6.—(1) The Department may extend the time limit specified in regulation 5(1) (revision on any grounds) for making an application for a revision if all of the following conditions are met.
(2) The first condition is that the person wishing to apply for the revision has applied to the Department at an appropriate office for an extension of time.
(3) The second condition is that the application—
(a)explains why the extension is sought;
(b)contains sufficient details of the decision to which the application relates to enable it to be identified; and
(c)is made within 13 months of the latest date by which the application for revision should have been received by the Department in accordance with regulation 5(1)(b)(i) to (iii).
(4) The third condition is that the Department is satisfied that it is reasonable to grant the extension.
(5) The fourth condition is that the Department is satisfied that due to special circumstances it was not practicable for the application for revision to be made within the time limit specified in regulation 5(1)(b)(i) to (iii).
(6) In determining whether it is reasonable to grant an extension of time, the Department must have regard to the principle that the greater the amount of time that has elapsed between the end of the time limit specified in regulation 5(1)(b)(i) to (iii) and the date of the application, the more compelling should be the special circumstances on which the application is based.
(7) An application under this regulation which has been refused may not be renewed.
