Halakhah su Deuteronomio 17:12

To listen to the voice of the court at all times: To listen to the voice of the Great Court and to do all that they command us in the paths of the Torah - regarding the forbidden and the permitted, the impure and the pure, the liable and the exempt and in everything that appears to them to be a reinforcement and enhancement to our religion. And about this is it stated (Deuteronomy 17:10), "And you shall act according to the word that they tell you." And it is repeated adjacently (Deuteronomy 17:12) to strengthen the thing, "According to the instruction that they instruct you and to the judgement that they say to you shall you act." And there is no difference in this, whether the thing that they see is from their own intellects or is something that they extracted by one of the comparisons through which the Torah is expounded, or something that they agreed is from the secrets of the Torah or they see that the thing is like this in any other way - in everything, we are obligated to listen to them. And the proof that this is from the tally of positive commandments is their, may their memory be blessed, saying in Sifrei Devarim 154, "'And according to the judgement that they say to you shall you act' - this is a positive commandment."

From the laws of the commandment is that which they, may their memory be blessed, said (Sanhedrin 87a), that even though one who transgresses that which the Sages explained about the words of the Torah, transgresses this negative commandment of "you shall not stray"; nonetheless a man does not have the designation of a rebellious judge - known in the Gemara at the end of Sanhedrin 89a, who is liable for the death penalty - until he disagrees with the Great Court (see Mishneh Torah, Laws of Rebels 3:5, 7), and that he is a sage that has reached [the level] of pronouncing decisions [and] is ordained like the [members of the] Sanhedrin, and that he disagrees with them on a matter the volitional transgression of which [brings] excision and the inadvertent violation of which [brings] a sin-offering, and he instructs to do according to his decision or [himself] does the act according to his decision, as it is stated (Deuteronomy 17:12), "who wantonly does" - and not that he only instructs. But if he is a student that has not reached [the level] of pronouncing decisions, and makes a decision; he is exempt, as it is stated (Deuteronomy 17:8), "If a matter is baffling to you" - one who only a baffling thing is beyond him. And so [too,] if he found them outside of the Compartment of Paved Stone (in the Temple) and he rebelled against them, he is exempt, as it is stated, "and you will arise and go up to the place" - teaching that the place causes (is a requirement for) the death penalty.
