The Indian mission has already taken up the issue strongly with the Pakistani authorities.
All 12 passengers carried negative Polymerase Chain Reaction COVID-19 reports but they were re-tested in line with the laid down COVID-19 safety protocols in Pakistan.
Foreign Office spokesman Zahid Hafeez Chaudhri said on Thursday that "there was no pressure on Pakistan at all regarding the release of Wing Commander Abhinandan."
"The Indian side has been also making incongruous demands of allowing an Indian lawyer to represent Commander Jadhav. "We have repeatedly told them only those lawyers can represent Commander Jadhav in the court who have a licence to practise law in Pakistan. This is in accordance with legal practice in other jurisdictions also," Pakistan Foreign Office spokesman Zahid Hafeez Chaudhri said.
India and Pakistan in a surprise announcement said on February 25 that they have agreed to strictly observe all agreements on ceasefire along the Line of Control in Jammu and Kashmir and other sectors.
Jadhav, the 50-year-old retired Indian Navy officer, was sentenced to death by a Pakistani military court on charges of 'espionage and terrorism' in April 2017. Weeks later, India approached the ICJ against Pakistan for denial of consular access to Jadhav and challenging the death sentence.
