California Code, Government Code - GOV § 17558.7

(a) If the Controller reduces a claim approved by the commission, the claimant may file with the commission an incorrect reduction claim pursuant to regulations adopted by the commission.

(b) A claimant eligible to file an incorrect reduction claim may file a consolidated incorrect reduction claim on behalf of other claimants whose claims for reimbursement under the same mandate are alleged to have been incorrectly reduced if all of the following apply:

(c) A claimant that seeks to file a consolidated incorrect reduction claim shall, at the time it files an incorrect reduction claim, on a form provided by the commission, notify the commission of its intent to file a consolidated incorrect reduction claim.

(d) Within 10 days after receipt of an incorrect reduction claim and notice of intent to consolidate, the commission shall request that the Controller provide the commission and the claimant with a list of claimants for whom the Controller has reduced similar claims under the same mandate. Upon receipt of this list from the Controller, the claimant may notify the claimants on the list and other interested parties of its intent to file a consolidated incorrect reduction claim.

(e) Within 30 days of receipt of the notice of intent to consolidate from the original claimant, on a form provided by the commission, any other eligible claimant shall file with the commission its notice of intent to join the consolidated incorrect reduction claim, which shall include a copy of the remittance advice or other notice from the Controller of the claim reduction, and one copy of the reimbursement claims for which an incorrect reduction is alleged.

(f) The commission shall notify each claimant that files an intent to join the consolidated incorrect reduction claim that it may opt out of the consolidated claim and not be bound by any determination made on that consolidated claim. A claimant may opt out of a consolidated claim no later than 15 days after the state agency files comments on the consolidated claim. A claimant that opts out of the consolidated claim, in order to preserve its right to challenge a reduction made by the Controller on that same mandate, shall file an individual incorrect reduction claim pursuant to commission requirements, no later than one year after opting out or within the statute of limitations under the commission's regulations.

(g) The commission shall adopt regulations establishing procedures for receiving a consolidated incorrect reduction claim pursuant to this section and for providing a hearing on a consolidated claim.
