See this explained in the Mark 12:13-27 notes.
The priests and rulers had listened in silence to Christ's pointed rebukes. They could not refute His charges. But they were only the more determined to entrap Him, and with this object they sent to Him spies, “which should feign themselves just men, that they might take hold of His words, that so they might deliver Him unto the power and authority of the governor.” They did not send the old Pharisees whom Jesus had often met, but young men, who were ardent and zealous, and whom, they thought, Christ did not know. These were accompanied by certain of the Herodians, who were to hear Christ's words, that they might testify against Him at His trial. The Pharisees and Herodians had been bitter enemies, but they were now one in enmity to Christ. DA 601.1Read in context »
But there was something in the prisoner that held Pilate back from this. He dared not do it. He read the purposes of the priests. He remembered how, not long before, Jesus had raised Lazarus, a man that had been dead four days; and he determined to know, before signing the sentence of condemnation, what were the charges against Him, and whether they could be proved.

If your judgment is sufficient, he said, why bring the prisoner to me? “Take ye Him, and judge Him according to your law.” Thus pressed, the priests said that they had already passed sentence upon Him, but that they must have Pilate's sentence to render their condemnation valid. What is your sentence? Pilate asked. The death sentence, they answered; but it is not lawful for us to put any man to death. They asked Pilate to take their word as to Christ's guilt, and enforce their sentence. They would take the responsibility of the result. DA 725.2
Pilate was not a just or a conscientious judge; but weak though he was in moral power, he refused to grant this request. He would not condemn Jesus until a charge had been brought against Him. DA 725.3Read in context »
