AI coding agents are transforming how organizations build software, but they do not change the legal or organizational accountability attached to software development, because current law treats AI systems as tools without independent legal agency. Under the EU AI Act (Regulation (EU) 2024/1689), AI systems are explicitly defined as technologies used by “providers” and “deployers,” meaning that the deploying organization — not the AI tool — is responsible for compliance. This principle is also consistent with longstanding U.S. tort doctrine, where liability is assigned to human actors and organizations rather than automated systems.

Because of this, responsibility for AI-generated code remains with the organization and the individuals acting within their professional responsibilities, not the AI agent. This legal structure means that AI tools must be supervised by qualified personnel and embedded into existing review and validation processes. The EU AI Act further reinforces this by requiring “appropriate human oversight” in systems that may materially affect individuals, which includes AI systems capable of generating software or modifying product behavior.

Human validation therefore remains mandatory. AI output is probabilistic and can contain errors, security vulnerabilities, or biased patterns, making human review necessary under both engineering best practices and regulatory expectations. GDPR (European Commission, 2022) also requires data controllers and processors to ensure security and data-protection-by-design, which applies when AI-generated code interacts with personal data or system logic.

The responsibility of defining requirements, evaluating outputs, and determining whether code is acceptable for integration remains entirely human. This position is reinforced by case law such as Mobley v. Workday (N.D. Cal. 2024), where the court evaluated an AI-assisted decision-making system under existing anti-discrimination law rather than treating the AI as an autonomous actor. Here, the AI system’s decisions were legally attributed to the deploying organization — illustrating the consistent principle that AI cannot “own” the consequences of its outputs.
