In a dramatic session yesterday, the former New Zealand allrounder left his seat next to his wife Melanie Croser at the front of the court and walked to the public gallery at the back where Modi was sitting at the end of a row.
He gestured in his direction from the other side, before one of his three lawyers intervened and motioned him outside.
Earlier, the court heard from former South African player Andrew Hall, who succeeded Cairns as captain of the Lions. He had been worried what would happen to him.
In his witness statement, Hall said that after Cairns' dismissal, the Kiwi told him and the team's strength and conditioning coach, Jock Campbell, that he had been "made a scapegoat".
Hall said he confronted some of the local players in the team, saying he would not put up with them trying to "destroy" him too.
Counsel for Cairns, Andrew Caldecott, QC, asked Hall: "Did it ever cross your mind that Cairns was being set up?"
Hall replied: "Yes."
