The ICC has rejected PCB's claim that the decision to move 2011 WC matches from Pakistan was legally flawed, saying they had not removed the country as a co-host of the event, but only relocated the ties assigned to them.
ICC Chief Executive Haroon Lorgat rued that Pakistan decided to take the legal course to resolve the matter and hoped it would "withdraw its spurious claims".
"We are naturally disappointed that the PCB has chosen to pursue its grievance with the ICC through legal channels but, having received correspondence from its lawyers, we have now responded," Lorgat said in a statement.
"We used our response to clarify inaccuracies and misunderstandings in the PCB's claim. We also pointed out that the ICC Board agreed only that WC 2011 matches should be moved away from Pakistan, not that the PCB should be removed from its position as a joint host of the event itself," he said.
Lorgat made it clear that game's world governing body had the power to shift the location of ties in the best interest of its members who grow on revenue from ICC tournaments.
"The suggestion the ICC Board was not empowered to decide that matches should be moved away from Pakistan and that such a decision was 'legally flawed' is also incorrect and without foundation. The ICC Board is the policy-making body for international cricket and has broad powers under its constitution," he said.
ICC chief executive Haroon Lorgat asked the organizers of the World Cup on Feb 17 in New Delhi to consider alternate venues within their countries "as well as alternate country venues if things are not favorable in one of the particular host countries."
Meanwhile, the ICC has rejected PCB claims that the stripping of 2011 hosting rights was illegitimate because it was not on the agenda of the board meeting in Dubai last month.
"The issue of Pakistan's removal as a host location was on the ICC Board's agenda and in the board papers (and the) board has the power to make such decisions," Lorgat said.
The ICC says the PCB has not taken up an offer by the ICC to form a task force to help keep cricket on its feet in Pakistan during what looks set to be a lengthy isolation from hosting international cricket.
"That offer was made at the ICC board meeting in Perth in January-February but, to date, there has been no response from the PCB," the spokesman said.
Pakistan's removal as a 2011 host was prompted by a militant attack on the Sri Lanka team and its security detail while traveling to a test in Lahore in March.
