In this letter, the Alliance to End Slavery and Trafficking (ATEST) and its partners urged the California Franchise Tax Board to release information the Board had withheld as "confidential", in conflict with the relevant disclosure provisions of the California Revenue and Tax Code and the state's Public Records Act. 

The information in question was a list of corporations required to comply with the disclosure requirements of the California Transparency in Supply Chains Act (CTSCA).  As a disclosure law, the letter states, "CTSCA's explicit goal is to identify the subset of corporations doing business in California that meet certain global revenue parameters and to require them to disclose their anti-trafficking efforts in order to inform and educate the public...In the absence of access to the list of corporations meeting the threshold reporting requirements of the CTSCA, consumers will not be able to identify those corporations to whom written requests may be submitted, thereby directly contravening the mandate of the CTSCA."
