The former chairman of the Pakistan Cricket Board (PCB) said on Tuesday that Australian umpire Darrell Hair had still not been forgiven for his role in August's forfeited Oval Test against England.
Shaharyar Khan, who resigned last week over the furore, said his replacement as chairman, Nasim Ashraf, would continue to press the International Cricket Council (ICC) to launch an inquiry into Hair's role in the debacle.
"It's a wrong impression that we have forgiven Hair. Instead, our lawyer has prepared a paper and the new chairman has also vowed to further the case," Khan told AFP.
At the Oval Test, Hair and fellow umpire West Indian Billy Doctrove, accused Pakistan of tampering illegally with the ball.
This led to the Pakistan team's refusal to continue the Test which umpires later awarded to England on forfeit - the first time this had happened in Test cricket's 129-year history.
An ICC disciplinary hearing acquitted Pakistan captain Inzamam-ul Haq of the ball-tampering charges but banned him for four one-day matches for bringing the game into disrepute by leading his team in protest.
