הלכות עדות

Lying witnesses are neither executed, given lashes, or required to make financial restitution unless both of them were fit to serve as witnesses and they were both disqualified through hazamah after the judgment was rendered.
If, however, only one of them was disqualified through hazamah, they were both disqualified through hazamah before the judgment was rendered, or after the judgment was rendered, one of them was disqualified because of family connections or because he was unfit to serve as a witness, the witnesses are not punished, even though they are disqualified through hazamah and no longer acceptable to deliver testimony in all matters of Scriptural Law.

Although according to Talmudic logic one might differ, if the person against whom they testified was executed and then they were disqualified through hazamah, they are not executed. This is derived from Deuteronomy 19:19: which speaks of: 'what they conspired to do.' Implied is that it was not already done. This rule is part of the Oral Tradition.
If, however, the person against whom they testified was lashed, they are lashed. Similarly, if money was expropriated from one person and given to another, it is returned to its owner and the witnesses are required to pay the penalty.

The following laws apply if there were three or even 100 witnesses. If the witnesses deliver testimony in court one after the other, each one testifying immediately after his colleague and several of them were disqualified through hazamah, they do not receive punishment until all of them are disqualified through hazamah.
If, however, the interval between testimonies was greater than the time it takes a student to greet a teacher, the testimonies are divided and the two who were disqualified through hazamah are punished. The two who testified after there was such an interlude between their testimony and that of the first pair are not punished. This applies even though the entire testimony is disqualified because all of the witnesses are considered as one group and when the testimony of part of a group is disqualified, the entire testimony is disqualified.

When one witness delivers testimony, that testimony is investigated, and the second witness states: 'I also testify like him,' 'Yes, this is what happened,' or the like, they are both executed, lashed, or subjected to a financial penalty if they are both disqualified through hazamah. The rationale is that any witness who says 'Yes, this is what happened' after his colleague testified is considered as having testified and responded to cross-examination as his colleague did.
There is no concept of inadvertent transgression with regard to lying witnesses, because the transgression does not involve a deed. Therefore there is no need for a warning as we explained.

Just as two witnesses can disqualify 100 witnesses through hazamah if the 100 testify at one time; so, too, they can disqualify them through hazamah if they testify as 50 groups, coming two by two.
What is implied? A group of witnesses testified that Reuven killed Shimon in Jerusalem. Two witnesses came and disqualified that group through hazamah. Another group came and delivered that same testimony, that Reuven killed Shimon in Jerusalem and these same two witnesses arose and disqualified that group through hazamah. This happened a third time and a fourth time. Even if it happens 100 times, all the other witnesses are executed on the basis of the testimony of these two.

When one group of witnesses testify that Reuven killed Shimon in Jerusalem and a second group come and disqualify the first group through hazamah, the lying witnesses should be executed and Reuven's life saved. If a third group come and disqualify the second group through hazamah, the second group and Reuven should be executed and the lives of the first group saved.
If a fourth group come and disqualify the third group through hazamah, the third and the first groups should be executed and the lives of Reuven and the second group saved. Similarly, even if there are 100 groups, each one disqualifying the testimony of the previous through hazamah, one group's testimony is accepted and the other group's testimony is disqualified.

When witnesses testify that a person who is trefe murdered a person and then the witnesses are disqualified through hazamah, the witnesses are not executed. The rationale is that even if they had killed him with their hands, they would not be executed, because he is trefe.
Similarly, if witnesses who were trefe testified concerning a matter punishable by execution by the court and were disqualified through hazamah, they are not executed. The rationale is that if their testimony was disqualified through hazamah, and the testimony of the witnesses who testified against them was disqualified through hazamah, those witnesses would not be executed, for they disqualified only a person who was trefe.

The following rule applies when witnesses testify against another person and have him convicted in a matter that does not involve lashes, capital punishment, or a financial obligation and then the witnesses are disqualified through hazamah. They are given lashes even though they did not conspire to have the defendant lashed or to obligate him financially.
What is implied? Witnesses testified that a priest was a challal, e.g., they testified that his mother was divorced or released through chalitzah in their presence in this-and-this place on this-and-this date. If the witnesses are disqualified through hazamah, they are punished by lashing.
Similarly, if they testified that a person inadvertently killed a colleague and they are disqualified through hazamah, they are punished by lashing; they are not exiled. And if they testify that a person's ox killed another person and they were disqualified through hazamah, they receive lashes and are not required to pay an atonement fine. If they testify that a person was sold as a Hebrew servant and they were disqualified through hazamah, they receive lashes. These four rulings are part of the Oral Tradition.

With regard to the above matters, our Sages received the following tradition: When two people cause a righteous person to be condemned and a wicked person to be vindicated through their testimony and two others come and disqualify their testimony through hazamah vindicating the righteous person and condemning the wicked, the first pair of witnesses receive lashes even though their condemnation of the righteous person would not have had him subjected to lashes.
If, however, witnesses testify that a person partook of milk and meat or wore shaatnez, they are punished by lashes, as implied by Deuteronomy 19:19: 'You shall requite him as he conspired.'

When two witnesses testify that Reuven committed adultery with the daughter of a priest, Reuven was sentenced to death by strangulation and the daughter of the priest was sentenced to be burnt to death, and afterwards the witnesses were disqualified through hazamah, they should be executed by strangulation and not burnt to death. This is part of the Oral Tradition.
