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.

A defense lawyer criticized the ruling, saying it was unfair and against the law. “We have been deprived of justice,” said attorney Abdullah Al Mamun.

But the prosecution was happy with what they said was an expected verdict.

“We think business owners will now be more cautious about violating labor laws. No one is above the law,” prosecutor Khurshid Alam Khan told The Associated Press.

Grameen Telecom owns 34.2% of the country’s largest mobile phone company, Grameenphone, a subsidiary of Norway’s telecom giant Telenor.

As Yunus is known to have close connections with political elites in the West, especially in the United States, many think the verdict could negatively impact Bangladesh’s relationship with the U.S.

But Foreign Secretary Masud Bin Momen on Monday said relations between Bangladesh and the U.S. would likely not be affected by an issue involving a single individual.

“It is normal not to have an impact on the state-to-state relations for an individual,” the United News of Bangladesh agency quoted Momen as saying.

The Nobel laureate faces an array of other charges involving alleged corruption and embezzlement.

Yunus’ supporters believe he’s being harassed because of frosty relations with Prime Minister Sheikh Hasina. Bangladesh’s government has denied the allegation.

Monday’s verdict came as Bangladesh prepares for its general election on Jan. 7, amid a boycott by the country’s main opposition party, the Bangladesh Nationalist Party, led by former Prime Minister Khaleda Zia, Hasina’s arch-enemy. The party said it didn’t have any confidence the premier’s administration would hold a free and fair election.

In August, more than 170 global leaders and Nobel laureates in an open letter urged Hasina to suspend all legal proceedings against Yunus.

The leaders, including former U.S. President Barack Obama, former U.N. Secretary-General Ban Ki-moon and more than 100 Nobel laureates, said in the letter that they were deeply concerned by recent threats to democracy and human rights in Bangladesh.

Hasina responded sharply and said she would welcome international experts and lawyers to come to Bangladesh to assess the legal proceedings and examine documents involving the charges against Yunus.

In 1983, Yunus founded Grameen Bank, which gives small loans to entrepreneurs who would not normally qualify for bank loans. The bank’s success in lifting people out of poverty led to similar microfinancing efforts in other countries.

Hasina’s administration began a series of investigations of Yunus after coming to power in 2008. She became enraged when Yunus announced he would form a political party in 2007 when a military-backed government ran the country and she was in prison, although he did not follow through on the plan.

Yunus had earlier criticized politicians in the country, saying they are only interested in money. Hasina called him a “bloodsucker” and accused him of using force and other means to recover loans from poor rural women as head of Grameen Bank.

In 2011, Hasina’s administration began a review of the bank’s activities. Yunus was fired as managing director for allegedly violating government retirement regulations. He was put on trial in 2013 on charges of receiving money without government permission, including his Nobel Prize award and royalties from a book.
