If:
(a) a special security direction (the original direction ) has been given to a person; and
(b) the original direction ceases to be in force because it has been in force for a continuous period of 6 months (see subsection 71(2));
the Secretary must not give a special security direction to the person that is the same as, or substantially similar to, the original direction during the period of 6 months after the original direction ceases to be in force.
