There is no capacity to extend the timeframe for an individual to apply for promotion review.
There are NO exceptions.
The Merit Protection Commissioner can extend the timeframe for 'a class of employees' if there is a general reason affecting their capacity to apply within the timeframe (Regulation 5.9 (1)(b)(i)(B)).
The usual timeframe is 14 days. You must check the notice in the Gazette in which the promotion appears. Please note, however, the timeframe is usually extended over the Christmas and New Year period each year.
