Director of Public Prosecutions v Lennon

Director of Public Prosecutions v Lennon

The court held that implied consent to receive emails does not cover emails sent in bulk with the intent to disrupt or overwhelm the recipient's system. Such actions constitute unauthorised modification under section 3(1) of the Computer Misuse Act 1990. The District Judge was wrong to find there was no case to answer, and the matter should be remitted for further hearing.
