The bill would add a new section to chapter 29A.12 RCW requiring that any contract with a vendor of ballot tabulation machines, ballot tabulation hardware, or ballot tabulation software include a provision that the vendor provide the county auditor with the source code for the program used in the tabulation device. It defines "source code" as a computer program in its original programming language written as functions, descriptions, definitions, calls, methods, and other operational statements that describe sequences of specific actions a computer interprets and executes to perform a specific task. To the extent the source code is not confidential and its disclosure is not prohibited under the referenced statutory confidentiality provisions (this title and chapter 42.56 RCW), the county auditor must make the source code available for public inspection and copying. The bill also contains legislative findings stating that public transparency in election tabulation source code will increase voter confidence and that manufacturers currently do not share source code with the public. This is a procedural change creating a new statutory requirement for contracts and conditional public-disclosure duties for county auditors; it does not create a new crime or change penalties in the extracted text. The provided material does not specify an effective date, whether the requirement applies to existing contracts or only new contracts, the procedures for providing or redacting confidential portions, enforcement mechanisms, or which specific provisions of "this title" control confidentiality.

If enacted, counties will have to require election tabulation vendors to hand over the tabulation programs’ source code and, except for parts already protected by law, make that code available for public inspection and copying. That will increase county auditors’ responsibilities: they will need to receive and store source code, review what parts are legally confidential, respond to public inspection and copying requests, and likely seek legal or technical help to decide what can be released, which could raise their workload and costs. Vendors and manufacturers will face a new contract requirement whenever counties buy tabulation machines, hardware, or software, which may affect how they negotiate contracts or what they are willing to supply to counties. Important details are missing from the text provided — for example whether the rule applies to existing contracts, how auditors must provide access, and what enforcement or penalties apply — so those open items could materially change how burdens and costs actually play out.
