D.C. Court Strikes AI-Cited Deutsche Bank Brief
Concrete judicial ruling on AI citation failure sets a precedent APS legal and policy teams should factor into AI-assisted drafting controls.
Key points
- A D.C. appellate court struck a Deutsche Bank brief after four AI-generated citations were confirmed nonexistent.
- The attorney used Google's generative-AI search tool without verifying citations - the court referred the matter for discipline.
- The ruling reinforces that verification controls, not just AI use policies, are required in high-consequence workflows.
Implications for Australian agencies
- Consider APS legal, policy, and governance teams using generative AI in drafting may want to consider whether their workflows include mandatory citation verification against authoritative repositories before sign-off.
- Monitor Agencies developing or updating AI use policies for professional staff may want to monitor how courts and disciplinary bodies in Australia and peer jurisdictions respond to similar AI citation failures.

On 3 September 2026, the D.C. Court of Appeals struck an appellate brief in a mortgage-foreclosure case after determining that four legal authorities cited by attorney Loishirl Hall did not exist. Hall acknowledged using Google's generative-AI search tool without verifying the citations before filing. The panel characterised the conduct as negligent or grossly negligent and referred the matter to the D.C. disciplinary system. The order stopped short of banning AI use, emphasising instead that lawyers remain responsible for verifying all cited authorities. The case is a concrete illustration of why source-resolution controls - not just tool policies - are necessary in high-stakes drafting workflows.
Implications for Australian agencies:
- [Consider] APS legal, policy, and governance teams using generative AI in drafting may want to consider whether their workflows include mandatory citation verification against authoritative repositories before sign-off.
- [Monitor] Agencies developing or updating AI use policies for professional staff may want to monitor how courts and disciplinary bodies in Australia and peer jurisdictions respond to similar AI citation failures.
