This appeal is directed against the award dated 24.4.2004 propounded by Commissioner Workmens Compensation Act (Assistant Labour Commissioner) Kishtwar. By the aforesaid award an amount of Rs, 60,000/- has been awarded as compensation to the respondent. 2. On going through the award impugned, it is found that the Commissioner has decided the claim petition after analytical appreciation of evidence in its proper perspective. No substantial question of law is involved in this appeal nor same has been pointed out by Mr. S. C. Gupta, AAG, learned counsel appearing for the appellant during course of debate. It is pertinent to point out that appeal under section 30 of Workmens Compensation Act lies to the High Court only on a substantial question of law and the High Court does not function as a regular court of appeal with liberty to re-appreciate the evidence. Whether mis-appreciation of evidence raises a question of law depends upon the circumstances of each case. In such a case, it cannot be contended that Commissioner was bound, as a matter of law, to beheve or disbeheve the evidence. So far as credibility of evidence is concerned, it is mainly a matter for the Commissioner and not for the High court sitting in appeal. 3. To be a substantial question of law, it may be great public importance or one of which raises so frequently as to affect a large class of people or be basic to the operation of the Act. 4. In the facts and circumstances of the case, the appeal is not maintainable for want of substantial question of law involved and is accordingly dismissed.
