Factual Background
2 In June 2000, the Plaintiff, Robbert Weibren Kuppers, was employed by the Defendant, the New South Wales Fire Brigades, as Station Officer at Armidale Fire Station. He had been a fireman since 1973 and a station officer since December 1985. On Wednesday, 14 June 2000, the Plaintiff was involved in an incident where a pumper (a fire-fighting vehicle) rolled forward out of the fire station and was struck by a cattle truck after the Plaintiff had succeeded in stopping the pumper. The Plaintiff was inside the pumper on the passenger side putting items into the glove box as it commenced to roll out of the station. By the time he succeeded in stopping it, the pumper was on the street and was struck by the cattle truck.
3 On 16 June 2000, the Plaintiff consulted his general practitioner, Dr Watts, with respect to complaints arising from the accident on 14 June 2000. Counselling was organised for the same day and physiotherapy for the following week. On 16 June 2000, the Plaintiff consulted Dr Allen, Psychologist, for counselling.
4 On Saturday, 17 June 2000, the Plaintiff was riding a motor cycle when he lost control of the motor cycle, crossed the highway and struck an embankment or tree, thereby sustaining serious injury. The Plaintiff was not riding the motor cycle for a purpose related to his employment.
5 On 14 November 2000, the Plaintiff filed an Application for Determination by the Compensation Court of New South Wales claiming weekly compensation and hospital and medical expenses under the Workers Compensation Act 1987 ("the Act") for injuries alleged to have resulted from the incident at work on 14 June 2000. Following a hearing extending over several days, Campbell CJ, on 26 March 2003, made findings in favour of the Plaintiff and made an award of weekly compensation under s 36 of the Act and an order for payment of hospital and medical expenses under s 60 of that Act.
6 In the present proceedings before this Court, the Plaintiff sues the Defendant for damages alleging negligence on the part of the Defendant on 14 June 2000 and alleging that such negligence caused the motor cycle accident on 17 June 2000 in which the Plaintiff sustained serious injuries. There are two sets of proceedings, No. 20942 of 2001 and No. 20293 of 2003, both of which arise from the same events. I was informed at the hearing that the second set of proceedings may be explained by reference to the Motor Accidents Compensation Act 1999. In any event, nothing turns at present on the existence of two sets of proceedings before this Court. The parties agree that the same separate question arises for determination in each case.
7 In its Defence, the Defendant denied that the motor cycle accident on 17 June 2000 occurred as a consequence of injuries and ongoing disabilities arising from the accident on 14 June 2000. The issue estoppel question arises from the Amended Reply filed for the Plaintiff which states:
"5. The Plaintiff asserts that as a result of the said judgment [of Campbell CJ] the Defendant is estopped from denying and is prevented from adducing evidence to contradict the following matters:
(i) The Plaintiff sustained psychological injury in the course of his employment with the Defendant on 14 June 2000.
