|Abba Abacha and Late Sani Abacha|
Abba Abacha was sentenced to a suspended jail term of two years and his assets confiscated in the initial court hearing, but he won an appeal at the Swiss Federal Tribunal which ordered that the sentence be annulled and a retrial held due to procedural irregularities and the fact that the accused had been unable to attend the trial because he was unable to obtain a visa in time.
The Swiss Federal Tribunal annulled the sentence and ordered the retrial on the grounds that Abacha's rights had been violated.
In June 2010, Geneva police's court found Abba Abacha guilty of participating in his family's pillage of Nigeria’s assets.
Abba Abacha was ordered to return $350m of illegally gained assets at his trial last year in the police court in Geneva.
Nigerian government had asked the Swiss government in 1999 to help recover the money, much of which was thought to be hidden in Swiss banks.
Switzerland has so far handed back about $700m to Nigeria.
His father, Sani Abacha who took over power in 1993 and ruled till he died in 1998, was believed to have syphoned about $2.2 billion from the Central Bank, which his sons Abba and his brother Mohammed controlled.
