[6] Sinha is known for a number of high-profile judgments including those on the killing of former President Sheikh Mujibur Rahman and the 5th and 13th amendments to the Constitution of Bangladesh.
[4] The 16th amendment of the constitution of Bangladesh was passed by the parliament on 17 September 2014 which would give power to Jatiya Sangsad to remove judges if allegations of incapability or misconduct against them are proved.
[11] The Jatiya Sangsad on September 13 passed a resolution calling for legal steps to nullify the Supreme Court verdict.
[15] On 14 October, a day after Sinha left the country, the Supreme Court released a statement[11] citing 11 charges against him including money laundering, financial irregularities, corruption and moral turpitude.
[16] According to the statement, on 30 September, President Mohammad Abdul Hamid handed over documentary evidence over those allegations to four other appellate division justices.
[18] On 10 July 2019, the Anti-Corruption Commission sued Sinha and 10 others on the charge of misappropriating and laundering about Tk 4 crore from the Farmers Bank in 2016.
[19][20] A day later, Sinha rejected the allegations against him but said he would not defend himself in court, he had committed no wrong and that Sheikh Hasina’s government had been misusing the law.
[21] According to a Canadian online news portal, The Star, Sinha crossed into Canada through Fort Erie from the United States on 4 July and filed a refugee claim.
Sinha claimed that Hasina, using DGFI personnel, forced him to leave the country due to his efforts to uphold judicial independence despite her interference.
He noted that tensions began when he initiated measures to prevent lower courts from granting bail to notorious criminals shortly after his appointment as the 21st Chief Justice of Bangladesh in January 2015.
The situation further intensified when he refused to rule in favor of the government in the 16th amendment case, which concerned the removal of Supreme Court judges, in July 2017.
"I could figure that the prime minister perhaps convinced the other judges of the apex court bench to deliver judgement in favour of the government.
Sinha stated that after all seven judges of the Appellate Division unanimously delivered the verdict on July 3, 2017, which scrapped the 16th amendment, members of the ruling party, including Prime Minister Hasina, harshly criticized him for over five hours.
Sinha added an incident where, after a day at the Supreme Court, the DGFI chief visited his office, claiming that the prime minister had sent him to demand his resignation and departure from the country.
When he arrived home that evening, he found his residence completely secured by military personnel in plainclothes, with all gates closed and internet connections disconnected.
The following morning, as he worked from his residential office, Justice Md Abdul Wahhab Miah called, requesting to meet him.
When they arrived, they informed him they would not sit with him in court, a decision Sinha recognized as being influenced by the government, further isolating him and undermining his position.
