In brief

Prohibited and unacceptable-use screening gate is a process, owned by the AI governance lead and carried out for each AI system. 7 recorded duties in 2 jurisdictions rely on it, and it satisfies 6 of them outright. It produces 2 kinds of evidence an auditor can ask for.

How is it implemented?

The governance lead maintains a screening list that combines the practices prohibited in each jurisdiction the organisation operates in with the uses its own policy excludes. Intake, design review and vendor onboarding each include the screen, and every existing system in the register is screened once and re-screened when its purpose, users or jurisdictions change. Borderline cases go to legal and the governance forum, and the outcome, reasoning and any conditions are recorded against the register entry. The list is reviewed whenever the law or official guidance changes.

Which legal duties does it serve?

Satisfies means the control, operated properly, does the work the duty asks for. Supports means it contributes but the duty needs more. The official text decides; open it before relying on either.

European Union 2 duties

Texas (United States) 5 duties

Which risks does it address?

Subdomains of the MIT AI Risk Repository, with the incidents the AI Incident Database has recorded under each. Counts are live; they say how often a risk has materialised, not how well this control prevents it.

Which standards clauses does it correspond to?

Clause numbers only. A reference means the standard asks for overlapping work, so evidence may be reusable; it never means the standard discharges a legal duty.
