Official Secrets Act

The Official Secrets Act is a set of United Nations Space Command regulations that involve the protection of confidential information. The act was passed on November 23, 2550.

The Official Secrets Act mandates the confidentiality and the nondisclosure of any contents of any Messenger Satchel. After Tom Muir was taken aboard the ONI prowler Port Stanley, Captain Serin Osman exaggeratively told Muir that even breathing on such a vessel was a breach of the Official Secrets Act.
