Last year Mr Khandakar posted comments implying that he wanted Sheikh Hasina to die, high court officials said. His comment reportedly related to Bangladesh's high road fatality rate.
It was posted following the death of one of the country's best known film makers, Tareq Masud, in a road accident in August, which left many Bangladeshis deeply shocked. According to officials, Ruhul Khandakar blamed the government for the fact there are so many road deaths in Bangladesh.
The high court ordered officials to return Mr Khandakar, who is studying in Australia, to Bangladesh. It also directed his university employers to take action against him.
