Albert Barnes Commentary John 18:14

"Now Caiaphas was he that gave counsel to the Jews, that it was expedient that one man should die for the people." — John 18:14 (ASV)

Which gave counsel, etc. (John 11:49–50). This is referred to him, probably, to show how little prospect there was that Jesus would have justice done to him in the hands of a man who had already pronounced on the case.
