Indonesia's Attorney-General is set to be investigated over the recent execution of four men, with the country's ombudsman saying there appeared to be a "maladministration" in the carrying out of the death penalty.
Ricky Gunawan, lawyer for Nigerian man Humphrey Jefferson Ejike Eleweke, who was shot by firing squad in the early hours of July 29, filed a report to the country's ombudsman on Monday alleging the executions were "illegal" as they violated the country's clemency law.
In accepting the report, Commissioner for the Ombudsman Lely Pelitasari Soebakty said it appeared a "maladministration" had occurred in the carrying out of the executions.
"We will investigate this ... We need time to see the document first and because the report to the Ombudsman is personal in nature, we need to verify the document," she told reporters in Jakarta.
At least two of the four men who were shot last month by a firing squad filed last minute clemency requests to President Joko Widodo in the days before their deaths.
The country's clemency law stipulates an execution can only be carried out once a prisoner is informed by the president that such a plea has been rejected.
The men received no such notification.
Mr Gunawan has previously told AAP that when he informed prosecutors of this, they pointed him to a now defunct section of the law which stipulated clemency requests needed to be filed within a year of the outcome of a person's final appeal.
But this section was repealed in June this year by the Constitutional Court, which found the time limitation on clemency requests had the potential to violate a person's constitutional rights.
Mr Gunawan said they hoped that by reporting matter to the ombudsman, President Widodo would be properly informed of what occurred.
"When the Ombudsman has given its recommendation, the president will definitely read (it) so when Attorney-General tries to deny what has happened, he can't run from it."
The Attorney-General HM Prasetyo has been contacted for comment.
