“Because of the pure breadth and depth of black letter law research and practical guidance that LexisNexis provides, we don't have to rely on counsel as much as perhaps firms that don't use LexisNexis.”

Transparency Directive meaning

What does Transparency Directive mean?
In practice, this term refers to the EU regime that sets minimum ongoing disclosure and periodic reporting obligations for issuers whose securities are admitted to trading on a regulated market (for example, the Main Market of the London Stock Exchange or Euronext Dublin). It is defined in legislation: Directive 2004/109/EC (the Transparency Directive), as amended by Directive 2013/50/EU, which itself amended Directive 2001/34/EC. Key features include: annual and half‑yearly financial reporting; disclosure of major holdings of voting rights; rules on the timing, format, language, dissemination and storage of “regulated information”; identification of an issuer’s home Member State; and equivalence provisions for third‑country issuers. The regime underpins market transparency and investor protection and is a cornerstone of listed company disclosure compliance across the EEA. UK position: following Brexit, the Directive no longer applies directly, but its substance has been onshored through FSMA and the FCA’s Disclosure Guidance and Transparency Rules (notably DTR 4 and DTR 5), which apply uniformly across England & Wales, Scotland and Northern Ireland, with some UK‑specific calibrations. Ireland: the Transparency Directive continues to apply as EU law and is implemented through national regulations overseen by the Central Bank of Ireland. Usage of the term is broadly consistent across the...

Participant Information Sheets in UK clinical research: legal, ethical and UK GDPR compliance checklist for CTIMPs and non-CTIMPs

Checklist This Checklist sets out the practical actions for creating, drafting and quality-checking a Participant Information Sheet (PIS) for UK clinical research. It describes what the PIS is for and how it works, and gives hands-on advice on the essential components, addressing content and presentation alongside layout, format and style. The Checklist also explains how the PIS should meet obligations under UK data protection law, including the transparency duties in the United Kingdom General Data Protection Regulation, Assimilated Regulation (EU) 2016/679 (UK GDPR). It is suitable for any study involving human participants, with particular emphasis on clinical trials of investigational medicinal products (CTIMPs). A clinical trial is a study in human subjects intended to identify or confirm the effects of an adverse reaction to a medicinal product. In the UK, such trials are governed by the Medicines for Human Use (Clinical Trials) Regulations 2004 (MHU(CT)R 2004), SI 2004/1031, which transposed EU Directive 2001/20/EC, the Clinical Trial Directive (CTD), into domestic law. These rules create a legal framework designed to...

Nanotechnology and nanomaterials regulation in the UK and EU: REACH nanoforms, 2022 definition, sectoral regimes, and post-Brexit divergence under the Windsor Framework

Nanotechnology—opportunities and risks Nanotechnology deals with the fabrication and application of matter at ultra-small scales. Nanomaterials are quantified in nanometres (nm) and can be many thousands of times thinner than a human hair; a single hair measures around 80,000 to 100,000 nm across. At these dimensions, substances display properties that diverge from those of the same material in bulk form, enabling novel uses while potentially introducing distinct hazards. Current adopters span key fields and wider industries: Biomedicine, electronics and energy Cosmetics, defence, automotive and agriculture Applications range from high-volume commodities, for example carbon black in car tyres, through to specialised, low-volume technologies. Cosmetics commonly incorporate nano titanium dioxide and zinc oxide to deliver functions such as UV filtering, while gold and silver nanoparticles feature in medical diagnostic tools. A 2023 report put the global nanotechnology market at US$69.15bn in 2022, projecting expansion to US$248.56bn by 2030. The European Commission regards micro/nano—electronics and photonics as a Key Enabling Technology that should be...

Precedent: Short-form Privacy Policy for UK General Commercial Organisations (UK GDPR, DPA 2018, PECR) with DUAA 2025 Implementation Notes

STOP PRESS: On 19 June 2025, the Data (Use and Access) Bill secured Royal Assent, transforming into the Data (Use and Access) Act 2025 (DUAA 2025), with partial commencement on that very same day. A number of DUAA 2025 provisions, covering areas like handling data subject access requests and granting powers to make additional regulations, took effect immediately on 19 June 2025. Other related provisions, relating to Information Commissioner notices and certain aspects of law enforcement processing, commenced on 19 August 2025 (being two months from the date of Royal Assent). The majority of DUAA 2025’s measures still require further regulations, in the form of statutory instruments, to be made in order to bring them fully into force. Parts 5 and 6 of DUAA 2025 serve to amend several facets of data protection and ePrivacy law in the UK, including the United Kingdom General Data Protection Regulation, Assimilated Regulation (EU) 2016/679 (UK GDPR), the Data Protection Act 2018, and the Privacy and Electronic Communications (EC Directive) Regulations 2003, SI...
