What are the differences between cases involving financial matters and cases involving capital punishment? Cases involving financial matters are adjudicated by three judges, while cases involving capital punishment are adjudicated by 23. In cases involving financial matters, we begin the judgment either with a statement to the defendant's detriment or his advancement, while with regard to cases involving capital punishment, we begin with a statement which points towards acquittal, as we explained, and we don't begin with one which points toward his conviction.
In cases involving financial matters, we make a decision based on a majority of one whether it is to the defendant's detriment or in his support, while with regard to cases involving capital punishment, we acquit him on the basis of a majority of one, but convict him only when there is a majority of two. In cases involving financial matters, we retry a judgment whether doing so is to the defendant's detriment or his advancement, while with regard to cases involving capital punishment, we retry a judgment if it will lead to acquittal, but not if it will lead to conviction, as we explained.
In cases involving financial matters, everyone - both the judges or the scholars - is entitled to advance any rationale whether it is to the defendant's detriment or in his support. With regard to cases involving capital punishment, by contrast, everyone - even the students - may advance a rationale leading to acquittal, but only the judges may advance a rationale leading to conviction. In cases involving financial matters, a person who advanced a rationale to the defendant's detriment may change his mind and advance a rationale in his support. Conversely, one who advanced a rationale in the defendant's support may change his mind and advance a rationale to his detriment. With regard to cases involving capital punishment, by contrast, a judge who advanced a rationale for conviction may advance a rationale for acquittal, but a judge who advanced a rationale for acquittal may not change his mind and advance a rationale for conviction. At the time the judgment is being rendered, however, he may vote to be counted among those favoring conviction, as we explained.
Cases involving financial matters are adjudicated during the day, but the verdict may be rendered at night. Cases involving capital punishment are adjudicated during the day and the verdict must also be rendered during the day. The verdict in cases involving financial matters is rendered on that very day, whether it is to the defendant's detriment or in his support. With regard to cases involving capital punishment, by contrast, a verdict of acquittal is rendered on that very day, but a verdict of conviction is not rendered until the following day.

For this reason, we do not adjudicate cases involving capital punishment on Fridays, nor on the days preceding festivals. The rationale is that the defendant may be convicted and it is impossible to execute him on the following day, but it is forbidden to postpone his execution until after the Sabbath. Hence, we imprison him and begin his trial on Sunday.

All of the same laws that apply to cases involving capital punishment apply also to cases involving lashes and exile, except that cases involving lashes are adjudicated by three judges. None of these distinctions are made with regard to the judgment of an ox that is stoned except for one, that the judgment is adjudicated by 23 judges.

The laws which pertain to a mesit, a person who entices others to serve false divinities, differ from those pertaining to others liable for capital punishment. We hide witnesses to observe his act. He does not need a warning as must be given to others who are executed. If he departed from the court after being acquitted, and someone said: "I know a rationale that will lead to his conviction," he is returned and retried. If he was sentenced to death and someone said: "I know a rationale that will lead to his release," he is not retried. The court does not advance arguments in defense of a mesit. An elderly person, a eunuch, and a person who does not have sons are placed on the court which judges him, so that they will not have mercy on him. For cruelty to those who sway the people after emptiness brings mercy to the world, as implied by Deuteronomy 13:19: "so that God will turn away from His fierce anger and grant you mercy."

With regard to cases involving monetary matters and similarly questions of ritual purity and impurity, the judge of the greatest stature gives his ruling first and the other judges hear his ruling. With regard to laws involving capital punishment, we begin from the side. The words of the judge of the highest stature are not heard until the end.

With regard to cases involving monetary matters and similarly questions of ritual purity and impurity, a father and his son and a teacher and his student are counted as two judges. With regard to cases involving capital punishment, lashes, and the sanctification of the moon and the declaration of a leap year, a father and his son and a teacher and his student are counted as one.

The concept that a father and a son are counted as one or as two applies when one is a member of the Sanhedrin and the other was one of the students attending the court who said: "I can contribute a rationale that will lead to his vindication," or "...to his being held liable." We listen to his words and enable him to participate in the debate, and he is counted in the polling of the judges.

When a student was wise and understanding but is lacking sufficient knowledge of the tradition, his master may convey to him the tradition which he requires with regard to these laws and then he may serve as a judge even in cases regarding capital punishment.

All individuals are acceptable to judge cases involving financial laws, even a convert, provided his mother is a native-born Jewess.
A convert may judge a fellow convert even if his mother is not a native-born Jewess. Similarly, a mamzer and a person who is blind in one eye are acceptable to adjudicate financial disputes. Cases involving capital punishment, however, may be judged only by priests, Levites, and Israelites with lineage acceptable to marry into the priesthood. not one of them may be blind even in one of his eyes, as we explained.
