The Supreme Court in its order does not give any time frame and only says that she is directed to surrender along with the other co-convicts Ilavarasi and Sudhakaran. An interpretation of this would be that she is directed to surrender immediately.
Sasikala's legal advisors have told her to surrender before the court and only then go ahead with the review petition as well as an application seeking more time on health grounds. The court can view such misconduct very seriously if applications are filed before the convict surrenders.
Sasikala is expected to take a flight to Bengaluru later on Wednesday and surrender before the court. She will then be taken to the central jail at Parapanagrahara and is likely to be lodged in the same barrack as Jayalalithaa and B S Yeddyurappa were lodged.
