Drawback claim time limit amended to exclude cases where a claim under rule three or rule four is made. Amendment replaces the words 'he may within three months' in rule 7(1) with 'he may, except where a claim for drawback under rule 3 or rule 4 has been made, within three months', thereby creating an exception to the ordinary three month filing timeframe for cases where a claim under rule 3 or rule 4 has been made.
