Gavaskar, Chairman of ICC's Cricket Committee and who was also a part of a review committee on chucking laws, said no bowler is ever cleared for good and is open to scrutiny at any time.
"Shoaib Akhtar could be called up again for his action," the former captain said during a discussion in Sportscentre, ESPN-Star Sports news programme.
"There is one thing that everyone needs to understand that no bowler is ever cleared. Every ball he bowls can be scrutinised and he can be called. The umpire out on the field can call the bowler if he feels that his action is not right," he said.
Shoaib, who was cleared by ICC after being reported thrice for chucking, has once again come under the scanner with some former cricketers and India coach Greg Chappell hinting that his action was questionable.
The fastest bowler in the world is currently playing in the home series against India.
Gavaskar said although umpires refrain from calling the bowler themselves, they often do report their doubts to the third umpire or the match-referee.
"Unfortunately, because sometimes there is an optical illusion that is created, lot of umpires prefer to report to third umpire and the match referee. And therefore the bowler can come under the scanner of ICC," Gavaskar said, according to excerpts of the programme made available to PTI.
In the same vein, the former Indian captain appreciated Sri Lankan spinner Muttiah Muralitharan for responding to Australians' doubts by getting tested Down Under.
"But what Murali is doing, because he has had problems with Australian crowds and odd reports in the media over there, he has just gone to give himself the confidence as well as his supporters and the crowds that look I am going to your guys, I am going to undertake tests at your labs. And therefore he is just trying to clear his name and which I think is fantastic."
