Section 51(v) of the Constitution of Australia
Section 51(v) of the Constitution of Australia is a subsection of Section 51 of the Constitution of Australia, a section central to the operation of Federalism in Australia, that gives the Commonwealth Parliament of Australia power to legislate on "postal, telegraphic, telephonic, and other like services".
In 1901, Section 51(v) was used by the Commonwealth to merge the colonial mail systems into the Postmaster-General's Department (or PMG). This body was responsible for telegraph and domestic telephone operations as well as postal mail. In 1975 the Australia Post was formed, taking over the postal functions of the PMG. Australia Post was corporatised in 1989, and its existence is therefore now supported under the corporations power.
The power also supports the issue of Australian postal stamps.
Other like services
The most problematic part of this power has been the words 'other like services'. The High Court has taken a flexible approach to interpreting this provision that has recognised that technology has changed since the constitution was written.
In the case of R v Brislan, in 1935, the High Court decided that s51(v) included the power to regulate radio broadcasting. However, in Brislan four of the judges held radio to be a wireless type of ‘telegraphic or telephonic service’, rather than an ‘other like service’.
In the 1965 case of Jones v Commonwealth (No 2) the High Court found that television broadcasting also fell under the ambit of s51(v). Although the communications power is often presumed to apply broadly as new technologies arise, it is uncertain, in the absence of litigation, whether Commonwealth regulation will be supported. For example, it is unclear whether regulation of internet content would be supported under Section 51(v).
The Commonwealth has already relied on Section 51(v) to regulate parts of the internet. For example, the Interactive Gambling Act (Cth), which regulates the operation of online casinos within Australia and advertising of online gambling, was based on s51(v). Other forms of gambling are a state and territory responsibility.
In March 2013 Australia's accession to the Council of Europe's Convention on Cybercrime came into force following the Cybercrime Legislation Amendment Act 2012 (Cth). The amendments to the Criminal Code which removed the earlier "carriage service" (telephone and internet) elements of some computer offences (in part 10.7) were apparently supported by the s51(xxix) external affairs power (arising from obligations under an international treaty). This may mean that ratification of the Convention extended the Commonwealth power in this area beyond the s51(v) power, avoiding the need to rely on the definition of 'other like services'.
