- Why the court cared
- Fabricated: Case Law | Several cited cases did not exist; provided links directed the court to a large language model platform webpage indicating the citations were fabricated by AI. || Misrepresented: Case Law | Other cited authorities were real but were relied on for propositions they did not support (irrelevant or misrepresented precedent).
- Why it matters now
- Pro-se AI hallucinations in Alberta appellate filings drew warnings, not sanctions — threshold remains attorney conduct.
