A person who knowingly sells or offers for sale or trade livestock without the person's recorded brand, or for which the person has neither a bill of sale, as provided by section 3-1291, nor power of attorney from the owner authorizing the sale, is guilty of a class 5 felony, unless the person proves that at that time the person was the owner, acted by direction of the owner or acted in good faith.
