Any employee of a commission who in such affidavit intentionally makes a false statement of material fact or intentionally fails to disclose any information necessary to make any statement of material fact made therein not misleading shall be guilty of perjury and shall be subject to prosecution and punishment therefor in the same manner as if he had committed perjury as a witness in open court.
