Cricket Australia "could stand in the way of disgruntled Test cricketers who seek to play in other competitions around the world," according to Greg Baum of THE AGE. CA and the Australian Cricketers' Association "remain at an impasse in their pay dispute," and CA "made it clear" that if there is no agreement by the end of June, the players will "fall out of contract and go unpaid." Test vice-captain David Warner said that he and his teammates "might play instead in lucrative domestic T20 competitions in England, the West Indies or South Africa." Technically, even when uncontracted, they would need "no objection" certificates from CA to play elsewhere. These were introduced by the Int'l Cricket Council in '09 to protect int'l cricket as "the pioneering Indian Premier League began to gather strength and other T20 competitions emerged." To date, CA has not discussed using this device, "hoping for an amicable settlement." The ACA "remains quietly sure it would be unenforceable anyway, as a flagrant restraint of trade." Federation of Int'l Cricketers' Associations Chair Tony Irish said, "We don't believe that players who are uncontracted can be legally restricted in their movement by the regulations and we think that attempts to do this are likely to be open to legal challenge in most countries" (THE AGE, 5/23).
