There is a common misconception that you need people's consent before you can do anything with their data - as you will see from the list below consent is just one of conditions that you may be able to rely on.
Section 7 of the Law sets out the requirements for processing to be lawful. It refers to Schedule 2 of the Law and the conditions for processing within that Schedule.
Do not start processing any personal data unless you have clearly established and documented details of the relevant condition/s.
The majority of conditions require that ‘the processing is necessary’ in order to be able to rely upon them. This means that if you could reasonably achieve the same purpose without the processing you cannot rely upon that condition.
There is a separate set of conditions for when you are processing special category data (i.e. racial or ethnic origin; political opinion; religious or philosophical belief; trade union membership; genetic data; biometric data; health data; sex life; criminal data)
For personal data not considered to be special category data, you must satisfy at least one of the conditions below:
