Part 7: Bulk personal dataset warrants Section 220: Initial examinations: time limits
This section explains the process of, and sets time limits for, the initial examination of a bulk personal dataset. Subsection (1) states that this section applies when an intelligence service obtains a bulk personal dataset, i.e. a set of information it believes includes or may include personal data relating to a number of individuals, the majority of whom are not, or unlikely to become of interest to the service in the exercise of its functions.
	Subsection (2) outlines the steps that the intelligence service must take, and requires these steps to be taken with a set period. These steps are: an initial examination to determine whether it is a bulk personal dataset; reaching a decision whether to retain the dataset; and making an application for a specific BPD warrant (unless the dataset is authorised by a class BPD warrant).
	Subsections (3) and (4) define the beginning and end of the set period during which the steps must be taken. The period begins when the intelligence service first forms the belief outlined in subsection (1). The period ends after three months where the set of information was created in the UK or after six months where the set of information was created outside the UK. Subsection (5) makes clear that it remains lawful for an intelligence service to retain a bulk personal dataset for the period between deciding to apply for a specific BPD warrant and the determination of that application, and that it is lawful for the intelligence service to examine the bulk personal dataset during that period if the examination is necessary for the purpose of applying for the warrant.
