A four-judge bench headed by Chief Justice P Sathasivam issued notice to the Centre and Delhi government on a curative petition filed by Bhullar's wife Navneet Kaur.
The bench also comprising justices R M Lodha, H L Dattu and S J Mukhopadhaya directed the Institute of Human Behaviour and Allied Sciences (IHBAS), where Bhullar is being treated, to file a medical report within a week on the condition of the death convict who is alleged to be suffering from a mental illness.
"We direct Institute of Human Behaviour and Allied Sciences to send to us a report on condition of Devinderpal Singh Bhullar within a week," the bench said.
The plea of Bhullar's wife for commutation of death sentence assumes significance in view of the apex court's January 21 verdict holding that inordinate and inexplicable delay by government in deciding mercy plea of death row convicts can be a ground for commuting their sentence.
Bhullar was convicted and awarded death penalty for triggering a bomb blast in New Delhi in September 1993, which killed nine persons and injured 25 others, including then Youth Congress president M S Bitta.
