Legislation

Elements of the offence

To prove this charge the Prosecution must prove:

  1. The accused is in possession or control of data; and
  2. The accused intends on using the data to commit or facilitate the commission of a serious computer offence.

Element 1: The accused is in possession or control of data
An accused will be in possession or control of data when a person:1

  1. has possession of a computer or data storage device that holds or contains the data; or
  2. has possession of a document in which the data is recorded; or
  3. has control of data held in a computer that is in the possession of another person (whether the computer is in Victoria or outside Victoria).

‘Data’ means information in any form and any program or part of a program.2

‘Data held in a computer’ includes data entered or copied into the computer, data held in any removable data storage device for the time being in the computer and data held in a data storage device on a computer network of which the computer forms part.3

A ‘data storage device’ means anything (for example, a disk or file server) containing or designed to contain data for use by a computer.4

Element 2: The accused intends on using the data to commit or facilitate the commission of a serious computer offence
A serious computer offence means an offence against ss 247B, 247C or 247D of the Act.5

An offence against s 247B means knowingly causing an unauthorised computer function with the intention of committing or facilitating the commission of a serious offence.6 A ‘serious offence’ is an offence punishable by 5 years imprisonment or more on conviction for a first offence.7

An offence against s 247C means knowingly causing the unauthorised modification of data held in a computer intending the modification to impair access to, reliability, security or operation of any data held in a computer, or being reckless as to any such impairment.8

An offence against s 247D means knowingly causing any unauthorised impairment of electronic communication to or from a computer intending to impair electronic communication to or from the computer or being reckless as to any such impairment.9

The prosecution must prove that the accused intends to use the data to commit or facilitate the commission of a serious computer offence. It is not enough that the person is merely in possession of the data.

Can they prove you intended on committing a serious computer offence? 

It is not necessary for the prosecution to prove that the accused would actually be able to commit or facilitate the commission of a serious computer offence with the data in their possession or control. A person may be found guilty of this offence even if committing the serious computer offence is impossible.10

Defences

Defences to this charge ordinarily turn on some element of the offence not being made out. These defences include:

  • The accused did not possess the data; and
  • It is impossible to prove that the accused intended to use the data to commit a serious computer offence.

Other defences to this charge include duress and mental impairment.

You should ring us and discuss your case if you have been charged. Deciding on whether to plead guilty or not has serious implications for you and should be made after proper discussions with a criminal lawyer.
