, action or proceeding except as to jurisdictional questions.
