A Sky News journalist accused of hacking into the emails of fake canoe death couple John and Anne Darwin will face no further action.
Gerard Tubb allegedly accessed their emails but the CPS said it was uncertain whether this had taken place in the UK, and prosecution would not be in the public interest.
Prosecutors also said that the public interest would outweigh any alleged criminal activity.
Sky News declined to comment.
Mr Darwin admitted faking his own death in March 2002 to allow his wife to make fraudulent insurance and pension claims.
The couple planned a new life in Panama, but were jailed in 2008 after jurors heard how they deceived the police, a coroner, financial institutions and even their family.
