42.3. Since there is no period of limitation, it gives right to the workman to raise the dispute even belatedly. However, if the dispute is raised after a long period, it has to be seen as to whether such a dispute still exists? Thus, notwithstanding the fact that law of limitation does not apply, it is to be shown by the workman that there is a dispute in praesenti. For this purpose, he has to demonstrate that even if considerable period has lapsed and there are laches and delays, such delay has not resulted into making the industrial dispute cease to exist. Therefore, if the workman is able to give satisfactory explanation for these laches and delays and demonstrate that the circumstances disclose that issue is still alive, delay would not come in his way because of the reason that law of limitation has no application. On the other hand, if because of such delay dispute no longer remains alive and is to be treated as “dead”, then it would be non-existent dispute which cannot be referred.
