The five-year sentence included two years suspended and the court did not order Keirvel
to begin his sentence right away. The court also confirmed that he must pay back the billions he lost on uncovered bets on financial markets, although the bank has said it will not force him to pay it all.
His lawyer, David Koubbi, said he might appeal to a higher court, describing the verdict as a “deplorable injustice”.
Kerviel changed his lawyer in March, hiring Koubbi, who represented writer Tristane Banon when she sued former IMF chief Dominique Strauss-Kahn for rape before dropping charges earlier this month.
Koubbi launched two countersuits against the bank, accusing it of manipulating secret recordings to cover up his superior’s knowledge of his actions and of recovering a third of the money Kerviel was ordered to repay through a tax write-off.
The bank has hit back with two suits for malicious falsehood.
In 2010 Kerviel was convicted of breach of trust, forgery and entering false data into computers.
