It described signature collection and verification as subsequent steps. This is **not certification of voter approval** and does not satisfy W293’s resolution criteria. [Official announcement](https://www.ohioattorneygeneral.gov/Media/News-Releases/March-2026/Title-and-Summary-Certified-for-Proposed-Prohibiti)\n\n- **California:** The Secretary of State’s **February 5, 2026 announcement** authorized signature collection for initiative **25-0034A1**. Its official summary describes an AI Safety Commission, safety-plan requirements, advance notification of capability expansion, and discretionary authority to limit expansion. **That announcement does not establish an express development moratorium or certified voter approval.** [Official announcement](https://www.sos.ca.gov/administration/news-releases-and-advisories/2026-news-releases-and-advisories/proposed-initiative-enters-circulation-regulates-certain-large-artificial-intelligence-ai-companies-initiative-statute)\n\nBoth publications also predate the question’s **September 16, 2026 opening date**. Neither is a qualifying resolution document.\n\nA factual resolution assessment would require the competent electoral authority’s **published certification of passage**, dated within the applicable window, together with the **official adopted text** establishing a qualifying statewide or nationwide prohibition. The proposal documents above are not sufficient to determine whether the question has resolved."
