If a cooperative has filed defective articles of incorporation, or has failed to do all things necessary to perfect its corporate organization, it may file corrected articles of incorporation, or amend the original articles, and do and perform all acts and things necessary for the correction of the defects. The action so taken is valid and binding upon all persons concerned. The capacity of the cooperative to file corrected articles of incorporation or amendments to the original articles, or to do and perform all acts and things necessary, may not be questioned.
