Code of Civil Procedure Article 44-2

(1) When multiple parties, whose common interests have arisen from the same public nuisance, traffic accident, product defect, or the same transaction or occurrence of any kind, appoint one or more persons from themselves in accordance with the provision of Article 41 to sue for the same category of legal claims, the court may, with the consent of the appointed party, or upon the original appointed party's motion which the court considers appropriate, publish a notice to the effect that other persons with the same common interests may join the action by filing a pleading within a designated period of time specifying: the transaction or occurrence giving rise to such claim; the evidence; and the demand for judgment for the relief sought. Those persons so joining shall be deemed to have made the same appointment in accordance with the provisions of Article 41.(2) Other persons with the same common interest may also move the court to publish the notice provided in the preceding paragraph.(3) A written copy or photocopy of the pleading of joinder shall be served upon all parties to the action.(4) The publication period of the notice provided for in the first paragraph shall be no less than twenty days. The same notice shall be posted on the court's bulletin board and the court's website. Where the court considers it necessary, the notice may be published in official gazettes, newspapers, or other similar means of communication. The expenses for such publication shall be advanced by the national treasury.(5) When the appointed party provided in the first paragraph does not agree to such joinder, the court may, on its own initiative, publish a notice to inform other persons with the same common interests to initiate actions and then the court will consolidate the actions.
