Special circumstances may arise that require additional security measures beyond those otherwise required under this Act.

This Division   allows the Secretary to address such circumstances by issuing special security directions. The Division   establishes time limits for such special security directions. As a general rule, a special security direction ceases to have effect after it has been in force for 3 months.

Failing to comply with a special security direction is an offence.

In addition, disclosing such a direction in certain circumstances is also an offence.
