California Corporations Code > Title 3. Unincorporated Associations > Part 1. General Provisions > Chapter 6. Governance > Article 2. Termination or Suspension of Membership > Corp. Code §18320. Procedures for Expulsion or Suspension of Membership
(a) This section only applies if membership in an unincorporated association includes a property right or if expulsion or suspension of a member would affect an important, substantial economic interest. This section does not apply to an unincorporated association that has a religious purpose.
(b) Expulsion or suspension of a member shall be done in good faith and in a fair and reasonable manner. A procedure that satisfies the requirements of subdivision (c) is fair and reasonable, but a court may also determine that another procedure is fair and reasonable taking into account the full circumstances of the expulsion or suspension.
(c) A procedure for expulsion or suspension of a member that satisfies the following requirements is fair and reasonable:
(1) The procedure is included in the unincorporated association’s governing documents.
(2) The member to be expelled or suspended is given notice, including a statement of the reasons for the expulsion or suspension. The notice shall be delivered at least 15 days before the effective date of the expulsion or suspension.
(3) The member to be expelled or suspended is given an opportunity to be heard by the person or body deciding the matter, orally or in writing, not less than five days before the effective date of the expulsion or suspension.
(d) A notice pursuant to this section may be delivered by any method reasonably calculated to provide actual notice. A notice delivered by mail shall be sent by first-class, certified, or registered mail to the last address of the member shown on the unincorporated association’s records.
(e) A member may commence a proceeding to challenge the expulsion or suspension of the member, including a claim alleging defective notice, within one year after the effective date of the expulsion or suspension. The court may order any relief, including reinstatement, it determines is equitable under the circumstances. A vote of the members or of the board may not be set aside solely because a person was wrongfully excluded from voting by virtue of the challenged expulsion or suspension, unless the court determines that the wrongful expulsion or suspension was in bad faith and for the purpose, and with the effect, of wrongfully excluding the member from the vote or from the meeting at which the vote took place, so as to affect the outcome of the vote.
(f) This section governs only the procedure for expulsion or suspension and not the substantive grounds for expulsion or suspension. An expulsion or suspension based on substantive grounds that violate contractual or other rights of the member or are otherwise unlawful is not made valid by compliance with this section.
