The Data Inspectorate considers that secret data reading interferes with the individual's personal integrity, as the authority has previously pointed out in a referral opinion that rejected the investigation proposal.

"In our opinion, it should only be used in serious crimes that can affect the security of the state such as terrorist crimes, and very serious organized crime when other coercive means are not sufficient," says Jonas Agnvall, lawyer at the Data Inspectorate.

The Data Inspectorate is strongly critical of the police being able to resort to coercive means that enable a total mapping and monitoring of private individuals.

It is proposed that the secret data interception is used when the penalty value exceeds two years in prison is too low a limit, Agnvall believes.
