Additional Protocol meaning

Published by a LexisNexis Energy expert
What does Additional Protocol mean?
In practice, an Additional Protocol is a supplementary agreement to a State’s iaea safeguards agreement that widens the IAEA’s access to information and sites to verify the peaceful use of nuclear material. It is a treaty instrument developed under the Non-Proliferation Treaty framework (based on the Model Additional Protocol, INFCIRC/540), rather than a term defined in UK or Irish statute, though it is implemented through domestic safeguards and reporting requirements. Key features include expanded declarations (covering nuclear fuel-cycle–related R&D, manufacturing, and certain imports/exports), complementary access for IAEA inspectors at short notice, and the possibility of environmental sampling. Its purpose is to enhance the efficiency and strengthen the effectiveness of IAEA safeguards. Across England & Wales, Scotland, Northern Ireland and Ireland, usage is consistent. The UK now operates under a UK–IAEA safeguards agreement and Additional Protocol that took effect on 31 December 2020 following withdrawal from Euratom. Ireland is covered by the EU–IAEA (Euratom) safeguards agreement and Additional Protocol, implemented domestically. Practically, counsel encounter the Additional Protocol in nuclear safeguards compliance, licensing, and export control, and when advising operators, suppliers and research bodies on reporting and inspection obligations.

Seller’s solicitor checklist for selling a registered freehold residential property—vacant possession or subject to tenancies (England and Wales): from initial instructions to post-completion

Use this checklist when representing the seller in the disposal of a registered freehold residential property, whether offered with vacant possession or burdened by a lease or multiple leases. It is not comprehensive and will not address every eventuality in every transaction. You should always consider if there are additional matters that require attention. It does not purport to be a complete guide for every case. Preliminary matters Have you taken instructions from the client? Robust due diligence and effective transaction management depend on a clear grasp of the seller’s objectives and the proposed sale terms. Obtain full instructions, and clarify any elements of your brief that are unclear or out of the ordinary. Consider whether further specialist input is required; for example, planning advice where completion is conditional upon planning permission being secured. The table below sets out some of the principal points on which instructions should be obtained at the outset. This list is not comprehensive, and you may need to request information about additional...

English law LMA par secondary loan trades: pre-trade due diligence and settlement guide (transfer criteria, RFR/IBOR interest and DSC, KYC, tax, regulatory, sub-participations, BISO)

STOP PRESS The Loan Market Association (LMA) has released refreshed editions of the standard terms and conditions for Par and Distressed Trade Transactions, the complete set of Funded Participation and Risk Participation Agreements, and the Secondary Debt Trading Documentation User Guide, with effect from 17 March 2026. The changes remove LIBOR references, update IBOR rate definitions and the Target2 definition, and revise ERISA representations to incorporate additional exemptions to the prohibited transaction rules under ERISA and the US Internal Revenue Code. The revised documentation is available exclusively to LMA members, accessible via the LMA’s Documentation Hub. These publications are updated versions issued by the LMA. Summary A core principle of trading under the LMA protocol is that ‘Trade is a Trade’; i.e. once a trade is struck—including an oral contract agreed by telephone—it is binding, and subsequent developments, even if adverse to one or both parties, do not entitle either party to cancel or ‘break’ the trade. By way of example, a failure to secure consent for...

RTA Small Claims Protocol (England and Wales): Scope, Exclusions, Portal Procedure, Whiplash Tariff (2025), Mixed Injury Damages, Evidence, Medical Reports, Offers and Liability

The Pre-Action Protocol for Personal Injury Claims Below the Small Claims Limit in Road Traffic Accidents (RTA Small Claims Protocol) is engaged for collisions taking place on or after 31 May 2021. For RTA personal injury matters, the small claims track cap for general damages—covering pain, suffering and loss of amenity (PSLA)—now stands at £5,000, save for exceptions in CPR 26.10 and CPR 26.11. The protocol is intended for situations where a person has sustained injuries in a road traffic accident (including, though not confined to, whiplash) and wishes to pursue compensation, provided the sum claimed for the injury does not exceed £5,000 and the value of the case does not exceed £10,000. It operates for claimants pursuing personal injury compensation from RTAs within these injury and overall value limits. For additional guidance on using the RTA Small Claims Protocol, consult Practice Note: The road traffic accident small claims protocol...

Residential conveyancing pre-contract enquiries in England and Wales: duties of disclosure, standard and additional enquiries, reliance and misrepresentation, and DMCCA 2024 consumer protection considerations

This Practice Note examines enquiries before contract—also referred to as pre-contract enquiries, preliminary enquiries or standard enquiries—within residential conveyancing transactions. It proceeds on the basis that the parties have adopted the Law Society Conveyancing Protocol (2019) (the Protocol) and that the buyer’s conveyancer is additionally acting for a lender in line with the UK Finance Mortgage Lenders’ Handbook (the UKFML Handbook) or the Building Societies Association Mortgage Instructions (the BSA Instructions). See Practice Notes: The Law Society’s Conveyancing Protocol and Lenders' instructions—the UK Finance Mortgage Lenders' Handbook and the Building Societies Association Mortgage Instructions. Why raise enquiries? At common law, the guiding doctrine is ‘caveat emptor’—‘let the buyer beware’—so a seller has only a limited duty to disclose information about the property. It is principally for the buyer to ensure they understand what they are purchasing, including the nature of the property and any rights or liabilities that may attach to it. Accordingly, a buyer’s conveyancer raises enquiries before contract to secure information about the property...

Acceleration in Construction Projects: Express and Implied Measures, JCT/NEC Processes, Pricing and Bonuses, Extensions of Time, Liquidated Damages Risk and Record-Keeping

What is acceleration? In construction law, acceleration is commonly taken to mean adopting steps to increase the pace of the works so completion occurs sooner than it otherwise would. However, there is no settled legal definition of the term. In Ascon v Alfred McAlpine, the court remarked that ‘acceleration’ is often bandied about as if it were a precise term of art, yet nothing persuaded the judge that this was so. The root idea behind the metaphor is, no doubt, that of increasing speed and, in the context of a construction contract, finishing earlier than planned. On that basis, ‘accelerative measures’ are actions taken—assumed to be at increased expense—with a view to achieving that aim and bringing completion forward. The Society of Construction Law’s Delay and Disruption Protocol (SCL Protocol) describes acceleration as the application of additional resources or alternative construction sequences or methodologies, seeking to realise the planned scope of work in a shorter time than planned, or the execution of additional scope of work within the...
