Dear Pramod: Reexamination of a witness is permissible. In DE, the process of recording evidence of a witness essentially involves three steps, firstly the examination in chief, where the witness is examined by the party producing him, next the cross -examination which is done by the opposite party and finally reexamination by the original party which had produced the witness to the extent of any new point which had come up in the cross-examination and it could only be clarificatory. However if any new point arises, as pointed out by Mr. Sudhakar then cross-examination has to be allowed if so desired by the opposite party.
