Lansen v Minister for Environment and Heritage (No 3)

Lansen v Minister for Environment and Heritage (No 3) involved the applicants, the Lansens, challenging the Minister for Environment and Heritage’s decision to approve a development proposal. The dispute was heard by the Federal Court of Australia, which was required to determine the appropriate costs order under section 43 of the Federal Court of Australia Act 1976 (Cth). The central legal issues were whether the public interest considerations in the litigation warranted a departure from the usual costs order and, if so, to what extent. The court also had to consider whether the applicants’ standing to sue was valid.

The court found that the proceeding primarily involved issues of critical importance concerning the proper construction of the Environment Protection and Biodiversity Conservation Act 1999 (Cth). These issues were of general importance to the Minister and the public, as they concerned the administration of the Act and the protection of the Australian environment. The court held that there were sufficient public interest considerations to justify a departure from the ordinary rule that a wholly successful respondent is awarded costs. However, the court was not persuaded that these considerations outweighed the usual costs order. The court decided that the applicants should pay 25 per cent of the Minister's and the Minister for Resources, Management and Planning's (MRM) taxed costs, reflecting the public interest aspects and the outcome of the case.

In conclusion, the Federal Court ordered that the applicants pay 25 per cent of the Minister’s and MRM’s costs of the proceeding, excluding the costs related to the applicants’ notice of motion of 29 April 2008. This decision balanced the public interest considerations with the outcome of the litigation, ensuring a fair costs order while recognising the importance of the issues at hand.
