Period of Responsibility meaning

Published by a LexisNexis Energy expert
What does Period of Responsibility mean?
In nuclear regulatory practice, the Period of Responsibility describes the span during which a nuclear site licensee remains responsible for the site and its licensed activities. In Great Britain (England & Wales and Scotland) under the Nuclear Installations Act 1965 and Office for Nuclear Regulation (ONR) guidance, it runs from the date a nuclear site licence is granted until the earlier of: (a) ONR’s written confirmation that the activities requiring the licence have ceased and the statutory “no danger” delicensing test has been met (whether or not the licence has already been surrendered or revoked); or (b) the grant of a new nuclear site licence for the same site. The expression is widely used in contracts, insurance and decommissioning documentation, rather than as a defined statutory term, but it tracks the GB delicensing framework. It is practically significant for continuing licence conditions, decommissioning controls, financial security/insurance and nuclear third‑party liability arrangements. Northern Ireland and Ireland do not operate the ONR nuclear site licensing regime. Usage there is typically descriptive or contractual by analogy, and must be read against local regulators and authorisations. Broad concepts of continuing responsibility may apply, but the GB ONR/“no danger” delicensing test does not.

UK quoted companies: annual report and accounts checklist for accounting periods from 1 January 2019 — Companies Act 2006, Listing Rules, DTRs, UK Corporate Governance Code, TCFD and energy/carbon disclosures

STOP PRESS: A major overhaul of the UK listing framework took effect on 29 July 2024, featuring the abolition of the premium and standard segments and the introduction of a single listing category for equity shares in commercial companies. The commercial companies category is strongly disclosure-led and sits beside other categories, including shell companies, secondary listing and closed ended investment fund categories. A new UK Listing Rules sourcebook commenced to deliver these reforms and the former Listing Rules sourcebook was withdrawn. For more information, see Practice Note: Reform of the UK listing regime—fundamentals. This fundamentals note describes the listing framework as it existed before 29 July 2024. The UK corporate reporting landscape has been influenced by Brexit. For further details see Brexit—accounts and reports. There have been certain amendments to the requirements of the Companies Act, the DTR and the Listing Rules for accounting periods starting on or after the close of the transitional period, although the impact is largely confined to definitions (eg the meaning of a regulated...

Delay in SIPP crystallisation was maladministration, but no liability for later LTA tax; Pensions Ombudsman applies Khan v Meadows to limit duty; overall tax improved

Original news Mr R (CAS-54306-K6B1) – 26 October 2024. Summary The Pensions Ombudsman dismissed a complaint concerning a scheme’s delay in crystallising pension benefits during a transfer, which the member argued caused higher-rate tax on future withdrawals and used more of his lifetime allowance than would otherwise have been necessary. Although the delay was held to be maladministration, responsibility for tax liabilities arising from subsequent crystallisation events did not fall on either the transferring or the receiving scheme. In addition, any loss he said he suffered was offset by growth in his fund over the period, which produced a larger tax-free lump sum and, in total, a lower tax bill. This decision is a reminder that a professional will not be accountable for every loss flowing from a breach of duty... What were the facts? ...

UK and EU regulation of unlicensed and off-label medicines: Specials, EAMS, NIMAR, compassionate use, supply, advertising, case law and liability

This Practice Note examines unlicensed medicines and the routes by which they can reach patients across the EU and the UK, such as via the UK Specials regime. It then looks at deploying authorised medicines beyond the scope of their licence (commonly termed off-label use). Lastly, the Practice Note addresses liability questions linked to using medicines without a licence. The UK’s regime governing unlicensed products is largely rooted in EU legislation. Numerous EU-derived principles and obligations remain in UK domestic law, save where particular measures provide otherwise. The Note surveys both EU and UK frameworks: analysis of EU requirements should be treated as relevant to the UK system unless distinct UK rules departing from EU law are set out separately. It also summarises pertinent EU case law; for guidance on the extent to which UK courts and tribunals are bound after the Brexit implementation period, see Q&A: Are UK courts and tribunals bound by decisions of the Court of Justice of the European Union post-Brexit?

Planning enforcement in England and Wales: breaches, investigations, discretion, time limits and immunity, notices and injunctions, appeals and criminal liability (including April 2024 reforms)

Breach of planning control and enforcement action Under the Town and Country Planning Act 1990 (TCPA 1990), any breach of planning control can be met with enforcement measures. For these purposes, a breach of planning control is understood to mean: undertaking development without the requisite planning permission — this presumes that an unauthorised operation or a material change of use has occurred which amounts to development within TCPA 1990, s 55, that such development requires planning permission, and that no permission has been secured When determining whether a breach of planning control has arisen in this context, the applicable guidance and case law on the meaning of ‘development’ must be applied; see Overview: Is planning permission required?...

Master trusts: authorisation, supervision, continuity and enforcement—PSA 2017, 2018 Regulations and TPR Code

The legislative framework The Pension Schemes Act 2017 The Pension Schemes Act 2017 (PSA 2017) is designed to strengthen safeguards for members of master trusts by tightening oversight of master trusts and addressing risk areas inherent in the master trust model when set beside other occupational pension schemes (such as profit-driven objectives, large cohorts of disengaged savers, and the potential jeopardy to pension pots if a master trust collapses). In summary, from 1 October 2018: master trusts must secure authorisation from the Pensions Regulator to operate as a master trust (with existing master trusts given until 31 March 2019 to submit an authorisation application, subject to any extension of the deadline granted by the Pensions Regulator). Five conditions must be met before the Pensions Regulator will grant authorisation—see: Authorisation criteria, below the Pensions Regulator has responsibility for the ongoing supervision of master trusts—see: Ongoing supervision and The Pensions Regulator’s proposed approach to supervision and enforcement, below master trusts must identify and manage ‘triggering...
