Advisory Committee Comment

The Judicial Council has adopted an optional form, Certificate of Interested Entities or Persons (form APP-008), that can be used to file the certificate required by this provision.

Subdivision (a). Under rule 8.208(c), for purposes of certificates of interested entities or persons, an "entity" means a corporation, a partnership, a firm, or any other association, but does not include a governmental entity or its agencies or a natural person.
