[Linux-aus] Legal Eagle question

[David Cartwright]

Computerworld quotes Red Hat's Mark Webbink stating that SCO "retained David
Boies' law firm (of Microsoft antitrust fame) on a contingency basis, by
their own admission."

I have a question for any 'legal eagles':
Assuming a law firm accepts a case on a contingency basis, but it is
subsequently shown that the client has deliberately, or through lack of due
diligence, mis-represented the case, could the law firm sue their former
client?
