No one has to challenge their expertise. The burden to establish that they qualify as experts lies with the attorney calling them. The standards by which that burden is met are typically jurisdiction-specific. In this case, Orly made no attempt to establish that her witnesses were experts. Based on past performance, I would suspect that is because she doesn't understand that she has to. In any event, having dealt with this issue numerous times myself, I can say it is unlikely any court would accept the experience of the witnesses proffered as meeting an expert standard.
Really? I don't know precisely what evidence she presented but any court that wouldn't accept someone like Mara Zebest as an expert on Adobe Software needs to be dissolved.
Some things are just obvious when presented too, whether they are presented by someone who has devoted his life to something, or by his secretary. So when the secretary shows enlargements of characters that were all supposed to have been produced by the same typewriter key that obviously were not, it seems absurd to me to reject out of hand what the secretary has shown.
