appellant No.1 while driving the offending vehicle. Merely because challan had been presented in the criminal case, was not sufficient to decide Issue No.1 in favour of the claimants. The driver of the offending vehicle could be acquitted in the criminal case. So far as the claim petition was concerned, the claimants were required to examine the eye-witness to establish the manner of accident. Opposite party would have got an an opportunity to crossexamine the eye-witness to test his testimony with regard to the manner of accident. In the absence of examination of the eyewitness before the Tribunal, the opposite party has been denied its valuable right to cross-examine the said witness and establish their own plea. In case it is to be held that there was no need to examine an eye-witness and the claim petition could be allowed merely on the basis of the documents attached with the challan in the criminal case, then there is no need even to issue notice to the opposite party and compensation could be granted merely on the filing of the claim petition alongwith challan papers. However, it cannot be done so. Before a claim petition could be allowed, the other party has to be heard. Claimants have to examine witnesses to prove the issues qua which onus is upon them. Other party gets a chance to cross-examine the witnesses and test the truthfulness of the said witnesses.
