The probe agency moved the application before special judge O P Saini stating that the summons issued to Malaysian business tycoon T Ananda Krishnan and Malaysian national Augustus Ralph Marshall could not be served upon them.
Besides Maran brothers, Krishnan and Marshall, the court had summoned four companies -- Sun Direct TV Pvt Ltd, Maxis Communication Berhad, South Asia Entertainment Holding Ltd and Astro All Asia Network PLC -- as accused in the CBI's case.
The court had earlier issued summons to accused while taking cognisance of Enforcement Directorate's (ED) charge sheet against the six accused under the provisions of the Prevention of Money Laundering Act (PMLA).
It had said that there was "enough incriminating material" to proceed against the accused.
"It is submitted that possibility of hampering the investigation and tampering with the evidence by the applicant may not be ruled out in the investigation," ED said, adding that the bail application deserved to be rejected.
The court has put up both the matters for hearing on August 27.
In the money-laundering case, ED had summoned Maran brothers, Krishnan and Marshall and two firms SAFL and Sun Direct TV Pvt Ltd (SDTPL) as accused in case.
