What is the lawful basis for processing?
When collecting data it is necessary to clearly understand and communicate the lawful reason for processing to the data subject.
Why is the lawful basis for processing important?
The first data protection principle requires that you process all personal data lawfully, fairly and in a transparent manner. Processing is only lawful if you have a lawful basis under Article 6. And to comply with the accountability principle in Article 5(2), you must be able to demonstrate that a lawful basis applies.

- (c) Legal obligation: the processing is necessary for you to comply with the law (not including contractual obligations).
- (d) Vital interests: the processing is necessary to protect someone’s life.
- (e) Public task: the processing is necessary for you to perform a task in the public interest or for your official functions, and the task or function has a clear basis in law.
- (f) Legitimate interests: the processing is necessary for your legitimate interests or the legitimate interests of a third party unless there is a good reason to protect the individual’s personal data which overrides those legitimate interests. (This cannot apply if you are a public authority processing data to perform your official tasks.)
