Tribunal. In the facts of the present case, admittedly, the order dated 23rd September, 2011 (and which was impugned in the Petitioners' appeal) was served upon the Petitioners on 20th February, 2012. We are, therefore, clearly of the view that the time to file the appeal started to run from the aforesaid date (i.e. 20th February, 2012). We are unable to accept the submission of Mr. Kamat that when an appeal is filed by a third party, then, not only a copy of the order but also the papers and proceedings should be served on the party, failing which the time does not start to run. To our mind, that would clearly violate the plain language of the statute and by the process of judicial interpretation we cannot supply words therein, which are otherwise clear and unambiguous, and alter the mandate of the legislature. It is pertinent to note that there was no bar or fetter on the Petitioners from filing their appeal once they received a copy of the order on 20th February, 2012. Instead of filing their appeal, the Petitioners engaged in correspondence with the authorities. We do not think that entering into such correspondence would stall the time to run against the Petitioners to file their appeal. We, therefore, have no hesitation in rejecting the contention of Mr. Kamat that there was no delay in filing the appeal.
