# Who Holds Legal Liability for Third-Party Agent Hallucinations?

**Open question.** While the article argues consumers *perceive* platform hallucinations as brand failures ([[claim-brand-failure-not-system-error]]), it leaves open the question of **legal and financial liability**. If a general-purpose AI (like [[entity-chatgpt-d14]]) promises a customer a **non-existent discount** on a brand's product, is the **brand legally obligated to honor it**, or is the **AI platform** liable?

**Resolution path.** Future **regulatory rulings** or **high-profile lawsuits** establishing precedent for AI-agent intermediary liability.

> **Enrichment / counter-perspective.** Legal scholars and regulators are actively debating whether platforms, brands, or intermediaries bear liability for AI-generated misrepresentations. Some argue that **platforms providing the AI should carry primary responsibility**, especially where brands have limited control over how they are described — which directly challenges the article's assumption that misrepresentation is always *treated* as a brand failure. Relevant governance context: OECD AI Principles, the EU AI Act, and the NIST AI Risk Management Framework.
