LIMA - Ex-president Alberto Fujimori's defence lawyer on Tuesday asked the Supreme Court to revoke his client's 25-year prison sentence for human rights abuses on the second day of hearings to review the conviction.

"None of the 10 pieces of evidence that went to determine his guilt as mastermind of premeditated murder have to do with the issue of him giving the order for the Barrios Altos and La Cantuta" killings in 1991 and 1992," attorney Cesar Nakazaki told the panel.

The defence lawyer also asked for an annulment of Fujimori's conviction in the kidnapping of a journalist and a businessman in 1992, also because he claimed there was not enough evidence to prove that the former president had ordered the abductions.

Nakasaki asked chief supreme justice Duberli Rodriguez to rule for a retrial on both cases.

The three-day hearing is taking place in a special courtroom inside the headquarters of the National Police special operations division, where Fujimori is imprisoned.

The review wraps up on Wednesday, with the prosecution taking time to rebut the defence charges, then more time for a counter-rebuttal.

The court then has up to 30 working days to issue a ruling that cannot be appealed.

Fujimori, 71, has been found guilty in four trials since he was extradited from Chile in September 2007.

The former strongman's political downfall began in 2000, 10 years after he was first elected to office, when a video of his spy chief Vladimiro Montesinos was broadcast on television, showing Fujimori's right-hand man buying off an opposition lawmaker.

Soon after, Fujimori fled to Asia and resigned via fax from a Tokyo hotel.

Congress refused to accept his resignation and instead voted to sack him and ban him from public office for 10 years.

But the ex-president's political legacy appears far from extinguished.

Fujimori's daughter Keiko, who enjoys her own political career, is likely to run for the Peruvian presidency in 2011 and - if successful - she has vowed to pardon her father.
