[This headnote is not to be read as part of the judgment]
In December 2022, the Court of Appeal made an order remitting to Duggan J in the Land and Environment Court the matter then before the Court (Broken Hill Cobalt Project Pty Ltd v Lord [2022] NSWCA 271) "on the question of quantification of the compensation payable by the appellants for the compensable losses identified at [43] and [44]-[46] of the primary judgment". Within those paragraphs, Duggan J had awarded a lump sum payment per annum of $20,000 to Mr Lord for each Exploration Licences (EL) held by the Cobalt Entities for impacts on management likely to be caused by the prospecting operations of the Cobalt entities, and for damage to the surface of the land inherent in the carrying out of prospecting operations by the Cobalt entities, on farm land owned by Mr Lord. However, the primary judge did not ascribe a specific sum from the lump sum to the respective heads of loss, nor did the primary judge provide reasons as to why the lump sum was awarded on an annual basis for each EL. Thus, the function of the remitter was for the "… further consideration and the provision of additional reasons" as to the nature of the lump sum.
On 7 July 2023, her Honour determined that the scope of the remitter permitted the making of further submissions as to the quantification of the compensation payable for the compensable losses identified in the specified paragraphs. Mr Lord subsequently sought to rely on an affidavit sworn by him on 29 August 2023 (Lord Affidavit), which spoke to the impact of Cobalt's activities on management decision making and inherent damage to the land caused by the prospecting operations. The primary judge ruled the Lord affidavit to be inadmissible.
Mr Lord sought leave to appeal from Duggan J's refusal to admit the Lord Affidavit pursuant to s 57(1) of the Land and Environment Court Act 1979 (NSW).
Three issues arose for determination. First, whether leave to appeal was required. Second, whether the appeal is on a question of law. Third, whether, if an error on a question of law is established, the error was material to the determination
The Court held (Ward P, Adamson JA and Preston CJ of LEC agreeing), granting leave to appeal but otherwise dismissing the appeal with costs:
