Glossary anchor
Contestability
Connect the explainer to the canonical definition for citations and shared language.
Contestability is the ability for affected people to challenge and reverse automated decisions. It requires notice, a clear appeal path, and binding authority to change outcomes.
Contestability turns accountability into a workflow with receipts, timelines, and documented remedies.
An eligibility denial includes an appeal button that guarantees a human review within 72 hours and provides a receipt for every step.

Distinct implementation signals
Unique operational detail to help this concept stand on its own in policy, procurement, and review workflows.

Evidence to ship
Report reversal rate by decision type, median time-to-remedy, and percentage of appeals receiving complete receipts.

STD-02 — Contestability & Recourse
Use the standard’s five obligations to design contestability flows.
Binding
Binding vectors
