The Allahabad High Court on 8th March 2020 maintained its order on the petition challenging the state government's move to put up the poster of people asked to pay compensation for damage to public assets during the anti-CAA protest. The division bench comprised of Hon'ble Chief Justice Govind Mathur and Justice Ramesh Sinha. In Lucknow, about 53 people identified by the police as alleged rioters and was served notice. The Chief Justice Govind Mathur took suo motu cognizance of the hoardings and directed the Lucknow police commissioner Sujit Pandey and district magistrate Abhishek Prakash to appear in the court. Along with that, he also directed them to explain the law under which the hoardings of 53 anti-CAA protesters were erected at the major intersections in the state capital. The division bench of Allahabad High Court comprising of Chief Justice Govind Mathur and Justice Ramesh Sinha took up the matter suo motu concerning the hoardings and banners which unveiled the pictures and individual details of the protesters of CAA-NRC who also destroyed the public properties during the protests. However, on 9th March 2020, the bench directed the Uttar Pradesh police to withdraw the hoardings that display the pictures and individual details of the protestors of CAA-NRC who damaged the public properties throughout the protests. The Bench also ordered the District Magistrate of Lucknow to present a brief on the steps taken by 16th March 2020.

Many people criticized the ruling on social media handles such as Facebook, WhatsApp, and Twitter. The complainant stated some of the hash tags used in social media platforms as 'Justitudes' 'wahReCourt' 'BehaveJustitudes' etc. On which one, Mr. Nutan Thakur registered an F.I.R. at Gomati Nagar Police Station, Lucknow under, Section 66 of the Information Technology Act against the unknown persons who were making offensive and defamatory comments on Justices on social media.  The complaint has also asserted that two persons in social media had also accused the judges of the division bench of having a connection with Pakistan and, consequently, they act to promote the protest and riots.

As the pandemic and lockdown move on, The Allahabad High Court delivered an order on 19th March 2020, stating, that 'Don't issue an order to compel people to move court.' This decision came after a person named Darpan Sahu, who filed a petition against a bank recovery in the High Court. The issue raised was the legality of recovery proceedings. The bench comprised of Justice Ramesh Sinha and Justice Ajit Kumar. They stated that due to the threat of coronavirus, no such order should be issued against anyone pushing people to move courts. The court also assures that no such order will be announced from the district or a different level, forcing anyone to seek the shelter of the court. The Allahabad High Court also restricted the government not to initiate any recoveries or coercive actions till 6th of April 2020, to decrease the spread of coronavirus (COVID-19). The division bench ordered certain procedures that will be deferred until the 6th of April 2020.

There was a judgment where The Lucknow High Court turned down the bail plea of former Noida Authority chief engineer Yadav Singh on technical grounds in connection with a money-laundering case filed by the Enforcement Directorate (ED) against him. A bench of Justice Ramesh Sinha and Justice Rekha Dixit passed the order. The Allahabad High Court had directed the CBI, in July 2015, to investigate the case declaring that the allegations were most grave.

Again on another judgment, The Lucknow bench of the Allahabad High Court said Uttar Pradesh Advocate General (AG) Raghvendra Singh had committed contempt of court by not appearing before it, on the pretext of being busy at the meeting throughout the day, despite of the repeated calls sent to him.

A bench of justices Ramesh Sinha and Rekha Dixit stated, "The attitude and conduct of the AG in not obliging before the court and amounts to contempt of the court, despite repeated calls to him by additional government advocates Smriti Sahai and RK Dwivedi.

It added that it had set a bad example for the state council as well as members of the Bar, who were already in the court, and also before the entire legal fraternity.
