Status

The term provision is used to describe a definable element in a piece of legislation that has legislative effect – such as a Part, Chapter or section. A version of a provision is prospective either:

  1. where the provision (Part, Chapter or section) has never come into force or;
  2. where the text of the provision is subject to change, but no date has yet been appointed by the appropriate person or body for those changes to come into force.

Commencement Orders listed in the ‘Changes to Legislation’ box as not yet applied may bring this prospective version into force.

(b)how the processing satisfies section 35 (lawfulness of processing), and

(c)whether the personal data is retained and erased in accordance with the policies described in subsection (2)(b) and, if it is not, the reasons for not following those policies.

(5)In this section, “relevant period”, in relation to sensitive processing in reliance on the consent of the data subject or in reliance on a condition specified in Schedule 8, means a period which—

(a)begins when the controller starts to carry out the sensitive processing in reliance on the data subject's consent or (as the case may be) in reliance on that condition, and
