Kawada & Kawada

The case of Kawada & Kawada concerned the admissibility of intercepted communications in court proceedings. The central dispute revolved around whether evidence obtained in contravention of the *Telecommunications Act 1979* (Cth) could be admitted under the discretion provided by section 138 of the *Evidence Act 1995* (Cth), or if the mandatory exclusion provisions of section 63 of the *Telecommunications Act* prevailed. The court was required to determine the interplay between these two Commonwealth statutes.

The primary legal issue before the court was whether section 8 of the *Evidence Act* preserved the operation of section 63 of the *Telecommunications Act*, thereby rendering the discretion under section 138 of the *Evidence Act* inapplicable to evidence obtained in contravention of the *Telecommunications Act*. This involved interpreting the relationship between a general evidentiary statute and a specific statutory regime governing telecommunications interception.

The court reasoned that section 8(1) of the *Evidence Act* explicitly states that the *Evidence Act* does not affect the operation of other Acts. Applying this provision, the court found that section 63 of the *Telecommunications Act*, which mandates the exclusion of improperly obtained evidence, was not affected by the *Evidence Act* and therefore prevailed. This conclusion was supported by extrinsic materials, including explanatory memoranda and parliamentary debates, which indicated an intention to preserve the operation of specific Commonwealth laws, such as those relating to telecommunications interception. The court noted that section 63 and section 138 were directly inconsistent, with the former providing mandatory exclusion and the latter discretionary inclusion, and that section 8 dictated that the former would prevail.
