receipt or proof of payment. Thus in most cases, the workwoman (claimant) can only call upon the employer to produce before the court the nominal muster roll for the given period, the letter of appointment or termination, if any, the wage register, the attendance register etc. Drawing of adverse inference ultimately would depend thereafter on facts of each case. The above decisions however make it clear that mere affidavits or self-serving statements made by the claimant/workwoman will not suffice in the matter of discharge of the burden placed by law on the workwoman to prove that he had worked for 240 days in a given year. The above judgments further lay down that mere non-production of muster rolls per se without any plea of suppression by the claimant workwoman will not be the ground for the tribunal to draw an adverse inference against the management. Lastly, the above judgments lay down the basic principle, namely, that the High Court under Article 226 of the Constitution will not interfere with the concurrent findings of fact recorded by the labour court unless they are perverse. This exercise will depend upon facts of each case.”
