From the Passion narrative according to John (John 18)

29 So Pilate came out to them and asked, “What charges are you bringing against this man?”

30 “If he were not a criminal,” they replied, “we would not have handed him over to you.”

31 Pilate said, “Take him yourselves and judge him by your own law.”

“But we have no right to execute anyone,” they objected.

Literally the exact same method that the Jewish religious authorities used to try to convince the Romans to execute Jesus because they weren’t allowed to execute people.

(Note: this is not meant to be antisemitic, just contextual, though the Jews’ role in the execution of Jesus has been and is still used to justify antisemitism)
