A division bench of Justices Revati Mohite Dere and Gauri Godse quashed the sessions court's 2013 judgment acquitting Sharma, terming it as "perverse" and "unsustainable".
Special NIA Judge A M Patil, after perusing the report of an expert committee of doctors, said it has been found Sharma was in "stable condition and can be discharged."
The NIA has claimed Sharma was fit and was misusing the hospital facility under the guise of ailments.
