Where in any proceedings other than criminal proceedings the court considers that the evidence of a child is likely to involve matter of an indecent or immoral nature, the court may direct that during the taking of the evidence of that child all or any persons, not being members or officers of the court or parties to the case, their counsel or solicitors, or persons otherwise directly concerned in the case, be excluded from the court.

The powers conferred on a court by paragraph (1) shall be in addition and without prejudice to any other powers of the court to hear proceedings in private or to exclude a witness until his evidence is required.
