Can you sue unemployment for "Conspiracy" for allowing a employer to deliberately lie under oath?
Lawsuit / Dispute Attorney
No you would lose your case suing for conspiracy against the Unemployment Office
Employment / Labor Attorney
No. The UC office doesn't "conspire" with the employer to support perjury. Folks fail to tell the truth all the time. Sometimes they get away with it. If you are unhappy with the result, file an appeal. The tribunal is not your opponent. Your prior employer is.
