19. There can be no dispute that the period of limitation set out in a special law, which provides for remedies and appeals, has to be construed in its terms and without reference to the Limitation Act, if it contains specific provisions delineating the time or period within which applications or appeals can be preferred, and confines the consideration of applications for condoning the delay to a specific number of days. Undoubtedly, in such cases, the Limitation Act would be inapplicable. There are several previous judgments of this Court holding that where periods of limitation are prescribed under special laws, appeals that exceed the period granted and are within the extended period of limitation in the special law, can be entertained at the discretion of the tribunal, or court concerned and the Limitation Act would not apply upon expiry of such extended period. This Court holds that there is merit in the contention of the Union that the provisions of the Limitation Act are inapplicable. This is, however, not dispositive of the issue; the next question is whether there is merit in the appellant's argument that NGT should have considered the issue of whether the appeal was filed within the extended period prescribed under the proviso to Section 16 i.e. within sixty days after the expiration of the initial 30 day period, required in the main provision.
