3. Any person preferring a charge of malfeasance against a juror sitting in the case at bar, which charge he is unable to substantiate, and the hearing being one at the conclusion of which the death penalty may be adjudged, the person so preferring such charge shall be put to death.
This statement is outlining a rule or provision related to a legal case where a person accuses a juror of wrongdoing (specifically, malfeasance, meaning improper or illegal behavior). According to this statement, if someone makes such an accusation against a juror but is unable to provide evidence or prove it, and if the case being heard by the jury may result in the death penalty, then the person making the false accusation will face the death penalty themselves. In simpler terms, it means that if someone falsely accuses a juror without evidence in a serious case, they themselves will be punished with death.
