"29. We have bestowed our consideration to the rival submissions and the submissions made by Mr. Ranjit Kumar commend us. True it is that at the time of consideration of the applications for discharge, the court cannot act as a mouthpiece of the prosecution or act as a post-office and may sift evidence in order to find out whether or not the allegations made are groundless so as to pass an order of discharge. It is trite that at the stage of consideration of an application for discharge, the court has to proceed with an assumption that the materials brought on record by the prosecution are true and evaluate the said materials and documents with a view to find out whether the facts emerging therefrom taken at their face value disclose the existence of all the ingredients constituting the alleged offence. At this stage, probative value of the materials has to be gone into and the court is not expected to go deep into the matter and hold that the materials would not warrant a conviction. In our opinion, what needs to be considered is whether there is a ground for presuming that the offence has been committed and not whether a ground for convicting the accused has been made out. To put it differently, if the court thinks that the accused might have committed the offence on the basis of the materials on record on its probative value, it can frame the charge; though for conviction, the court has to come to the conclusion that the accused has committed the offence. The law does not permit a mini trial at this stage."
