What happened
Navy Federal Credit Union is facing allegations of racial bias in its mortgage approval process. A class action lawsuit claims the credit union denied loans for 52% of Black borrowers and 44% of Latino borrowers, while denying only 23% of white applicants. The Fourth Circuit Court of Appeals recently revived these claims to allow the lawsuit to proceed.

- 04 · FailureThe output crosses the policy line.
- 05 · ConsequenceA limit the business set is breached in public.

Realm compares what the model is about to output or do against the policy that governs the deployment, in real time, and can deny or redact the action before it takes effect, which is the gap an after-the-fact review never closes in time.
