According to a press release on David Irving's website he is planning to sue the organizers of the annual Warsaw International Book Fair, for damages for breach of contract, after he was ejected from the fair.
Some email communiques I have received have taken the tone: "He just will never learn." In other words, everytime he goes into court or toys with the legal system,e.g. his Novermber 2005 trip to Austria even though there was an outstanding warrant against him, he loses big time.
My perspective is different. This is the only way for him to get the publicity which he seems to me to so desperately crave.
