Andrew Chan and Myuran Sukumaran were convicted in 2006 as the ringleaders of a plot to smuggle heroin out of Indonesia.
They had both challenged the Jakarta administrative court’s decision not to hear an appeal against President Joko Widodo’s refusal to grant them clemency.
“There is no more legal recourse,” Novarida, head of the state lawyers team, told reporters after the verdicts were delivered dryly in a court packed with lawyers and journalists.
However, the pair’s lawyer said they would take their case to the constitutional court. “They have the right to live, and the state attorney knows that [the law] allows them to defend their lives,” Leonard Arpan told reporters.
The Australians are among 10 drug convicts due to be executed by firing squad on the prison island of Nusakambangan.
Others in the group include citizens of France, Brazil, the Philippines, Ghana, Nigeria, and Indonesia.
Widodo denied clemency to the convicts despite repeated pleas from Australia, Brazil, and France.
Australia’s minister for foreign affairs, Julie Bishop, voiced disappointment at the latest setback and said in a statement that Canberra would continue to use all diplomatic options to seek a stay of execution.
Sukumaran and Chan, who were not in court yesterday, had sought in February to challenge the president’s blanket rejection, with their lawyers arguing that he did not give due consideration to each case.
However, the administrative court originally dismissed their case on the grounds it did not have the legal authority to assess it.
The attorney general is awaiting the outcome of legal appeals by three remaining death row inmates before setting a date for executions. His office has previously said the intention is for all the executions to be carried out together, but they could be conducted in batches.
Indonesia has harsh penalties for drug trafficking and resumed executions in 2013 after a five-year gap.
Widodo has pledged no mercy for drug offenders, saying Indonesia faces a “drug emergency”. The country is a major destination for drugs trafficked in the region.
Australia has made repeated calls for mercy on behalf of Sukumaran and Chan, but Widodo has refused to change his stand, turning down an offer of a prisoner exchange and to have the Australian government bear the cost of the convicts serving life sentences.
