DHAKA, Bangladesh (AP) — A labor court in Bangladesh’s capital Monday sentenced Nobel Peace Prize winner Muhammad Yunus to six months in jail for violating the country’s labor laws.

Yunus, who pioneered the use of microcredit to help impoverished people, was present in court and was granted bail. The court gave Yunus 30 days to appeal the verdict and sentence.

Grameen Telecom, which Yunus founded as a non-profit organization, is at the center of the case.

Sheikh Merina Sultana, head of the Third Labor Court of Dhaka, said in her verdict that Yunus’ company violated Bangladeshi labor laws. She said at least 67 Grameen Telecom workers were supposed to be made permanent employees but were not, and a “welfare fund” to support the staff in cases of emergency or special needs was never formed. She also said that, following company policy, 5% of Grameen’s dividends were supposed to be distributed to staff but was not.

Sultana found Yunus, as chairman of the company, and three other company directors guilty, sentencing each to six months in jail. Yunus was also fined 30,000 takas, or $260.

Yunus said he would appeal.

“We are being punished for a crime we did not commit. It was my fate, the nation’s fate. We have accepted this verdict, but will appeal this verdict and continue fighting against this sentence,” the 83-year-old economist told reporters after the verdict was announced.
