Wasant said the Friday’s inquiry session was slightly delayed because the panel had to review the status of three justices, including himself.
He said the three wanted to exit the inquiry due to concerns about prejudiced decisions, as they had given interviews about the case.
On Thursday, justice Jaran Pakditanakul sought and received the permission to withdraw from the inquiry on grounds that his past remarks had revealed his thoughts on how he would form a decision.
Eight justices still remain on the inquiry panel.
