    Major ECJ decision confirms when data may be anonymous in the hands of third parties

    On 4 September, the ECJ handed down a major and eagerly awaited decision on the scope of personal data, accepting the point that pseudonymised data may be anonymised in the hands of a third party.

    The ECJ’s approach is consistent with the approach of the UK data protection authority guidance, which we summarised earlier this year in an article, ‘What ICO guidance on anonymisation means for health and life sciences companies’.

    The decision will be widely welcomed as good news and a victory for common sense, particularly in the life sciences sector.

    Background

    The background to the case was the sharing of a dataset by the Single Resolution Board (SRB) with Deloitte, which had been tasked by SRB with carrying out a valuation of the effects of a resolution procedure on shareholders and creditors.

    SRB took a series of steps to protect the dataset shared with Deloitte, including applying pseudonymisation measures to the dataset. Deloitte had no access to the original database, and SRB retained a code which allowed it to reidentify the dataset. The dataset sent to Deloitte included an alphanumeric code but not the reidentification code. SRB did not include information in its privacy notice that Deloitte was a potential recipient of the personal data.

    Following this sharing, the European Data Protection Supervisor (EDPS) received five complaints from data subjects and found that the data was personal data (pseudonymised) because SRB retained the reidentification code.

    SRB did not look at the data from Deloitte’s perspective (i.e., in Deloitte’s hands). The view of the EDPS was that it was enough for the data to be personal data because SRB had the reidentification code.

    At the heart of the dispute was whether anonymisation should be an absolute or relative test. The EDPS adopted an absolute approach, and if the court had accepted EDPS’s view, this would mean it would never be possible for data to be anonymous if any person retained the code.

    The key legal question reviewed by the ECJ was whether the data relates to identified or identifiable persons. It was accepted that the persons were not identified, so the key point is whether the persons were identifiable.

    The court rejected the EDPS position here.

    Instead, the ECJ confirmed that, contrary to the opinion of the EDPS and EDPB, pseudonymised data may, depending on the circumstances of the case, ensure that persons are no longer identifiable. More importantly, the ECJ found that the fact that SRB held the reidentification code did not necessarily mean the data was personal data.

    Instead, it was possible to put oneself in Deloitte’s position to decide whether the data was identifiable. Here, the EDPS had not properly looked (as it should have done based on the Breyer case) at whether Deloitte had legal means available to it which could, in practice, enable it to access the additional information necessary to re-identify the persons.

    As the EDPS had not looked at Deloitte’s perspective, the court held that it was not possible for EDPS to conclude that the data was personal data.

    However, it is important to note that the court did agree with EDPS in one respect – and that is that SRB, as data controller,  had breached its transparency obligations because it did not tell data subjects that the data was being transmitted to Deloitte, regardless of whether such data was personal data from Deloitte’s perspective.

    What next?

    First, this ruling confirms that pseudonymisation may be recognised as an anonymisation technique in certain cases, which has always been challenged by several EU Data Protection Authorities.

    Second, it is very helpful to have a decision that says that an absolute approach to anonymisation is not always required – the court affirms the relative approach and says that the perspective of the recipient is the one to be considered, i.e., in assessing anonymisation, a “whose hands” test is relevant.

    However, it was accepted by the parties that the data was personal data in SRB’s hands. Hence, SRB needed to tell data subjects about who it was sending their data to. This raises interesting questions about the scope and nature of transparency and would indicate to an expansive transparency notice.

    Finally, given that the decision goes against the approach that had been advocated by data protection authorities, including in recent draft guidance, it is likely that the debate to shift to how to assess the re-identification risks in the hands of the recipient, and what is meant by “reasonable means” to re-identify. Interestingly, the ECJ included a reminder in the decision that the re-identification risk must be reasonably likely, noting that the court had previously decided that this risk is insignificant where identification of a data subject would be prohibited by law or impossible in practice, because it would involve a disproportionate effort in terms of time, cost, and labour (ECJ, 7 March 2024, OC v European Commission, C 479/22). It will be interesting to review the next steps and guidance issued by authorities.

    How can we help?

    Our expert teams provide extensive support to clients in developing anonymisation and pseudonymisation strategies and work with clients in negotiating and developing agreements for the re-use of personal data.

    We are working with clients to evaluate the impact of this decision on their data processing operations and adapting their privacy risk assessments and strategies in the context of pseudonymised environments.

    International News: Spotlight on ESG, Impact & Sustainability

    May 2023

    Read time: 4 min

    Key takeaways
    Überblick

    ESG is understood to be an acronym for “environmental, social and governance,” but the term can be challenging because it’s used to describe similar but distinct communities of practice, including corporate social responsibility, socially responsible investing, corporate sustainability and impact finance.

    In the 1980s, pension investor concerns for social and environmental issues evolved into what became known as socially responsible investing, which screened out investments that raised concerns over various human rights and environmental issues. This eventually spurred a corporate social responsibility (CSR) movement, pressuring corporations to take responsibility for the negative external impacts of their operations.

    A global sustainability movement also began in the 1980s seeking to reconcile economic development with the protection of social and environmental balance. This was adapted in the private sector into corporate sustainability, an intentional strategy to create long-term value through improved social and environmental impact. Corporate sustainability differs from CSR in that the latter is often not driven by strategic business imperatives.

    The investor perspective on financially material aspects of corporate sustainability coalesced under the term ESG, as famously used in a 2004 United Nations report issued by a coalition of 20 major financial institutions. The report included recommendations on integrating ESG value drivers into financial market research, analysis and investment. This was the birth of ESG, which has blossomed into an important asset class in worldwide financial markets.

    Although ESG has become politically fraught in the United States, internationally ESG regulation is becoming pervasive. This issue details these global developments, which, with the potential to more closely align business imperatives with social good, are fundamentally altering standards of corporate responsibility and investment decisions and analysis.

    Überblick

    After the post-pandemic boom enjoyed by the Life Sciences sector in 2021, the keyword going into 2023 is uncertainty. On the investment side, it’s shifted dramatically from a seller’s to a buyer’s market, and uncertainty is impacting every aspect of business, including the new transition timelines announced for the EU and UK medical device regimes, and protection of sensitive patient and commercial data owing to the stratospheric rise in cybersecurity insurance premiums.

    Never has it been more important for businesses to manage the issues that are within their control, such as ensuring robust compliance and proactively preparing for dispute resolution.

    Some extremely positive messages did, however, emerge from panel discussions at McDermott’s Health and Private Equity (HPE) Europe 2022 and European Life Sciences and Healthcare Symposium. Businesses that deliver excellence, whether that’s in patient care or with good scientific assets or an advanced product, are likely to weather the current challenges. In addition, the launch in Spring 2023 of the Unified Patent Court and the European patent with unitary effect will revolutionise the way patents are enforced in Europe, finally delivering the option to enforce, attack, and defend a patent before a single court.

    Überblick

    In line with the evolution of the economy and the ongoing growth of online business and global trade, we’re seeing a corresponding increase in competition regulation and a rise in enforcement across all authorities.

    The growth of the online economy has triggered the US Federal Trade Commission’s (FTC) update of its 20 year old .com Disclosures: How to Make Effective Disclosures in Digital Advertising guide, and the development of an analytical framework for all digital distribution across the European Union. In just one seismic shift under the new EU Vertical Block Exemption Regulation 2022/720, dual-pricing, i.e., setting different wholesale prices for online/offline sales by the same distributor, is no longer considered a hardcore restriction unless its purpose is to prevent the effective use of the internet to sell the goods or services.

    In the United States, there is an increased focus on anticompetitive mergers and acquisitions (M&A). The Biden Administration, the Department of Justice Antitrust Division, and the FTC have all stated that the regulatory landscape needs to be reshaped to better reflect dynamic markets, and their priority is the aggressive pursuit of litigation against offending parties rather than the granting of consent decrees. The tendency to “sin first and beg forgiveness later” will emphatically no longer work, as a recent French gun-jumping case demonstrates.

    Both the United States and the European Union have also turned their attention to investigating wage fixing and no-poach labour market violations that are not connected with M&A or business collaborations. It’s clear that competition/antitrust authorities are determined to expand their remit.

    It is always the case that businesses must keep up with changes to tax rules, but never have tax rules had to pay equally close attention to changes in business. The evolution of technology and the internet age have driven seismic shifts in the ways companies operate, and presented new challenges for tax regimes.

    The long-awaited Organisation for Economic Co-operation and Development (OECD)/G20 Global Anti-Base Erosion Model Rules, intended to address perceived challenges to longstanding international taxation principles by the increasing digitalisation of the economy, are coming closer to becoming a reality with the agreement by 137 OECD/G20 countries and jurisdictions to join the official statement of the Two-Pillar Solution. But we’re still not there yet. Similarly, despite the Non Fungible Token (NFT) market being worth US$21 billion, the US Internal Revenue Service (IRS) still hasn’t explicitly stated how NFTs will be taxed.

    Without clear rules and guidance, businesses need to be highly vigilant. The continuing trend of working outside the office means international companies must ensure their remote workforce doesn’t inadvertently trigger tax liabilities by creating a permanent establishment or permanent representative; and trustees must undertake regular reviews to ensure changes within the trust don’t generate new taxable events. In addition, companies need to be aware of how expected changes to tax laws may be more aggressive than anticipated, such as the withdrawal by the US IRS of certain foreign tax credits.

    This is a phenomenally interesting time to be a Private Equity investor. The dramatic shifts in focus caused by the global COVID-19 pandemic, the increasing challenge of climate change, and the growing emphasis on corporate governance, have converged to create a perfect storm of opportunity and demand for investment.

    Nowhere is this more apparent than in the healthcare and life sciences sectors, which are seeing unprecedented expansion as a result of the existing, pre-pandemic move towards a new world of healthcare delivery, and the reinforcement of healthcare services as a major priority across the globe. Our HPE New York 2021 panel of experts provide insight on how the most successful funds are maximising the current opportunities.

    Running a close second, the shift towards renewable energy has opened up avenues for investment that might not be immediately obvious: the upstream oil and gas industry. Demand for oil continues to surge, but the current importance of environmental, social, and governance considerations, has rendered hydrocarbons unattractive for public investment. PE and private wealth look poised to step into the void.

    Of course, these opportunities also create challenges and potential pitfalls for over-enthusiastic but unprepared investors who may fear they are missing out on the next big thing. A clear-eyed understanding of risk, and a strong commitment to mitigating it, have never been more valuable.

    In a joint statement issued in June this year, the G7 nations pledged to support a “green revolution that creates jobs, cuts emissions and seeks to limit the rise in global temperatures to 1.5 degrees,” and committed to “net zero no later than 2050, halving our collective emissions over the two decades to 2030.”

    The renewable energy sector is at the front of this green revolution. The demands of the transition to net zero are causing unprecedented impacts on fields as diverse as competition law and employee unionization, are being granted major significance in once-in-a-generation national projects such as the $2.3 Trillion American Jobs Infrastructure Plan, or are the focus of multi-national collaborations such as the Association of Southeast Asian Nations power grid system.

    Renewable energy is no longer considered a niche investment and there are myriad opportunities in new technologies or the repurposing of old technology, such as using green ammonia to transport hydrogen.

    But the old ways aren’t dead yet, and our current reliance on oil means there is still a need for astute investment in this sector to make hydrocarbons cleaner and more efficient until net zero is achieved.

    The global healthcare industry has had the most challenging year in living memory. But 2021 is a new year. Alongside new challenges, such as whether or not healthcare employers can or should make COVID-19 vaccines mandatory for employees, and the uncertainty surrounding the transfer of European health data post-Schrems II, there are also many new opportunities.

    Sovereign Wealth Funds are increasingly seeing the health sector as an attractive investment market, and Social Impact Bonds have emerged as an excellent financing option for development projects that might otherwise find it hard to attract initial funding.

    Healthcare companies still, of course, need to pay close attention to their commercial operations. As the market evolves to meet the new normal of an increasingly online and app-centric world, the need for robust agreements with software developers becomes ever more important. And the sector will always be the target of investigations into excessive pricing, and subject to developments relating to key tools such as Supplementary Protection Certificates. But the time has come to be cautiously optimistic and to look to the future of healthcare

    As we move into the next phase of the Coronavirus (COVID-19) pandemic, the test, track and trace approach being adopted by governments is generating myriad data privacy concerns. Added to this are the challenges created by new privacy laws in California, the end of the Brexit transition period, and the recent judgement in Schrems II that affects the US Privacy Shield mechanism. There has never been a more pressing need for robust global privacy and cybersecurity advice.

    Although the pandemic continues to impact global business, creative thinkers are identifying solutions to economic distress and are examining the viability of material adverse effect clauses in their markets. And, of course, developments unrelated to the pandemic, such as the forthcoming EU Whistleblower Directive and the Federal Trade Commission’s focus on non-compete provisions in transaction agreements, continue to challenge companies.

    We explore all these issues and more, in our latest International News.
