After hearing learned counsel for the parties and perusing the impugned order, we are of the opinion that the Divisional Canal Officer has acted illegally, while allowing the application of respondent No.4 filed under Section 55 of the Act for change of wari', without taking into notice that in earlier litigation between the parties, the claim made by respondent No.4 for fixing his wari' after the `wari' of the petitioner was specifically rejected. A perusal of the order dated 13.10.2004 (Annexure P-4) passed by the Deputy Collector, Gohana, clearly indicates that he has rejected the application of respondent No.4 while taking into consideration the earlier litigation between the parties, but the Divisional Canal Officer, even without considering the fact that the earlier litigation between the parties was finalised, has illegally allowed the appeal, while observing that claim of respondent No.4 is genuine. In our opinion, once the dispute between the parties under Section 55 of the Act has been finalised, the same cannot be re-opened on the fresh application made by the defeated person.
