Grass v Slattery

The case of Grass v Slattery involved a dispute where Mrs Grass, a Philippine national, challenged the actions of Ms Slattery and other respondents, who were administrative officials of the Department of Immigration and Border Protection. The applicants sought to establish the tort of misfeasance in public office, arguing that the respondents had acted without lawful authority and with improper motives, causing them loss and damage. The respondents denied these allegations, asserting that their actions were within the scope of their public duties and were not pursued with malice or recklessness. The court had to determine whether the respondents' actions constituted the exercise of public power, whether they acted with malice, and whether they had knowledge or were reckless about the possibility of causing injury. Additionally, the court needed to decide if the Commonwealth of Australia could be held vicariously liable for the respondents' actions and if the applicants had indeed suffered damage.

The court examined the elements required to establish the tort of misfeasance in public office. It considered whether the respondents' actions were an exercise of public power, whether they were pursued with malice, and whether there was knowledge or reckless indifference to the possibility of causing injury. The court also assessed whether the Commonwealth could be held vicariously liable for the actions of the respondents and if the applicants had indeed suffered damage. After reviewing the documentary evidence and the affidavits provided by Ms Slattery and Ms Penhaligon, the court found that the applicants could not establish the tort of misfeasance in public office. The court concluded that the respondents' actions were not pursued with malice and that there was no evidence of knowledge or reckless indifference to the possibility of causing injury. Consequently, the court dismissed the application with costs.

The final orders of the court were that the amended originating application and the amended statement of claim be dismissed, and that the applicants pay the respondents' costs of and incidental to this proceeding as assessed or agreed. The dismissal of the application meant that the applicants' claims for misfeasance in public office and vicarious liability were not substantiated, and the court held that the Commonwealth was not vicariously liable for the respondents' actions.
