During his recent four-day visit to the US, Sharif committed to task his top law officials with reviewing the prosecution process for Dr Shakil Afridi, the Fox News reported, quoting those who attended the impromptu meeting.
The assurances from Sharif came during his visit here last week at a carefully stage-managed private meeting that took place between the Pakistan Prime Minister, Congressional representatives and a non-government individual.
Chairman of the House Committee on Foreign Affairs Representative Ed Royce together with Robert Lorsch of the Free Afridi Campaign heavily pressured the Pakistani leadership about releasing the doctor and allowing him a life in the US, it said.
"My message to them was: 'What they do with Dr Afridi is how Pakistan will be judged as a democracy by the rest of the world,'" Lorsch told Fox News in an interview.
The meeting lasted around 25 minutes in a side-room immediately prior to dinner hosted by the House Committee on Foreign Affairs, it said.
"This was first time that the leadership in Pakistan realised the importance of Dr Afridi not as a political bargaining tool but as a symbol of how freedom-loving American people regard Pakistan," Lorsch was quoted as saying.
"They prosecuted the man who brought the mastermind of 9/11 to justice," he added.
Afridi was arrested shortly after the May 2, 2011, raid by US commandos that killed bin Laden. He was subsequently convicted by a court in the tribal belt on a charge of treason for alleged ties to the Lashkar-e-Islam militant group.
On August 29, a judicial official overturned the 33-year jail term given to Afridi and ruled that the judge in the tribal areas had exceeded his authority when he handed down the sentence last year. The official also ordered a fresh trial.
