Law merchant meaning

What does Law merchant mean?
In practice, law merchant (lex mercatoria), sometimes called mercantile law, describes the body of mercantile customs and trade usages applied to commercial transactions and recognised by the courts in resolving trade disputes. It is not a single statute; it developed through merchant custom and case law and is now largely absorbed into the common law and key commercial statutes, including the Bills of Exchange Act 1882, the Sale of Goods Act 1979 (England & Wales, Scotland and Northern Ireland) / Sale of Goods Act 1893 (Ireland), and the Marine Insurance Act 1906. It informs areas such as negotiable instruments, bills of lading, carriage of goods, agency, sale of goods and letters of credit. Courts across the UK and Ireland admit evidence of trade usage to interpret contracts, imply terms or fill gaps, provided the custom is certain, reasonable, notorious and consistent with statute and established law. In cross-border practice, the term is also used more broadly to denote transnational commercial norms (for example INCOTERMS, UCP 600 and the UNIDROIT Principles). These instruments do not have force of law unless incorporated by contract or otherwise recognised. Usage and effect are broadly consistent across England & Wales, Scotland, Northern Ireland and Ireland.

UK competition law update: CMA provisionally finds SLC in GXO/Wincanton; CAT rejects Apple/Amazon CPO appeal; amended CPOs in MasterCard/Visa merchant service charge claims; upcoming dates

Mergers CMA issues interim report in GXO/Wincanton merger phase 2 investigation; provisionally finds competition concerns The CMA has published its interim report and interim notice on the completed takeover of Wincanton Plc (Wincanton) by GXO Logistics, Inc (GXO). GXO is the world’s largest contract logistics services company. Wincanton, a UK‑based business, also provides these services. Both organisations supply mainstream contract logistics services (CLS) to business customers in retail—such as groceries, fashion, and apparel—and in non‑retail—such as manufacturing and construction—sectors. In its phase 1 review, the CMA determined that the merger gives rise to a realistic prospect of an SLC, stemming from horizontal and unilateral effects in the provision of mainstream CLS across the UK...

FCA’s BNPL (DPC) regime: scope, CCA disapplication, Temporary Permissions Regime, SM&CR, financial promotions, section 75, and unresolved issues before UK rules commence by end‑2026

The government has also tabled draft legislation in Parliament. Once the statutory instrument (SI) is approved, BNPL products will be regulated 12 months after the SI is made. Lenders should expect the framework in force by end-2026. Although the policy trajectory is set, several key points remain unresolved. Key aspects of BNPL Regime Going forward, regulated BNPL agreements will be called regulated deferred payment credit agreements—deferred payment credit, or DPC. Scope In a boost for merchants, BNPL will be regulated only where a third-party lender is involved. An anti-avoidance measure tackles reseller-style models: where a lender buys the goods and resells them as the merchant, the deal is regulated, not exempt. Most merchants offering DPC will not need FCA authorisation as credit brokers. Unauthorised merchants must have financial promotions approved by an authorised firm—usually the third-party lender, if it holds the relevant permission. The broking exclusion does not currently extend to domestic premises suppliers; this remains under review after late-stage...

LNG tolling agreements: structure versus merchant model; tariff design, capacity/volumetric rights, lifting, ADP and allocation, SPAs alignment, bankability, liability and dispute resolution

Introduction The business model that supports a liquefied natural gas (LNG) project is crucial, as it shapes the project’s overall risk profile and, in turn, the form of financing required. The selection ultimately rests on several factors, such as risk appetite, fiscal and tax drivers, and the investor’s financing considerations, alongside whether they wish to invest in one or more segments of the LNG chain (for more on the LNG value chain, see Practice Note: LNG—an introduction). LNG projects can be configured in a range of ways: integrated/non-integrated merchant/tolling In an integrated arrangement, ownership is aligned across the whole LNG chain, from production through to liquefaction—that is, one or more investors holding the underlying upstream concession/PSC also hold the rights to the natural gas reserves...

UK merchant energy-from-waste contracts: procurement routes, funding, EPC/O&M and standard forms, risk allocation and key clauses, funder requirements, and Engie Fabricom guidance

EU ambitions to cut landfill disposal, together with advances in technology, spurred the roll-out of new waste infrastructure across the UK. Broadly, two principal contracting routes exist for such schemes: Waste Private Finance Initiative (PFI) and Public-Private Partnership (PPP) infrastructure contracts, which, from February 2025, are generally subject to the Procurement Act 2023. Existing PFI and Private Finance 2 (PF2) arrangements entered into before November 2018 continue to run Merchant waste infrastructure contracts A merchant contract is a binding agreement between a business (the merchant) and, commonly, an acquiring bank. Merchant waste schemes are those where the sponsor (or ‘acquiring bank’) is a private entity, for example the Green Investment Group. They may cover projects reliant on private, specialist feedstocks such as refuse derived fuel, commercial and industrial waste, and waste wood. This Practice Note concentrates on merchant waste infrastructure contracts. For details on waste PFI/PPP schemes, see Practice Note: Waste projects—waste PFI/PPP infrastructure projects.
