A bench headed by Chief Justice H L Dattu said Setalvad and her husband Javed Anand would be protected from the arrest till the matter is heard tomorrow.
Senior advocate Kapil Sibal orally mentioned about the imminent arrest of the couple, soon after Gujarat High Court rejected their anticipatory bail.
Sibal along with advocate Aparna Bhat mentioned the plea, when the bench, which also comprised justices A K Sikri and Arun Mishra, was hearing another case.
The bench said that the appeal against the High Court decision could be filed in the course of the day.
