Overview
- Governor Ned Lamont signed Senate Bill 5, the Connecticut Artificial Intelligence Responsibility and Transparency Act, into law on May 27, 2026.
- The statute creates a broad definition of “automated employment-related decision technology” (AEDT) to cover systems whose outputs are a substantial factor in hiring, promotion, performance, pay, or layoff decisions and excludes routine administrative tools like word processing and data storage.
- Starting October 1, 2027, employers using AEDT that interacts with applicants or employees must give plain-language interaction notices and, when AEDT substantially influences a decision, written disclosures naming the tool, its purpose, data categories and sources, and employer contact information.
- The law bars an employer’s reliance on AEDT as a defense in discrimination claims beginning October 1, 2026 while allowing courts or the state human-rights commission to consider documented anti-bias testing and mitigation efforts as evidence of care.
- AEDT developers must supply employers with the information needed for compliance and may be contractually assigned notice duties, and the Connecticut attorney general — not private plaintiffs — enforces the law with a temporary notice-and-cure regime for early violations.
