Indonesia has rejected the last-ditch appeal to spare 'Bali Nine' Australian drug smugglers Myuran Sukumaran and Andrew Chan from execution by a firing squad. 

An Indonesian administrative court on Monday ruled against two appeals to let the duo legally challenge President Joko Widodo's rejection of their clemency pleas. 

The appeals were a last-ditch attempt by Chan and Syukumaran to seek to overturn Widodo's refusal of clemency, after both claimed that the Indonesian President had not given proper consideration to their pleas.

The court said that presidential decrees on clemency did not fall in its jurisdiction, according to Fairfax agency. 

With these final appeals, Chan and Syukumaran have exhausted all legal avenues to save themselves from execution. 

Chan and Sukumaran, said to be ringleaders of the 'Bali nine' drug trafficking gang, were given death penalty in 2006 for attempting to smuggle about 8 kilogram of heroin out of Indonesia.

The two were shifted to the  infamous Nusakambangan island last month for their imminent execution by a firing squad. 

No date has been set for the execution yet. 

The pair will be executed along with 8 other drug convicts from countries such as  France, Brazil and Nigeria. 

Australia has repeatedly denounced Indonesia's decision to execute the two men.
