Okla. Stat. tit. 11, § 11-39-108: Hearings on creation of district - Protests and

objections.

A. At the hearing of the governing body on the proposed

resolution creating a district, any interested person or owner of

property to be assessed for the improvement may file a written

protest or objection questioning the:

1. Propriety and advisability of constructing the improvement;

2. Estimated cost of the improvement;

3. Manner of paying for the improvement; and

4. Amount to be assessed against the individual tract or parcel

of land.

B. The governing body may recess the hearing from time to time

so that all protestants may be heard.

C. At the hearing, the governing body may:

1. Correct any mistake or irregularity in any proceeding

relating to the improvement;

2. Correct an assessment made against any tract or parcel of

land;

3. In case of any invalidity, reassess the cost of the

improvement against an abutting tract or parcel of land;

4. Delete any tract or parcel of land, protested by the owner,

from the district; and

5. Recess the hearing from time to time.

D. Within thirty (30) days after the governing body has

concluded the hearing; determined the advisability of constructing

the improvement and the type and character of the improvement; and

created the improvement district, any person who, during the

hearing, filed a written protest with the governing body protesting

the construction of the improvement may commence an action in

district court to correct or set aside the determination of the

governing body. After the lapse of thirty (30) days succeeding the

determination of the governing body, any action attacking the

validity of the proceedings and the amount of benefit to be derived

from the improvement is perpetually barred. Provided, however, if

the owners of fifty percent (50%) or more in area of the tracts or

parcels within the district or a majority of the owners of record of

property in the assessment area protest, in writing, the creation of

the district, the district shall not be created.
