Justice Joymalyo Bagchi passed an interim stay on the criminal proceedings which had been initiated by a city court order on Supriyo's alleged derogatory comment against Moitra during a television debate.
The High Court stayed the proceedings against him following a prayer by Supriyo.
While passing the order Justice Bagchi observed that public representatives should exercise restraint in making remarks about a person.
He observed that Indian Parliament had seen revered parliamentarians like Hiren Mukherjee and Atal Behari Vajpayee and said that an elected representative should be cautious about the language he uses.
An Alipur court judge had issued a bailable warrant against Supriyo following his failure to appear in connection with the case filed under Section 509 (word, gesture or act intended to insult the modesty of a woman) of the IPC.
The Union minister had challenged it in the High Court.
