Cal. Bus. & Prof. Code § 26230.2

The bylaws or a marketing contract may fix, as liquidated damages, specific sums to be paid by the member or stockholder to the association upon the breach by him or her of any provision of the marketing contract regarding the sale or delivery or withholding of a cannabis product and may provide that the member will pay all costs, premiums for bonds, expenses, and fees, if any action is brought upon the contract by the association. These provisions are valid and enforceable in the courts of this state. The clauses that provide for liquidated damages are enforceable as such and shall not be regarded as penalties.
