Parameters meaning

Published by a LexisNexis Energy expert
What does Parameters mean?
Parameters, in planning and infrastructure consenting practice, describe the defined limits of a proposed scheme—its form, scale, location, alignment and operational envelope—within which the detailed design may lawfully vary. Under a Development Consent Order (dco) for a Nationally Significant Infrastructure Project in England and Wales, parameters are fixed by the Order’s works descriptions, Works/Parameter Plans and Requirements, including any horizontal and vertical limits of deviation. They provide flexibility while constraining the project so that construction and operation remain within the consent. The term is not defined in statute; it is a descriptive concept used across planning and Environmental Impact Assessment (EIA) practice, and is closely associated with the rochdale envelope approach. Legally, the environmental assessment and any habitats assessment must evaluate the reasonable worst-case effects within the parameters. If the built scheme would exceed those limits, a change process or fresh consent is required. Comparable use of design parameters and limits of deviation is found in Scotland, Northern Ireland and Ireland for major consents (for example, Electricity Act section 36/37 consents, Transport and Works orders, marine licences and strategic infrastructure development). Across these jurisdictions, parameters must align with, and be justified by, the scope of the environmental assessment.

This checklist outlines the requirements an alternative investment fund manager (AIFM) must include in its remuneration policy under the AIFM Remuneration Code (the Code) in the Financial Conduct Authority (FCA) Handbook’s Senior Management Arrangements, Systems and Controls (SYSC) sourcebook (SYSC 19B), as well as the remuneration disclosures that belong in an alternative investment fund (AIF)’s annual report. What is the AIFM Remuneration Code (SYSC 19B)? The Code sits in SYSC 19B. It applies to a full-scope UK AIFM managing a UK AIF or a non-UK AIF. It covers pay and bonus for staff. It sets parameters for pay and bonus awards for specified Code staff. The Code comprises nine remuneration principles, set out in SYSC 19B.1.5 R to SYSC 19B.1.24 R. For guidance on each of these principles, see Practice Note: UK AIFMD—Remuneration Code—What are the AIFM Remuneration Code principles? The principles operate on a proportionate basis, meaning an AIFM must apply them in a manner suitable to its size, internal organisation and the complexity of its activities...

Record label claims against Suno and Udio: copyright infringement from AI training, overfitting as evidence, ‘fair use’ defences, and regulatory or licensing pathways

A number of record companies, among them Warner, Sony Music and Atlantic Records, have brought actions against Suno and Udio, issuing two lawsuits that accuse generative AI of producing ‘convincing imitations’ of existing tracks. Pre-action correspondence indicates that, as with other US disputes over generative AI, the companies’ core defence will rest on the claim that any copying amounted to fair use. How Suno and Udio allegedly hit the wrong note The claims assert that Suno (which has a deal to feature within Microsoft’s Copilot AI chatbot) and Udio ingest vast numbers of recordings, then refine and standardise them for use as training data, before extracting parameters from that dataset to build their AI models. When a user supplies a text prompt (for example, make a jazz song about New York), the service outputs one or more tracks—typically with lyrics—on the chosen theme. In a well-trained model, the goal is for results to reflect a generalisation of the training corpus. Here, however, it is alleged that the Suno...

EU AI Act GPAI Guidelines: scope, 10^23 FLOPs threshold, provider and modifier duties (including non‑EU), open‑source exemptions, code of practice, compute estimation and compliance timelines

On 18 July 2025, the Commission issued administrative guidance on the EU AI Act’s rules for GPAI models, designed to clarify scope, core concepts and how these interact with a related code of practice. The guidance sets out key legal terms to map the reach of the EU AI Act’s global partnership and artificial intelligence (GPAI) regime and pinpoint which businesses must comply. An initial draft was released in April 2025 to gather views from stakeholders. Following that consultation, the Commission’s AI Office outlined the principal revisions to EU Member States at a European AI Board meeting in late June 2025. The GPAI provisions will apply from 2 August 2025... Definition of GPAI models The guidance introduces a quantitative test to determine whether a model qualifies as a GPAI model—and is therefore within the AI Act’s remit—based on the computing power used for training. The benchmark, set in the early draft at 10²² floating-point operations per second, or FLOPs, has been increased to 10²³ FLOPs, aligning with the...

UK tax treatment of mid-completion unwinds of asset/business sales: corporation tax, VAT/TOGC, employment costs, SDLT/LBTT/LTT, set-off and termination payments

Business In periods of economic unpredictability (eg arising from high inflation and/or wider instability), organisations frequently cut costs. This can involve shedding contractual obligations and resolving legal disputes, but also purchasers seeking to withdraw from deals—for example, where a business or asset acquisition that seemed compelling to a buyer a couple of years or even months earlier becomes far less attractive. Yet unpicking an acquisition is rarely straightforward and, if not managed with care, can produce unforeseen tax consequences. This Practice Note outlines the tax issues that may emerge where a business or asset sale is unwound after signing and after certain assets and liabilities have already been transferred. It proceeds on the assumption that the buyer and seller are unconnected, are both UK tax resident, and are large corporate entities. For detail on the tax considerations relevant to undoing a share sale, see Practice Note: Unwinding a share sale—key tax consequences. For discussion of tax considerations relevant to an asset sale—many of which also apply when reversing an...

CJEU in Case C‑302/13 flyLAL: Competition damages are civil and commercial under Brussels I; Article 22(2) inapplicable; public policy not a bar to recognising Lithuanian interim measures

CASE HUB ARCHIVED This archived case hub sets out the position as at the judgment dated 23 October 2014 and is not being updated. See further: timeline commentary related/relevant cases Case facts Outline National reference from the Latvian Augstākās Tiesas Senāts to the Court of Justice, seeking a preliminary ruling under Article 267 TFEU to clarify several issues concerning the application of Regulation (EC) No 44/2001 (the Brussels Regulation) to a claim for competition damages — in particular, matters arising from a challenge, in Latvia, to the enforcement of interim measures ordered in Lithuania. On 23 October 2014, the Court of Justice held that a damages action for breach of competition law constitutes a ‘civil and commercial matter’ and thus falls within the ambit of the Brussels Regulation. The Brussels Regulation lays down the core parameters for identifying jurisdiction where claims involve parties situated in different Member States. In the context of competition litigation, the Brussels Regulation — alongside...
