Lim Siong Khee v Public Prosecutor: Computer Misuse Act & Unauthorized Access to Email Account

In Lim Siong Khee v Public Prosecutor, the High Court of Singapore heard an appeal by Mr. Lim Siong Khee against his conviction under Section 3(1) of the Computer Misuse Act for unauthorized access to Ms. Chong Yan Cheng's email account. The District Judge had found Mr. Lim guilty of accessing the account without Ms. Chong's consent and sending a defamatory email. Chief Justice Yong Pung How dismissed the appeal, holding that the relevant authorization for access under the Act is that of the account holder, not the system provider, and enhanced Mr. Lim's sentence from five to twelve months' imprisonment.
