The Guide to Law Enforcement Processing is part of our Canllaw i Ddiogelu Data . It is for those who have day-to-day responsibility for data protection in organisations with law enforcement functions.

It explains the data protection regime that applies to those authorities when processing personal data for law enforcement purposes. It covers part 3 of the Data Protection Act 2018 (DPA 2018), which implements an EU Directive (Directive 2016/680) and is separate from the GDPR regime.

It explains each of the data protection principles, rights and obligations. It summarises the key points you need to know and answers frequently asked questions.

Where relevant, this guide also links to more detailed guidance and other resources, including ICO guidance and European guidance published by the European Data Protection Board (EDPB).

This section only covers processing for law enforcement purposes. You will need to read our Guide to the GDPR when processing for non-law enforcement purposes.
