2. For having bird’s eye view of the matter, necessary facts, as emerge from the record are that the claimants filed a petition under S.22 of the Act before learned Court below under, praying therein for compensation to the tune of Rs.5.00 lakh alongwith interest on account of death of late Tulsi Ram. Claimants alleged that deceased workman died during course of employment with the appellant and received injuries due to fall. Deceased was admitted in Zonal Hospital, Bilaspur on 16.12.2004, from where he was referred to PGI Chandigarh and remained admitted as indoor patient from 16.12.2004 to 20.12.2004, but unfortunately, he succumbed to injuries on 20.12.2004. Claimants claimed that since the accident was well within the knowledge of the appellant, there was no need for them to serve notice upon the appellant. Claimants claimed that the deceased was working as a Chowkidar with the I&PH Department and was getting salary to the tune of Rs.6500/- per month at the time of his death. Appellant, while refuting aforesaid claim of the claimants, specifically denied that the deceased died on account of injuries sustained by him, rather, claimed that he died a natural death due to cardiac arrest. Appellant claimed that as per accident report, deceased had suffered injuries in his left leg on 15.1.2040, as per post-mortem report, cause of death is cardiac arrest, as such, there is no causal connection between death and injuries sustained by deceased, hence, appellant is under no obligation to compensate
