If the ball while in play in In-goal at either end,
but not held by a player, touches the referee, a
touch judge, or a spectator, a try shall be awarded
at that place provided an attacking player would
otherwise have scored it.
(iii) When the ball touches a spectator in either of
the above cases, if the referee is in doubt, the
award shall be made to the visiting team if that
team is the defending team under (i)
or the
attacking team under (ii).
