Revocation of SLP

Dear Dr.Tripathi, in the case of Balkrishna Vs ramaswamy AIR 1965 SC 195, the apex court held that it can not be stated asa general preposition the leave once granted cannot be revoked. But where SLP has been granted after notice to the respondent and giving him a hearing the SC will not revoke the leave, except in extraordinary circumstances. But, where the SLP was granted after ex parte hearing, it would be open to the Respondent to urge at the final hearing that leave should be revoked or that the appellant had not complied with the rules of the Court. Hindustan Commercial Bank vs Bhagwan das AIR 1965 SC 1142.

thanks !
