Overview: This proposal sets out a doctrinal LLM research project examining how the Online Safety Act 2023 reshapes intermediary liability for user-to-user platforms in the United Kingdom. It evaluates the Act’s systemic duties of care and Ofcom’s enforcement architecture against the pre-existing conduit, caching and hosting safe harbours, and asks whether the new regime strikes a defensible balance between online safety and freedom of expression under Article 10 of the European Convention on Human Rights.
The regulation of online intermediaries has moved, within a single legislative generation, from a model of conditional immunity to one of affirmative, systemic responsibility. For more than two decades the liability of platforms hosting user-generated content in the United Kingdom was governed principally by the “hosting” safe harbour transposed from Article 14 of the e-Commerce Directive (2000/31/EC) via the Electronic Commerce (EC Directive) Regulations 2002, supplemented by sector-specific defences such as section 5 of the Defamation Act 2013. Under that framework an intermediary generally escaped liability for third-party content provided it had no actual knowledge of unlawful material and acted expeditiously to remove it once notified. The prohibition on general monitoring obligations, affirmed by the Court of Justice of the European Union in cases such as L’Oréal v eBay and Google France, reinforced a largely reactive, notice-driven settlement.
The Online Safety Act 2023 (OSA), which received Royal Assent on 26 October 2023, marks a decisive departure from this paradigm. Rather than conditioning immunity on responses to individual items of content, the Act imposes forward-looking “duties of care” on providers of regulated user-to-user and search services, requiring them to assess risk, design systems and processes to mitigate illegal content and content harmful to children, and evidence compliance to a strengthened regulator, Ofcom. The shift is conceptual as much as procedural: liability is reframed around the governance of a service as a whole rather than the status of any single post. This proposal situates that transition within the wider scholarly debate on intermediary liability and interrogates its implications for the rule of law and for freedom of expression.
The central problem the research addresses is one of balance and legal certainty. The OSA’s systemic duties are novel, and their precise content is elaborated not only in the statute but through codes of practice and guidance issued by Ofcom. This layered, co-regulatory structure raises a genuine question whether the obligations placed on platforms are sufficiently foreseeable to satisfy the “prescribed by law” requirement that conditions any lawful interference with expression under Article 10(2) ECHR. A related concern is the risk of “collateral censorship”: where the cost of non-compliance is severe, risk-averse providers may over-remove lawful but contentious speech, chilling legitimate debate.
The topic is both current and under-examined. Ofcom’s phased implementation, including the finalisation of illegal-harms codes, means the regime is only now becoming operative, and sustained doctrinal analysis of how its duties interact with the surviving safe-harbour provisions remains sparse. A rigorous, black-letter evaluation is therefore timely and offers practical value to platform operators, policymakers and civil-society observers seeking to understand where liability now lies.
The aim of the dissertation is to critically evaluate whether the intermediary liability regime introduced by the Online Safety Act 2023 achieves a proportionate balance between protecting users from online harm and preserving freedom of expression, and to assess the coherence and enforceability of Ofcom’s supervisory role. The research pursues five objectives:
The objectives are operationalised through three research questions:
The scholarly literature on intermediary liability provides the conceptual scaffolding for the study. Riordan’s systematic treatment of intermediary liability offers the doctrinal taxonomy — primary, accessory and secondary liability — against which the OSA’s systemic model can be positioned, while the comparative essays collected by Frosio situate the United Kingdom within a global shift away from broad immunities. These works establish that “intermediary liability” is not a single rule but a spectrum of allocations of responsibility, and that recent reform efforts across jurisdictions share a turn towards proactive, systems-based duties.
A second strand concerns the human-rights dimension. Laidlaw’s gatekeeper theory frames dominant platforms as privatised regulators of public discourse and argues that their governance engages Convention values even where the state is not the direct actor. This literature is essential to RQ2 and RQ3 because it supplies the analytical vocabulary — proportionality, procedural fairness and the chilling effect — through which the Act’s duties must be tested. The Strasbourg jurisprudence, notably Delfi AS v Estonia, illustrates both the Court’s willingness to countenance proactive obligations for certain high-risk actors and the contested boundaries of that acceptance.
A third strand is the policy and design literature that shaped the Act itself. The statutory duty-of-care concept advanced by Woods and Perrin, and later developed through the Online Harms White Paper, provides the regulatory theory underpinning the OSA and allows the research to trace how an academic proposal became binding law. Finally, the comparative material on the EU Digital Services Act supports the fifth objective by offering a contemporaneous regime with analogous aims but distinct techniques, including retained conditional liability alongside due-diligence obligations. A preliminary reading suggests a research gap: existing commentary tends either to describe the OSA’s provisions or to critique its policy aims, but few studies rigorously analyse the doctrinal interaction between the new duties and the surviving safe harbours, or test that interaction against the legality limb of Article 10. This dissertation is designed to occupy that gap.
The study adopts a doctrinal (black-letter) methodology as its primary method, supplemented by a focused comparative analysis. Doctrinal research is appropriate because the research questions are fundamentally concerned with the content, coherence and interpretation of legal rules: what the duties require, how they relate to prior law, and whether they meet established constitutional standards. The method proceeds by systematic identification, interpretation and synthesis of authoritative legal sources.
Primary sources will comprise the Online Safety Act 2023 and its explanatory notes; relevant secondary legislation and commencement regulations; Ofcom’s codes of practice and guidance; and the relevant case law of the domestic courts, the Court of Justice of the European Union (as interpretive context for retained principles) and the European Court of Human Rights. Secondary sources will include monographs, peer-reviewed journal articles, parliamentary materials and reputable regulatory and civil-society reports. Sources will be analysed using orthodox techniques of statutory interpretation and precedent, with particular care to distinguish binding authority from persuasive commentary.
The comparative element will juxtapose the UK regime with the EU Digital Services Act. The comparison is functional rather than merely descriptive: it asks how each instrument allocates responsibility and safeguards expression, in order to generate reform options for the UK framework. To manage scope, the comparison is confined to the treatment of hosting intermediaries and the balance struck with freedom of expression, excluding tangential matters such as advertising transparency. The methodology is justified on the basis that empirical fieldwork is unnecessary to answer questions that are, at their core, questions of legal doctrine and principle.
The dissertation will be organised into six substantive chapters:
The project is planned over a six-month full-time dissertation period, with overlapping phases to allow iterative refinement:
| Phase | Activity | Timeframe |
|---|---|---|
| 1 | Finalise proposal; complete systematic source identification and literature review | Month 1 |
| 2 | Draft Chapters 2 and 3 (prior settlement and OSA duties) | Months 2–3 |
| 3 | Draft Chapter 4 (enforcement) and Chapter 5 (comparative analysis) | Months 3–4 |
| 4 | Synthesis, draft Introduction and Conclusion; supervisory review | Month 5 |
| 5 | Revision, citation checking, proofreading and submission | Month 6 |
As a purely doctrinal and comparative study, the research involves no human participants, no personal data and no fieldwork, and therefore does not require ethical clearance of the kind associated with empirical projects. It will nonetheless be conducted to the ethical standards expected of legal scholarship. All sources will be accurately attributed in accordance with the institution’s academic-integrity policy, and the Harvard (Cite Them Right) referencing system will be applied consistently to avoid any risk of plagiarism. The researcher will represent legal authorities faithfully, distinguishing settled law from argument and acknowledging the provisional and evolving status of a regime whose codes and guidance continue to be published. Where the analysis touches on sensitive subject matter, such as child safety and illegal content, it will remain at the level of legal principle and will not reproduce or describe harmful material. Any limitations arising from the researcher’s own interpretive standpoint will be acknowledged transparently.
Three limitations are anticipated. First, the OSA regime is being implemented in phases, so some codes and guidance may be revised during the research period; the dissertation will state a clear “law as at” date and treat later developments as directions for future work. Secondly, the absence of a mature body of enforcement decisions means that assessment of Ofcom’s approach will be partly predictive, grounded in the statutory text and published policy rather than adjudicated practice. Thirdly, the comparative scope is deliberately narrow, confined to hosting liability and freedom of expression, which constrains the generality of the conclusions. These limitations are managed through transparent scoping rather than eliminated.
This proposal has outlined a coherent, doctrinally grounded project to evaluate one of the most significant reorientations of internet law in the United Kingdom. By tracing the movement from conditional immunity to systemic duties of care, scrutinising Ofcom’s enforcement architecture against rule-of-law standards, and testing the regime’s proportionality under Article 10 ECHR with comparative reference to the Digital Services Act, the dissertation aims to produce an original, rigorous and practically useful contribution to the emerging field of platform-governance law.
