Consent
A Data Controller must only process Personal Data on the basis of one or more of the lawful bases set out in the GDPR, which include Consent.
A Data Subject consents to Processing of their Personal Data if they indicate agreement clearly either by a statement or positive action to the Processing. Consent requires affirmative action so silence, pre-ticked boxes or inactivity are unlikely to be sufficient. If Consent is given in a document which deals with other matters, then the Consent must be kept separate from those other matters.
Data Subjects must be easily able to withdraw Consent to Processing at any time and withdrawal must be promptly honoured. Consent may need to be refreshed if you intend to Process Personal Data for a different and incompatible purpose which was not disclosed when the Data Subject first consented.
Unless the Council can rely on another legal basis of Processing, Explicit Consent is usually required for Processing Sensitive Personal Data, for Automated Decision-Making and for cross border data transfers. Usually we will be relying on another legal basis (and not require Explicit Consent) to Process most types of Sensitive Data. Where Explicit Consent is required, you must issue a Fair Processing Notice to the Data Subject to capture Explicit Consent.
The Council will need to evidence Consent captured and keep records of all Consents so that the Council can demonstrate compliance with Consent requirements.
