Decision of the Court
The Court found that the retention of the applicant’s DNA profile, fingerprints and photograph
amounted to an interference with his private life which had pursued the legitimate purpose of the
detection, and therefore, prevention of crime.
It emphasised the importance of examining privacy rights where the powers vested in the State
were obscure and where the technology available was continually becoming more sophisticated. For
example, the technology regarding photographs and facial mapping had already moved on since the
case had been examined by the domestic courts.
It went on to examine whether the interference in the applicant’s privacy rights had been justified,
reiterating that the national authorities had to be given leeway (“margin of appreciation”) when
making that assessment. A strong consensus in the member States’ approach to retaining data of
those convicted of an offence would narrow that margin of appreciation.
The Court considered that the majority of member States had regimes which put a time-limit on
retaining the biometric data, that is, fingerprints and DNA profiles, of convicted persons. The UK was
one of the few Council of Europe jurisdictions to permit indefinite retention of DNA profiles2. The
margin of appreciation, in particular in respect of DNA profiles, had therefore been narrowed.
The Court underlined though that the duration of the retention was not conclusive in assessing
whether a State had overstepped the acceptable margin of appreciation in establishing its retention
regime. There was not the same risk of stigmatisation in retaining the data as in
What was decisive was the existence and functioning of safeguards. Having chosen to allocate itself
the most extensive power of indefinite retention, the State had put itself at the limit of the margin of
appreciation. So, it had to ensure that certain safeguards were present and effective for the
applicant.
However, the applicant’s biometric data and photographs had been retained without reference to
the seriousness of his offence and without regard to any continuing need to retain that data
indefinitely. Moreover, the police in Northern Ireland were only empowered to delete biometric
data and photographs in exceptional circumstances. Therefore the applicant could not request a
review of the retention of his data, as there was no provision permitting deletion if conserving the
data no longer appeared necessary in view of the nature of his offence, his age, or the time that had
elapsed and his current personality.
2 Four out of 31 Council of Europe member States surveyed (Cyprus, Ireland, North Macedonia and Montenegro) have indefinite retention
periods of DNA profiles following a conviction for a minor criminal offence. See paragraph 53 of the judgment.
