66 BJD is a disease of adult cattle caused by a bacterium known as Mycobacterium paratuberculosis. The disease is characterised by chronic diarrhoea, progressive emaciation and death within a few months. Affected cattle shed the bacteria in their faeces. Other animals are infected when they ingest contaminated feed or water. Calves less than six months of age are most susceptible to the infection. Older cattle appear to be relatively resistant to infection and only a small proportion of cattle exposed as adults subsequently carry the disease or succumb to it. Although BJD is incurable and generally fatal to cattle, consumption of meat from cattle infected with the disease is not harmful to humans.
67 In 1992 BJD was a disease in respect of which compensation was payable under the Cattle Compensation Act (now repealed). By s.12(1) of that Act, a fund was established, called the Cattle Compensation Fund, which was to be applied in the payment of claims for compensation made in accordance with the provisions of the Act and in the payment of expenses incurred in obtaining determinations of the value of cattle for the purpose of paying compensation to the owners.
68 By s.5(1)(a), so far as is presently relevant, compensation was payable to the owner of any cattle destroyed pursuant to an order made under the authority of any Act because such cattle were suffering from or were suspected to be suffering from a disease, defined by the Act as including BJD. By s.6, the amount of compensation payable was the market value of the cattle.
69 Section 7 provided, so far as is relevant:
"(1) For the purposes of this Act, the market value of any cattle … is to be determined by agreement between the owner of the cattle … and:
(a) in the case of cattle to which section 5(1)(a) … applies - the person or approved person, as the case may be, who made or gave the order for destruction of the cattle;
…"
70 Section 8 relevantly provided:
"(1) Compensation is payable under this Act only if the owner of the cattle … makes an application for compensation in an approved form within 60 days after the death or destruction of the cattle … . Any such application must be verified by statutory declaration as set out in the approved form.
…
(3) The owner is to forward with the application a certificate in the approved form completed by:
(a) the person with whom the owner is required to reach an agreement in respect of the market value of the cattle or carcass under section 7(1); or
(b) a person appointed by the Minister for the purposes of this subsection.
(4) No compensation shall be payable:
…
(d) unless the Chief, Division of Animal Industries is satisfied:
…
(ii) that the owner claiming compensation has complied with this Act with respect to applications and claims for compensation."
71 The funding of compensation payable from the Cattle Compensation Fund under the Cattle Compensation Act was provided pursuant to the Cattle Compensation (Taxation) Act 1951 (NSW), as amended. The principal sources of revenue for the fund were a stamp duty payable on every head of cattle slaughtered at abattoirs and slaughterhouses in New South Wales, interest in accumulated reserve funds on fixed deposit with Treasury, and certain rebates from the Commonwealth Government. The diseases occasioning slaughter of cattle for which compensation was payable from the fund were expanded over time and by 1983 included BJD.
72 A circular issued by NSWAg to its senior officers in June 1984 (No 84/24) explained in detail the operation of the Cattle Compensation Fund and the procedures for obtaining compensation for owners of slaughtered cattle. A further circular dated in July 1989 (No 89/36) dealt specifically with NSWAg's policy and procedures for the eradication of BJD. There was no reference in this circular to depopulating (i.e. slaughtering) a whole herd to ensure eradication of the disease.
73 On 21 December 1990, NSWAg published circular 90/50 which amplified the procedures for compensation stated in circular 84/24. The circular referred in particular to the depopulation of whole herds and set out twelve steps which had to be followed in the process of depopulation and obtaining payment of a claim from the Cattle Compensation Fund. Step 1 required confirmation of BJD in the herd, preparation of a report by NSWAg's field staff containing specified information, and the obtaining of approval for the depopulation from the Chief, Division of Animal Health. Step 2 required that the value of the cattle to be slaughtered be ascertained and agreed between the owner and NSWAg's officer.
74 On 3 January 1992, NSWAg issued circular 92/1, replacing circular 89/36 and setting out in more detail NSWAg's policies and procedures for the eradication of BJD in New South Wales. The action to be taken by district veterinarians or district officers responsible for administering the policy in the field included carrying out investigation of herds and, if tests for BJD proved positive, discussing with the owner options for controlling and eradicating the disease in that herd. The first option was stated to be "total depopulation of the herd" .
75 On 8 May 1992, Dr Salmon wrote to the Plaintiff regarding suspected BJD on Malton and referring to the possibility of mandatory quarantining of BJD infected herds in early 1994. On 15 and 22 June, Dr Salmon had preliminary discussions with the Plaintiff concerning testing for BJD.
76 On 29 June 1992, the Premier of New South Wales wrote to the Minister for Agriculture advising that he had given approval in principle for the use of $2M from the Cattle Compensation Fund for research relating to the cattle industry. As at 1 July, the Cattle Compensation Fund stood at $9,014,000, which included $8,250,000 on fixed deposit with Treasury.
77 On 9 July 1992, a legal officer within NSWAg advised that funds in the Cattle Compensation Fund could not be applied for research without an amendment to the Cattle Compensation Act .
78 On 17 July 1992, the Minister for Agriculture wrote to the head of his department requiring preparation of a letter to the Premier opposing use of the funds in the Cattle Compensation Fund for research purposes. Shortly thereafter, a draft letter was prepared in response to the Minister's request, urging retention of the money in the Cattle Compensation Fund for the purposes of compensating owners of slaughtered cattle, saying that the Fund was essential to enable eradication of BJD as well as another major cattle disease.
79 A financial analysis of the Cattle Compensation Fund was prepared in support of the arguments set out in the draft letter. The analysis showed the sources of revenue of the Fund and its projected expenditure on compensation claims. The projection showed that claims on the Fund were expected to increase very substantially from the 1992/93 year onwards. The figures showed that, assuming that the sum of $2M was not withdrawn from the Fund for research purposes, the Fund would be reduced to $1,525,000 by the close of the 1999/2000 year. However, if the $2M had been withdrawn immediately, there would still have remained in the Fund an amount in excess of $6.5M to meet expected claims during the 1992/93 year - i.e., the year in which the Plaintiff's claim was expected to occur.
80 A handwritten note dated 4 August 1992, author unknown but produced by NSWAg under a Notice to Produce, contains the statement "CC Fund down to $1.5M by 2000 - CRC [i.e. Cattle Research Centre] Armidale - Premier agrees to $2M - if so Fund will be broke by 2000" .
81 On 7 August 1992, NSWAg issued a circular to its senior officers advising that the maximum compensation from the Cattle Compensation Fund had been increased to $2,000 per head of cattle. There was no indication in this circular that NSWAg's policy relating to administration of the Fund might be under review.
82 On 11 August 1992, a legal officer within NSWAg prepared a draft Cabinet Minute approving amendment of the Cattle Compensation Act to permit "the use of surplus funds [in the Cattle Compensation Fund] for research and development projects in the cattle industry" .
83 On 28 August 1992, Dr Salmon had the conversations with Mr Roe, his superior, and with Mr Peter Falls which I have recounted in paragraphs 32 to 34. It was in reliance upon this conversation with Dr Salmon that the Plaintiff began to move its agisted stud cattle onto Malton in early September 1992. It must be borne in mind, however, that the Plaintiff did not tell Dr Salmon on 28 August or at any time before 29 September that, in reliance upon what he had said on 28 August, it would immediately begin moving its agisted stud cattle to Malton for valuation.
84 On 9 September 1992, a valuer began valuing the Plaintiff's stud cattle at Malton , including stud cattle which were being brought to Malton from agistment. Clearly, the Plaintiff had made a decision shortly after 28 August to bring the agisted cattle to Malton for valuation and had begun to implement its decision. The stud cattle valuations were completed on Malton on 15 September. Mr Peter Falls said in paragraph 11 of his affidavit of 7 July 1997:
"The valuation took place over four (4) days being the 9th, 10th, 14th and 15th September, 1992. It took my father and I ten days working fifteen hours per day to ensure all beasts had correct ear-tags to match tattoos and pedigrees and sort all the stock on or transported to 'Malton'."
