Pakistan have called on the International Cricket Council (ICC [Images]) to introduce neutral umpires for one-day internationals.

In a letter written to ICC chief executive Malcolm Speed [Images], the Pakistan cricket board (PCB) has also asked for a review of all umpiring decisions in the one-day series in Australia.

PCB director of media Abbas Zaidi confirmed a letter had been sent to the ICC on the subject of umpiring but was not willing to reveal the contents.

"It is a confidential document and we would not like to discuss it in public," Zaidi said on Sunday.

Sources close to the board said Pakistan felt the umpiring in the triangular series, which also involved West Indies [Images], had been inconsistent and the ICC needed to review some of the decisions given in their games.

"It is not a complaint about the umpiring. But the Pakistan board has suggested that, like in Test matches, neutral umpires should now supervise the ODIs," one source said.

"Another suggestion is that umpires should make more use of the modern technology available to them while ruling on contentious caught behind or leg before decisions," he added.

The ICC introduced an elite panel of umpires, who officiate almost all Test matches, in 2002.

For one-day internationals, one neutral umpire and one from the host country are appointed.
