JUDGE3
OLSSON J This is an appeal by the State Government Insurance Commission
("SGIC") against
a judgment entered against it in the District Court, on the
issue of third party liability in respect of a claim by the respondent
Wagner
("Wagner") against the State of South Australia ("the State") for damages for
certain personal injuries sustained by him.
2. The relevant facts were never significantly in dispute and may simply be
stated.
3. Wagner was, at all material times, a plant
operator employed by the
Engineering and Water Supply Department ("E and WS"). He normally worked from
the Port Lincoln depot of
the Department. In March 1987 he was engaged in
work involving the laying of sewer mains in the Kirton Point area.
4. On 9 March
1987 Wagner was required to operate a JCB front end loader
equipped with a back hoe ("the plant") in connection with the Kirton Point
project. The plant was owned by E and WS and registered by it as a motor
vehicle. It was mounted on four wheels with rubber tyres
and was normally
driven along the road by its own power, to deploy it to where it was to be
used.
5. Accordingly, having reported
to his supervisor at the depot at about 7.20
am to receive his instructions for the day, he drove his own private vehicle
out to
the worksite. On arrival he picked up the keys to the plant, carried
out certain preliminary checks and maintenance and then started
it and warmed
up the motor.
6. At about 7.40 am Wagner drove the plant, from a location where it had been
parked overnight on a
vacant allotment in Velante Street, a distance of about
200 metres around into Matthew Place. He then positioned it, as required,
at
the site where a trench was about to be excavated. During that journey the
plant was being driven, as a normal motor vehicle,
along public roads.
7. On arrival at the trench site Wagner stopped the plant and went about
preparing it for use in the trench
digging configuration. That involved the
use and operation of the back hoe.
8. I pause at this point to record that the plant,
being multi-functional,
was operated in two quite separate configurations. When the front bucket was
being used for loading, unloading
or moving material, the vehicle was simply
driven on its four wheels as an ordinary motor vehicle, the driver manoeuvring
it by means
of controls operated from the driver's seat as he drove. When so
used it clearly remained a motor vehicle for the purposes of the
Motor
Vehicles Act.
9. However, when it was desired to operate the back hoe in the digging
configuration it was necessary to position
the plant in a fixed position and
stabilize the body of the equipment, as a firm base from which the back hoe
was manoeuvred. This
was normally achieved by lowering the bucket to the
ground at the front, turning the driver's seat 180 (so that it faced to the
rear
of the plant) and then operating controls which lowered two hydraulic
jacks to the ground. When this was done the jacks lifted the
rear wheels of
the plant off the ground, so that, for all practical purposes, the main body
weight or thrust was taken on the two
jacks and the front bucket. When this
configuration was adopted the plant was incapable of being driven along a road
or other surface
as a motor vehicle.
10. On the morning in question Wagner positioned the plant in the desired
location and set it up in the configuration
which I have just described, for
the purpose of operating the back hoe.
11. Having done so he then embarked on the further sequence
of events
necessary actually to put the hoe into motion. This required two, additional,
basic actions on his part.
12. The first
was to release and then raise a rear glass panel (in a metal
frame) from the closed vertical position at the rear of the cabin of
the plant
behind the driver's seat to a position up above his head - rotating it up and
through 90 , so that it snugged up against the roof of the plant cabin,
parallel to
the floor.
13. The second was to lean forward and, whilst jiggling the back hoe controls
to free it, remove a retaining pin which
held the back hoe boom and attached
bucket in a secure, travelling position. This was essentially a safety
device. It was impossible
to remove the pin, or thereafter operate the back
hoe in comfort, without unlatching and raising the rear cabin window.
14. It is
not disputed that, in the course of attempting to open the rear
window of the plant cabin, Wagner experienced a sudden severe pain
in his
lower back. It is accepted that, as a consequence of his physical activity in
attempting to open the rear window, Wagner
in fact sustained incapacitating
bodily injury.
15. As a consequence, he instituted proceedings against the State, as his
employer,
claiming damages in respect of his injury. In essence he asserted
an unsafe system of work and breach of statutory duty. The State
filed a
defence to the claim and then initiated third party proceedings against SGIC,
alleging that, as statutory third party insurer
of the plant, the latter was
liable to indemnify it in respect of any liability to Wagner. SGIC denied
that any relevant liability
arose pursuant to its third party cover of the
plant.
16. The proceedings eventually came on for trial before Pirone DCJ pursuant
to the provisions of an order made by a Deputy Master of the District Court.
That order was expressed as follows:- "That there be
a trial at Adelaide on
the 20th day of April, 1993 at 10.15 am of the preliminary issue of fact
and/or fact and law namely whether
the incident referred to in the Particulars
of Claim occurring on 9 March, 1987 involved bodily injury to the plaintiff
caused by,
or arising out of the use of, the motor vehicle registered number
SA UWY-325 within the meaning of section 99(3) of the Motor Vehicle
Act, 1935
(as amended)."
17. For reasons expressed by him Pirone DCJ ultimately held that the question
as formulated should be answered
in the affirmative. He found SGIC, as third
party insurer of the plant, liable to indemnify the State.
18. This appeal challenges
the legal propriety of that conclusion. SGIC
asserts that, on the facts as above outlined, no circumstances ever arose
which, as
a matter of law, gave rise to any liability under the statutory
third party cover.
19. In examining that contention it is necessary
first to go to the relevant
statutory provisions.
20. The basic cover extended by SGIC to E and WS was that expressed in the
Fourth
Schedule ("the Schedule") to the Motor Vehicles Act, 1959, as amended
("the MVA") as under:-
5 "1. The insurer insures the owner
of the motor vehicle
and any other person who at any time drives the vehicle,
whether with or without the consent of the
owner, in respect
of all liability that may be incurred by the owner or other
person in respect of the death of, or bodily
injury to, any
person caused by, or arising out of the use of, the vehicle
in any part of the Commonwealth."
21. However,
the Schedule falls to be construed in light of the provisions of
subsection (3) of section 99 of the MVA, which expressly stipulate
that:-
"(3) For the purposes of this Part and the fourth schedule,
death or bodily injury will not be regarded as being caused
by or as arising out of the use of a motor vehicle if it is
not a consequence of -
(a) the driving of the vehicle;
