Mark 15:3

‘And the chief priests accused him of many things.'

The Chief Priests, after at first prevaricating, listed their charges. Luke 23:2 gives examples. ‘Perverting the nation', ‘forbidding the giving of tribute to Caesar', ‘calling Himself the Messiah, a king'. All this had nothing to do with the main charge that they had against Him, that of blasphemy, but they were aware that that would not have impressed Pilate. However, these charges did not impress Pilate either. What did impress him was the silence of the prisoner in the face of His accusers. It was clear that Jesus wanted nothing to do with them or their accusations, and simply saw Himself as unaffected by all that they said. Pilate was used to the defiance or pleading of defendants, but not to such dignified silence.

We should not that ‘many things' indicates quite a period of time. The charges had to be put, dressed up in revolutionary terms, and evidence sought. And then Jesus had to be questioned about them. This latter, however, did not take much time as He did not deign to even respond to their obviously unreasonable charges.
