The 275th prohibition is that a judge is forbidden from favoring one of the litigants during a trial. Even if he is very important and distinguished, he shall not accord him any honor when he comes to court with the other litigant, and not show him any special respect.
The source of this prohibition is G‑d's statement1 (exalted be He), "Do not show respect to the great."
The Sifra2 says, "One should not think, 'He is wealthy and from a distinguished family — how can I embarrass him and witness his shame?' Certainly [one who thinks this way] will not shame him. The Torah therefore says, 'Do not show respect to the great.' "
The details of this mitzvah are explained in many passages in tractates Sanhedrin and Shavuos.3
