When all the judges of a Sanhedrin begin their judgment of a case involving capital punishment and say that the defendant is liable, he is exonerated. There must be some who seek to exonerate him and argue on his behalf, but yet the majority hold him liable. Only then he is executed.
🔄 Paradox of Unanimity
In capital cases, if all judges vote liable, the defendant is exonerated. There must be at least some who argue for exoneration — a unanimous guilty verdict reflects a flawed process, not justice.
The following rules apply when there is a difference of opinion in a minor Sanhedrin. If twelve judges say that he should be exonerated and eleven say that he should be held liable, he is exonerated. If twelve say that he is liable and eleven say that he should be exonerated or eleven say that he should be exonerated and eleven say that he is liable, and one says: "I don't know," we add two judges. Even if there are twelve who wish to exonerate him and twelve who hold him liable, and one who one says: "I don't know," we add two judges. The rationale is that the judge who says: "I don't know," is considered as if he does not exist, for he cannot change his mind and explain why the defendant should be held liable. Thus after the addition, there are 24 judges aside from the person who says: "I don't know." If twelve say that he should be exonerated and twelve say that he is liable, he is exonerated. If eleven say that he should be exonerated and thirteen say that he is liable, he is liable. This applies even if one of the original judges says: "I don't know." For there are two more judges who rule that he is liable. If twelve say that he should be exonerated and twelve say that he is liable, we add two judges. And similarly, if the balance is not broken, we continue to add two judges until there is at least one more judge who rules that he should be exonerated or at least two more judges who rule that he should be held liable. If there are an even number of judges on both sides, and one says: "I don't know," or if the number of judges who rule that he is liable is only one more than those who rule that he should be exonerated, we continue to add judges until we reach 71. The following rules apply when the court reaches that size. If 36 say that he should be exonerated and 35 say that he is liable, he should be exonerated. If 36 say that he is liable and 35 say that he should be exonerated, they debate back and forth against each other until one of them sees the other's perspective and either exonerates him or holds him liable. If such a change in perspective does not take place, the judge of the greatest stature declares: "This judgment has become aged," and he is released. If 35 say that he is liable and 35 say that he should be exonerated, and one says "I don't know," we release him. If 34 say that he should be exonerated and 36 say that he is liable, and one says: "I don't know," he is held liable. For there is a majority of two judges who hold him liable.
⚖️ 23-Judge Rules
In a minor Sanhedrin of 23: a majority of 12 to 11 exonerates; a majority of 13 to 10 convicts. A 12-to-11 majority for liability requires adding 2 judges at a time — up to 71 — until resolution.
When there is a difference of opinion in the Supreme Sanhedrin, whether with regard to a law involving capital punishment, monetary law, or other matters of Torah law, we do not add judges. Instead, they debate against each other and the ruling follows the majority. If their difference of opinion involves whether a person will be executed, they should debate against each other until they either exonerate him or hold him liable.
🏛️ 71 Decides All
When the Supreme Sanhedrin of 71 reaches a split decision on any matter — capital, monetary, or Torah law — they do not add judges. They debate until a majority of the 71 is reached. The majority rules.

The Defendant's Safeguard Against Unanimity The requirement that at least one judge argue for exoneration in capital cases is a profound protection against mob mentality and groupthink. If nobody advocates for the defendant, the system itself has failed him.
📏
Asymmetric Majority Requirements Capital cases require more than a bare majority to convict (13 of 23), but only a bare majority to exonerate (12 of 23). This asymmetry expresses the principle that we err on the side of life.
🔢
Expanding the Court to Break Deadlock When a minor Sanhedrin of 23 deadlocks at 12-12, it expands by two judges at a time — potentially reaching the full 71. This exhaustive process reflects how seriously halacha takes capital decisions.

The Supreme Sanhedrin as Final Authority The Great Sanhedrin of 71 is the court of last resort for all matters — capital, monetary, and matters of Torah law. Its majority opinion is binding with no mechanism for further appeal or expansion.
