The show cause notice must state the following—

that the licensee may be required to dispose of a particular category H weapon or class of category H weapon (the proposed action);

the ground for the proposed action;

an outline of the facts and circumstances forming the basis for the grounds;

an invitation to the licensee to show, within a stated period (the show cause period), why the proposed action should not be taken.

The show cause period must be a period ending at least 28 days after the day the show cause notice is given to the licensee.
