In the Synoptics, Jesus is taken to the Sanhedrin, with Matthew adding that the Sanhedrin had assembled where Caiaphas was located, possibly implying that the gathering occurred at the home of Caiaphas.
At the time in which the narrative is set, this body was an ad hoc gathering, rather than a fixed court (Brown 146), as in the latter Council of Jamnia, and its gathering in Caiaphas' home is historically plausible, though irregular. Daniel J. Harrington argues that being located in a home makes it more likely that this was a small first preliminary hearing and not a full trial. According to Rabbinic Judaism, the Sanhedrin of the Pharisees, probably a different sanhedrin, was led by Gamaliel from approximately the year 9 to 50. This is believed to be the same Gamaliel who appears in Acts 5:34 and 22:3. Shammai may have also played a role.
