JUDGMENT Allsop, J. - The provisions of Section 537 of the Criminal Procedure Code are mandatory and this Court could not interfere without finding that there had been a substantial error of justice due to the irregularities mentioned in the report of the learned Judge. It is quite clear that the person who was convicted of selling adulterated ghee was not prejudiced in any way by any irregularity in the summons. He knew very well what the facts were which were alleged against him and who had been responsible for his prosecution. Even when he attempted to appeal to the learned Judge he did not make any complaint about the procedure of the magistrate. He said simply that the evidence for the prosecution did not warrant his conviction, that the lower Court had erred in weighing the evidence and that the sentence was too severe. It was never the intention of the legislatuie that persons who committed offences should escape punishment merely on technical grounds which did not affect the substantial justice of a case. The matter has been discussed in the case of Hira Lal v. Emperor 1938 AWR (H. C ) 335: A 1 R 1938 All 495. There is no reason to interfere. The reference is rejected.
