score:7
It's commonly thought to be the (Great) Sanhedrin, Luke certainly implies it to be the same Council that sat in judgment on Jesus:
50 Now there was a man named Joseph, a member of the Council, a good and upright man, 51 who had not consented to their decision and action. He came from the Judean town of Arimathea, and he himself was waiting for the kingdom of God. - Luke 23:50-51 NIV
He earlier describes it as "...the council of the elders of the people, both the chief priests and the teachers of the law..." (Luke 22:66)
