Sarath Fonseka led troops to victory last year over the Tamil Tigers, but then fell out with the president
A military court has convicted Sri Lanka's former army chief for corruption, his lawyer says.
Sarath Fonseka was found guilty of breaching arms procurement guidelines.
Last month, he was stripped of his rank and pension after being convicted of engaging in politics while in uniform. He denied all the charges.
He led troops to victory last year over the Tamil Tigers, but fell out with the president after standing against him in polls, unsuccessfully.
He faces more charges in civilian courts.
Mr Fonseka's lawyer, Sunil Watagala, told BBC Sinhala: "They have decided that Fonseka is guilty of four charges. Therefore we have decided to go to the court of appeal to challenge that decision.
"They are still considering the sentence. They are going to meet again for the sentence. He said he doesn't know the exact date."
As the case has been handled by a military court, President Mahinda Rajapaksa, as commander in chief of the armed forces, must approve the eventual sentence.
If Mr Fonseka, an MP, is jailed for any longer than three months he would lose his parliamentary seat.
