Oregon Revised Statutes Corporations and Partnerships § 63.801

(1) A member may not commence a proceeding in the right of a domestic or foreign limited liability company unless the person was a member of the limited liability company when the transaction complained of occurred or unless the member became a member through transfer by operation of law from one who was a member at that time.

(2) Except as otherwise provided in writing in the articles of organization or any operating agreement, a complaint in a proceeding brought in the right of a limited liability company must allege with particularity the demand made, if any, to obtain action by the managers or the members who would otherwise have the authority to cause the limited liability company to sue in its own right, and either that the demand was refused or ignored or the reason why a demand was not made. Whether or not a demand for action was made, if the limited liability company commences an investigation of the charges made in the demand or complaint, the court may stay any proceeding until the investigation is completed.

(3) A proceeding commenced under this section may not be discontinued or settled without the court's approval. If the court determines that a proposed discontinuance or settlement will substantially affect the interest of the members or a class of members, the court shall direct that notice be given to the members affected.
