According to Israeli law, the Knesset House Committee is to discuss his request and should it be approved, the request will need to pass a vote by the Knesset plenum.
However, since the House Committee has not been appointed since the April general election, and is not expected to be assembled before the upcoming March election, the discussion will only take place in several months. Until the committee makes a decision, an indictment against Netanyahu can‘t be handed officially to the court.
