The Logic Explained

Where the organisation makes solely automated decisions about the person, the response gives meaningful information about the logic involved.

Criterion: E9
Level: Level 1
Domain: Supplementary Information
Reflects: Article 15(1)(h)

Intent

The logic is what lets a person contest a decision rather than simply receive it. It calls for what the system weighed, not the source code.

How to test it

An assessor scores the criterion against a single response:

Score 2: The response describes what the system takes into account and how those things bear on the outcome, in terms the person can follow.
Score 1: The response names the factors used without saying how they bear on the outcome, or describes the process only in general terms.
Score 0: The response says the logic is confidential, refers to an algorithm without explaining it, or says nothing.
Not applicable: The organisation makes no solely automated decisions about the person.

The law it reflects

This criterion reflects Article 15(1)(h) of the UK GDPR. That mapping is a guide, not a legal test: conformance is judged against the criterion, not the article.
