What makes you think that? Not true. And it wouldn't be illegal if you did, either.
The fact of the matter is, the unemployment officials are well aware of the fact that in an unemployment hearing, either the employer or the employee, or both of them, may be lying. That's just a fact of life to them and they take it in stride.
Besides which, I don't think we've established absolutely that anyone lied. It's not outside the realm of possibility that someone made an error, but there's a difference between deliberately lying and making a mistake.
