To ignore the latest legal challenge of Myuran Sukumaran and Andrew Chan and send them for execution would betray the spirit of human rights, their lawyer says.
Todung Mulya Lubis joined human rights advocates in Jakarta on Wednesday to explain the latest action lodged with the Constitutional Court last week.
The rights groups have brought the action because legally, foreigners can't challenge the Constitutional Court.
The application seeks to challenge that point, as well as the fact no reasons were given when Indonesian President Joko Widodo refused mercy to the Bali Nine pair, based only on the fact they're drug offenders.
Attorney-General HM Prasetyo says the court action won't stop the executions, because it can only impact future cases.
His spokesman says they're considering carrying out the executions after next week's Asian-African Conference in Jakarta.
Mr Lubis says he's tried to meet with Mr Prasetyo to underline that it's an important case, and a matter of life or death.
"I respectfully ask the attorney-general to respect the judicial review process because it is a legal process," he told reporters.
The case is about more than the two Australians, he argued.
"If you have thought this over and over, if you, if you've thought of the general picture, it's not only for the two young men, it's for the others," he said.
"You have to give reasons, you have to make it more humane.
"A clemency rejection is not a means to dehumanise."
Mr Lubis also expressed his disappointment in Indonesia's use of the death penalty in light of Saudi Arabia's execution on Tuesday of Indonesian domestic worker Siti Zaenab.
Jakarta had fought hard to save the woman, and Mr Lubis fears its inconsistent position can only weaken its leverage to negotiate for others on death row.
Al Araf of rights group Imparsial agreed.
"It's funny when its domestic politics is different with its foreign politics," he said of the government.
"This has made it difficult for Indonesian diplomacy when fighting for the lives of Indonesian citizens abroad."
Haris Azhar of rights group Kontras slammed the Indonesian government's conduct and the president's "one size fits all" clemency decisions.
"With the Supreme Court website, all cases on death penalty suddenly can't be accessed," he said.
"This matter of the death penalty has been made into some kind of secrecy.
"This is an evil practice, an abuse of authority, maladministration, that makes it difficult for someone to defend."
