Prosecutors in Indonesia today will begin their response to Bali Nine drug courier Scott Rush's case against the death penalty.

Prosecutors in Indonesia today will begin their response to Bali Nine drug courier Scott Rush's case against the death penalty.

Former Australian Federal Police Commissioner Mick Keelty told the Denpasar District Court this month that Rush's role in the foiled 2005 plot to smuggle more than eight kilograms of heroin out of Bali was only that of a courier.

Rush was originally sentenced to life in prison but Indonesia's Supreme Court increased his sentence at appeal to death.

If Rush's final appeal fails his last hope of survival will be to seek clemency from Indonesian President Susilo Bambang Yudhoyono who's not known for showing mercy to drug smugglers.
