"However, applying general principles and on reading the aforesaid judgments, we find that this Court, has repeatedly taken the view that the burden of proof is on the claimant to show that he had worked for 240 days in a given year. This burden is discharged only upon the workman stepping up in the witness box. This burden is discharged upon the workman adducing cogent evidence, both oral and documentary. In cases of termination of services of dailywaged earners, there will be no letter of appointment of termination. There will also be no receipt of proof of payment. Thus in most cases, the workman (the claimant) can only call upon the employer to produce before the Court the nominal muster roll for the given period, the letter of appointment of termination, if any, the wage register, the attendance register, etc. Drawing of adverse inference ultimately would depend thereafter on the facts of each case."
