What evidence should a data holder keep for a Data Act B2G exceptional-need request?
The Data Act context is the starting point for this answer. Keep enough evidence to show whether the request was valid, how the company responded, what data was made available or withheld, and which safeguards governed the data after transfer. The evidence file should be built around the Article 17 request contents and the Article 18 response, not around generic compliance notes.
A useful record includes the written request, requester identity, statutory task and legal provision, exceptional-need route, public-emergency declaration or non-emergency exhaustion analysis, data scope and metadata, personal-data analysis, trade-secret identification, timestamps, refusal or modification reasons, compensation calculation, delivery logs, onward-sharing notices, erasure notice, and competent-authority communications.
- For emergency requests, keep the public-emergency basis, alternative-means analysis, five-working-day response record, and any public-acknowledgement request.
- For non-emergency requests, keep the non-personal-data classification, exhausted-means evidence, market-purchase record where relevant, 30-working-day response record, and compensation basis.
- For safeguards, keep anonymisation or pseudonymisation decisions, security measures, trade-secret protections, purpose limitation, onward-sharing notifications, and deletion confirmations.
Articles 17 through 21 define the request fields, response windows, safeguards, compensation records, onward-sharing notices, and erasure obligations that drive the evidence file.
