IPCO Annual Report 2018
12.17
Our inspections at the most common users of CD generally noted a high standard of
compliance and we made no recommendations. In respect of the application records
we sampled, we were satisfied that the documentation reflects the complexities of their
investigations and justifies the principles of necessity, proportionality and collateral
intrusion. We were similarly satisfied that the appropriate threshold was maintained in
relation to investigating criminal activity, as distinct from internal disciplinary matters.

The majority of communications data requests from public authorities were for subscriber
information. This request would seek to identify the user of a telephone or email address,
for example. The statistics show that 89% of communications data items obtained related
to telephony and that in 96% of cases, the applicant identified the subject of the request as
the suspect of their investigation.
