Leghaei v Director-General of Security & Anor

In *Leghaei v Director-General of Security & Anor*, the High Court of Australia considered an appeal from a decision of the Federal Court of Australia concerning the Director-General of Security's (DG) power to issue a 'control order' under the *Security Legislation Amendment (Terrorism) Act 2002* (Cth). The appellant, Mr Leghaei, had been the subject of a control order which imposed significant restrictions on his liberty and activities. The dispute centred on the lawfulness of this order and the interpretation of the relevant provisions of the *Suppression and Prohibition of Terrorism Financing Act 2004* (Cth) and the *Crimes (Traffic and Transport) Act 1990* (NSW), which were incorporated by reference into the control order.

The High Court was required to determine whether the DG had acted within his statutory powers when issuing the control order, particularly in relation to the alleged financing of terrorism. Key legal issues included the proper construction of the definition of 'terrorist act' and 'terrorist organisation' under the relevant Commonwealth legislation, and whether the evidence before the DG was sufficient to satisfy the statutory preconditions for issuing a control order. The Court also had to consider the extent to which the DG could rely on information obtained from foreign intelligence agencies and the admissibility and weight of such information in the control order process.

In its reasoning, the High Court affirmed the broad scope of the DG's powers under the *Suppression and Prohibition of Terrorism Financing Act 2004* and the *Crimes (Traffic and Transport) Act 1990*. The Court held that the DG was entitled to form a belief on reasonable grounds that the appellant had engaged in conduct that constituted or facilitated the financing of terrorism, based on the material before him. The principles applied by the Court emphasised the importance of national security and the legislative intent to provide the DG with robust powers to prevent terrorist financing. The Court found that the control order was validly made and that the restrictions imposed were a proportionate response to the identified risks.
