A court in Afghanistan has cut by at least half the sentences of three US citizens jailed for torturing Afghans and running a private jail in Kabul.
Idema (centre) complained that American lawyers were not present
But the court rejected their appeal for the convictions to be overturned.
Jonathan Idema, Brent Bennett and Edward Caraballo were sentenced last September after a chaotic trial.
Branded by the US as a bounty hunter, Idema has said his work was approved by Afghan and US authorities, a claim that US officials have denied.
Idema and Bennett's sentences were reduced from 10 years to five and three respectively, reports quoted one of the four judges hearing the case as saying.
Caraballo's was cut from eight to two years.
It is not yet clear why the sentences have been reduced.
Idema was known in Afghanistan as a mysterious figure, often seen clad in combat gear and dark glasses and heavily armed.
He was one of many former special forces soldiers working privately in Afghanistan - some to provide security, others acting as bounty hunters attracted by the millions of dollars in rewards offered for Osama Bin Laden and other top al-Qaeda men.
The three men were arrested in July 2004 after Afghan forces raided a house in a Kabul neighbourhood and discovered eight Afghan men being held captive.
Idema said his group was tracking down terror suspects with the co-operation of Afghan and US authorities.
The US said it had received one prisoner from Idema but the Pentagon denied any ties to him.
Nato forces also said they had been duped into helping the group on three occasions.
Correspondents say their trial was often chaotic and marred by poor translation.
Defence lawyers said the Afghan legal system was not fit to try the men.
The Americans are serving their sentences in Kabul's Pul-e Charkhi prison. They have a heated and carpeted cell with satellite television.
