You can sue for anything; just not always successfully. That said ...
This appears to be trespass which I think is a tort (entering a part of property, the phone, that was off limits and without consent). You can sue for that.
It's also in the same respect contrary to the UK Computer Misuse Act (crime) AFAICT [story appears to be in the UK, or is it just UK entries in the addressbook]. That would probably hinge on the consent to access the particular files duplicated.
Then there's database rights (tort?), a sort of copyright for databases. [Copyright wouldn't apply as it's not a creative work].
Harassment (tort I think) and infringement of the right to a private life as enshrined in the ECHR (crime) seem to be causes to object as well.
As the calls were business motivated then failure to check against a telephone cold-call blacklist could also generate extra fines.

Seems there's much that could be sued for.
