The world cricketers' association said on Thursday it "outright rejects" the MCC's proposals to encourage players to take lie detector tests in an effort to fight corruption within the game.
The Marylebone Cricket Club (MCC), the guardian of the rules of cricket, says the potential use of lie detector tests should be widely debated.
Former Australia captain Steve Waugh, an MCC member, this week took a lie-detector test as part of his bid to help root corruption out of cricket.
But the Federation of International Cricketers' Associations (FICA) said the testing was irresponsible and it would oppose such actions in "the strongest possible manner".
"It is FICA's strong position that the use of lie detectors as a means of determining the guilt or innocence of a player in matters relating to corruption on any practice for that matter is to be rejected outright," FICA chief executive Tim May said .
"I commend MCC and Steve Waugh for trying to be proactive in the fight against corruption, but lie detector tests are far from foolproof and not permissible," May added.
"It is therefore totally unacceptable that players should be put under pressure to submit to testing that is far from foolproof. "To publicly request players to make 'some stand' against corruption, by submitting to this 'imperfect' testing is irresponsible and FICA will oppose such actions," May said.
