What happened
The appellants, comprising 34 Australian and United States companies that owned or exclusively licensed copyright in thousands of commercially released films and television programs (with 86 films forming a sample in evidence), commenced proceedings against iiNet Limited, the third-largest Australian internet service provider at the relevant time with approximately 490,000 customers. The core allegation was that iiNet had infringed the appellants' copyright by authorising its customers' primary infringements. Those primary infringements occurred when customers used the BitTorrent peer-to-peer file sharing system to download the appellants' films and, in doing so, automatically made them available online to other users in breach of the exclusive right to communicate the film to the public under s 86(c) of the Copyright Act 1968 (Cth).
From August 2007, the Australian Federation Against Copyright Theft (AFACT), acting on behalf of the appellants, engaged DtecNet Software APS to monitor infringing activity. From June 2008, DtecNet focused on iiNet customers using a modified BitTorrent client (the DtecNet Agent) that both participated in swarms and logged IP addresses of other peers sharing .torrent files associated with the appellants' films. Between July 2008 and August 2009, AFACT sent iiNet approximately weekly "Notices of Infringement of Copyright". Each notice included a spreadsheet listing IP addresses, dates, times, and hash values said to evidence multiple infringements by iiNet customers. The notices asserted that iiNet's failure to prevent continuing infringements might itself constitute authorisation and requested that iiNet prevent the identified customers from infringing.
iiNet's Customer Relationship Agreement (CRA) expressly prohibited use of its service to commit offences, infringe rights, or for illegal purposes (cll 4.1 and 4.2). It also permitted iiNet to suspend or terminate service for breach, including where iiNet reasonably suspected illegal conduct (cl 14.2). Despite this, iiNet took no steps to warn, suspend or terminate any accounts in response to the AFACT notices. iiNet's responses to AFACT emphasised that the data did not sufficiently identify individual customers (dynamic IP addresses could correspond to multiple users or shared connections such as libraries or wi-fi hotspots), that the methodology was opaque, and that allegations of infringement were properly a matter for law enforcement rather than the ISP. iiNet did, however, suspend or terminate accounts in other contexts, such as non-payment or spamming, where it could verify issues independently.
By mid-2008, more than half of iiNet's traffic volume involved BitTorrent file sharing, and it was common knowledge within the industry that the protocol was frequently used for infringing purposes, although it was also capable of non-infringing uses. iiNet maintained a website notice warning that hosting or posting illegal copyright material breached the CRA and could result in suspension or termination. It also published contact details for copyright notices under the safe harbour provisions (ss 116AA-116AJ) and offered a "Freezone" service providing access to licensed, non-infringing content including films and television programs.
Proceedings were instituted in the Federal Court on 20 November 2008. During discovery, iiNet was provided with further DtecNet data enabling identification of 20 specific customer accounts (the "R20 accounts") that had repeatedly appeared in the AFACT notices. By the time of trial, iiNet did not dispute the underlying primary infringements alleged in the notices between 23 June 2008 and 9 August 2009. Cowdroy J at first instance held that iiNet had not authorised the infringements, placing emphasis on the fact that the BitTorrent system itself, rather than iiNet's provision of internet access, was the means of infringement. The Full Court of the Federal Court (Emmett and Nicholas JJ, Jagot J dissenting) dismissed an appeal, although all members found that the primary judge had not correctly applied the statutory test in s 101(1A). The High Court granted special leave and heard the appeal in 2011, delivering judgment on 20 April 2012. The Court unanimously dismissed the appeal with costs, holding that iiNet had not authorised its customers' infringing acts.
Why the court decided this way
The High Court's reasoning centred on the proper construction and application of ss 101(1) and 101(1A) of the Copyright Act within the broader statutory framework that had been amended by the Copyright Amendment (Digital Agenda) Act 2000 (Cth) to address new communications technologies. French CJ, Crennan and Kiefel JJ (with whom Gummow and Hayne JJ agreed in separate reasons) emphasised at [5] and [71] that whether a person has authorised an infringing act "depends upon all the facts of the case" and is an inference to be drawn from those facts. The three mandatory considerations in s 101(1A) were therefore not to be applied rigidly or in isolation but as part of a holistic assessment.
On the first factor (extent of power to prevent the act under s 101(1A)(a)), the Court found iiNet possessed no direct technical power. It had no involvement with any component of the BitTorrent system, could not modify the BitTorrent client, could not monitor the content of communications once data packets left its network, could not take down infringing material stored on customers' computers, and could not block specific .torrent files or swarms ([47]-[50]). The only power available was indirect and contractual: termination of a customer's entire internet service under the CRA. That power was limited because termination would also prevent all non-infringing uses, customers could readily switch to another ISP, and multiple users might share a single IP address. The Court distinguished the facts from University of New South Wales v Moorhouse (1975) 133 CLR 1, where the university provided both the copyrighted books and the photocopier on its premises and exercised direct control over the library environment ([50], [55]). iiNet exercised no equivalent dominion over the BitTorrent system or the content communicated.
The second factor (nature of the relationship under s 101(1A)(b)) reinforced the absence of authorisation. The CRA expressly required compliance with all laws and prohibited infringing or illegal use (cll 4.1, 4.2). Far from purporting to grant any right to infringe, iiNet's contractual terms positively disapproved of such conduct. Customers could not reasonably infer from iiNet's inaction or media releases that iiNet was willing to countenance infringement or that it possessed authority to authorise making the films available online ([63]-[65]). The relationship was that of a carriage service provider supplying a general-purpose facility, not a party granting permission for specific infringing acts. Section 22(6) made clear that iiNet was not the person responsible for determining the content of communications, and s 112E provided that merely providing facilities for communications does not constitute authorisation ([20]-[21]).
On the third factor (reasonable steps under s 101(1A)(c)), the Court held that the AFACT notices did not provide a reasonable basis for iiNet to send warnings or threaten suspension or termination. The notices identified IP addresses but did not disclose the full DtecNet methodology until expert evidence was filed in the proceedings. Even after identification of the R20 accounts, acting solely on the notices would have required iiNet to undertake its own costly verification, exposing it to the risk of wrongful termination claims if the data proved inaccurate. Warnings would need to be followed by further monitoring to check compliance, and termination would not guarantee cessation of infringement because a customer could simply obtain service from a competitor ([67]-[77]). The absence of an industry code of practice binding all ISPs (as contemplated by s 101(1A)(c) and the safe harbour provisions) further undermined the reasonableness of expecting unilateral action by iiNet. The Court noted that iiNet's media releases asserting that proof in court should be required before disconnection did not amount to "tacit approval" sufficient to constitute authorisation when viewed against the statutory factors ([68], [158] in the Full Court reasons, distinguished).
Both sets of reasons concluded that the appellants' argument effectively sought to impose obligations on ISPs that the Copyright Act does not enact. The statutory tort of authorisation, while economically rational for cost-effective enforcement, could not be stretched to require ISPs to act as proxy copyright enforcers on the basis of the material supplied. The appeal was therefore dismissed.
Before and after state of the law
Prior to the 2000 amendments, the concept of authorisation derived from common law authorities interpreting s 1(2) of the Copyright Act 1911 (Imp), which had been adopted in Australia. Cases such as Adelaide Corporation v Australasian Performing Right Association Ltd (1928) 40 CLR 481 established that authorisation required some power or authority to control the infringing act and that mere indifference or inactivity did not necessarily constitute permission ([42]-[49]). Moorhouse clarified that a person with control over the means of infringement who makes those means available, knowing or having reason to suspect likely infringing use and failing to take reasonable steps to limit that use, may authorise resulting infringements ([50]-[56]). Gibbs J's formulation in Moorhouse at 13 directly influenced the text of s 101(1A)(a) and (c). Tape Manufacturers (1993) 176 CLR 480 confirmed that sale of articles with lawful uses does not authorise infringement where the vendor lacks control over the purchaser's ultimate use.
The Copyright Amendment (Digital Agenda) Act 2000 (Cth) introduced the new right to communicate to the public (ss 10(1), 86(c)), inserted s 101(1A) to partially codify the common law principles from Moorhouse and related authorities, enacted s 112E to implement the WIPO Copyright Treaty agreed statement that mere provision of physical facilities does not amount to communication, and added s 22(6) to exclude ISPs from primary liability for content they do not determine ([22]-[30]). The subsequent US Free Trade Agreement Implementation Act 2004 (Cth) added the safe harbour provisions (ss 116AA-116AJ), which limit remedies against compliant carriage service providers but were held inapplicable on the facts.
After the decision, the law remains that authorisation is a fact-specific inquiry governed by s 101(1A). The judgment confirms that ISPs are not required to act as copyright police on the basis of notices that do not supply verifiable, court-ready evidence. It underscores that legislative solutions, such as graduated response schemes or industry codes with cost-sharing (expressly noted at [78] and [84]), are preferable to judicial expansion of secondary liability. The safe harbour provisions and s 112E continue to protect ISPs who do not determine content, while the distinction between primary and secondary infringement is preserved. No obligation is imposed on ISPs to monitor or terminate on the basis of allegations alone where doing so would be unreasonable having regard to cost, risk and efficacy.
Key passages with plain-English translation
Paragraph [5]: "The key question in the appeal, whether iiNet authorised its customers' infringing acts, 'depends upon all the facts of the case'."
Plain English: The judges are reminding everyone that there is no simple checklist; you must look at the whole picture, not just whether iiNet knew about the downloads.
Paragraph [47]: "iiNet had no involvement with any part of the BitTorrent system and therefore has no power to control or alter any aspect of the BitTorrent system, including the BitTorrent client."
Plain English: iiNet cannot reach inside customers' computers or change how BitTorrent works; its only lever is to cut off the entire internet connection, which is a blunt and indirect tool.
Paragraph [63]: "'Countenance' is a long-established English word which, unsurprisingly, has numerous forms and a number of meanings which encompass expressing support, including moral support or encouragement. In both the United Kingdom and Canada, it has been observed that some of the meanings of 'countenance' are not co-extensive with 'authorise'. Such meanings are remote from the reality of authorisation which the statute contemplates."
Plain English: Just because the old cases used words like "countenance", you cannot pick the widest dictionary meaning and say that doing nothing equals approval. The statute now tells us what matters: power, relationship and reasonable steps.
Paragraph [71]: "It is a question of fact in each case what is the true inference to be drawn from the conduct of the person who is said to have authorized."
Plain English: Whether someone has authorised infringement is decided by looking at what they actually did (or did not do) and asking what that conduct really implies in the real world.
Paragraph [78]: "This final conclusion shows that the concept and the principles of the statutory tort of authorisation of copyright infringement are not readily suited to enforcing the rights of copyright owners in respect of widespread infringements occasioned by peer-to-peer file sharing, as occurs with the BitTorrent system. The difficulties of enforcement which such infringements pose for copyright owners have been addressed elsewhere, in constitutional settings different from our own, by specially targeted legislative schemes..."
Plain English: The authorisation rules were not designed for mass internet file sharing. Parliament should fix this with new laws that set up proper systems for ISPs and copyright owners to share the burden, rather than expecting judges to stretch the old rules.
What fact patterns trigger this precedent
This precedent is triggered where an ISP provides general internet access that customers use to engage in peer-to-peer file sharing via protocols such as BitTorrent, the ISP receives notices from copyright owners identifying IP addresses and alleged infringements, the ISP has contractual power to terminate service for breach but no technical ability to remove specific infringing files or block particular swarms, and the ISP declines to act on the notices because they lack sufficient verifiable detail or because acting would be unreasonable having regard to cost, risk of error, potential customer claims, and the limited efficacy of termination (customers can switch providers). The precedent applies whenever the s 101(1A) factors, weighed together, show that the ISP's power is only indirect, the contractual relationship does not purport to authorise infringement, and no industry code or court order compels specific remedial steps. It is not engaged where the ISP hosts infringing content, indexes torrent files, modifies the file-sharing software, or expressly encourages infringement, as those facts would strengthen the inference of authorisation (distinguished from cases such as Cooper and Kazaa referenced at [72]).
The ratio is engaged whenever a court must decide whether mere provision of internet carriage, coupled with knowledge from third-party notices that do not approximate admissible evidence, crosses the line into authorisation. It is not limited to cinematograph films; the same analysis applies to any copyright subject-matter where the alleged secondary infringer is a carriage service provider within the meaning of the Telecommunications Act 1997 (Cth) and relies on ss 22(6), 112E and the safe harbour provisions.
How later courts have treated it
The judgment itself grounds its treatment of prior authorities. It distinguished Moorhouse on the basis that the university controlled both the copying device and the premises and supplied the copyrighted works, whereas an ISP supplies only a general communications facility over which it has no content control ([50], [55]). Adelaide Corporation was cited for the proposition that permission requires some power to control the specific act and that indifference does not necessarily establish authorisation ([42], [48]). CBS Songs was cited for the principle that selling equipment with copying capacity does not authorise infringement where the seller does not purport to grant the right to copy ([38]). Jain was distinguished because the director there had effective control over the venue where unlicensed performances occurred and did nothing to stop them, whereas iiNet lacked equivalent control over its customers' computers ([71]).
The judgment notes that the statutory tort of authorisation is not well suited to peer-to-peer infringements and that legislative schemes (such as those later enacted in the United Kingdom and New Zealand) are the appropriate response ([78], [84]). It affirms that s 112E, while seemingly redundant, confirms that provision of facilities alone does not constitute authorisation ([20], [131] in the Full Court). Subsequent references in the reasons to the need for an industry code binding all ISPs and the risks of unilateral termination reflect the continuing relevance of the safe harbour conditions in ss 116AA-116AJ, which require reasonable steps but were held inapplicable on these facts. The decision therefore narrows the circumstances in which an ISP will be held to have authorised infringement by emphasising the limited nature of its power and the unreasonableness of expecting it to act as a substitute for court processes or comprehensive legislative schemes.
Still-open questions
The judgment leaves open what would constitute "reasonable steps" where an ISP receives more detailed, court-verifiable evidence of infringement or where an industry code of practice under the Copyright Regulations has been developed and adhered to by all major ISPs ([67], [76]). It does not decide whether a graduated response system (warning, then suspension, then termination) would be reasonable if the underlying notices supplied admissible evidence and included a mechanism for cost-sharing between copyright owners and ISPs. The precise threshold at which knowledge from notices becomes sufficient to trigger a duty to investigate or act remains fact-dependent, as does the question whether an ISP that voluntarily implements a system for verifying notices could still avoid liability if that system proves imperfect.
The interaction between the authorisation provisions and the safe harbour limitations on remedies (particularly s 116AG(3)(b), which contemplates court orders for termination of specified accounts) is noted but not resolved, because iiNet did not rely on the safe harbours in the High Court. Whether termination of an account can ever be a reasonable step when it affects non-infringing uses and when customers can migrate to competitors is left for future cases with different evidence of efficacy. The judgment expressly records that the concept of authorisation may not be the best tool for widespread peer-to-peer infringement and that specially targeted legislative schemes with judicial oversight or industry protocols are preferable; the parameters of any such future scheme remain open. Finally, the Court did not need to decide the notice of contention concerning obligations under the Telecommunications Act 1997 (Cth) that might prohibit disclosure or termination based on unverified allegations, leaving that statutory interaction unresolved.
