No verdict or indictment shall be void or voidable because any juror shall fail to possess any of the qualifications required in this act unless a juror shall knowingly answer falsely any question on voir dire relating to his qualifications propounded by the court or counsel in any cause. A juror who shall knowingly fail to respond audibly or otherwise as is required by the circumstances to make his position known to the court or counsel in response to any question propounded by the court or counsel, the answer to which would reveal a disqualification on the part of the juror, shall be deemed to have answered falsely.
