"We are surprised at this development and will challenge his absence when the hearing proceedings begin," said Kaneria, who was banned for life by the England and Wales Cricket Board (ECB) in June for corruption.
Kaneria will appeal against the ban this week after being branded a "grave danger" to the game by the ECB who found him guilty of encouraging or attempting to encourage Westfield to underperform in a match in 2009.
The Pakistani leg-spinner, who has been suspended by the Pakistan Cricket Board (PCB) pending the outcome of the appeal hearing, said he wanted Westfield to appear before the five-man ECB panel.
