Sources of Indian Commercial Law
Where does Indian Commercial Law actually come from? It is not the invention of any single body — it has grown out of four broad, recognised sources.
1. Legislation (Statutes/Acts). The primary and most authoritative source is law formally enacted by Parliament (or, before Independence, by the British Indian legislature, much of which was itself modelled on English mercantile law). Most of Commercial Law as it is studied today is codified in specific Acts — the Indian Contract Act, 1872, the Sale of Goods Act, 1930, the Indian Partnership Act, 1932, the Negotiable Instruments Act, 1881, and the Companies Act, 2013 are the central pillars, each of which becomes its own unit later in this two-year course.
2. Case Law (Judicial Precedent). Courts, particularly the Supreme Court and the High Courts, interpret and apply these Acts to real disputes, and their reasoned decisions become binding precedent for similar future cases (the doctrine of stare decisis — "to stand by things decided"). Where a statute is silent or ambiguous, judicial decisions fill the gap and effectively become part of the operative law on that point.
3. Custom. Certain long-established, reasonable, and consistently followed practices of a particular locality or community — provided they are certain, continuous, and not opposed to any statute or public policy — are recognised by courts as legally binding, even without being written into any Act.
4. Mercantile Usage. Distinct from a general "custom," mercantile usage refers to well-established, uniform practices followed specifically within a particular trade or business. Where a written contract is silent on a point, an established mercantile usage of that trade is read INTO the contract by the courts — unless the parties have expressly excluded it. This is why the Sale of Goods Act, studied later in this course, repeatedly says a rule applies "unless a different intention appears from the terms of the contract, the conduct of the parties, or the usages of trade."
Together, these four sources — Legislation, Case Law, Custom, and Mercantile Usage — form the complete foundation from which every rule studied in the rest of this Commercial Law course is drawn.
The four sources of Indian Commercial Law
- Legislation — Acts of Parliament (Contract Act 1872, Sale of Goods Act 1930, Partnership Act 1932, Negotiable Instruments Act 1881, Companies Act 2013).
- Case Law — binding judicial precedent from the Supreme Court/High Courts.
- Custom — long-established, certain, and reasonable local practices.
- Mercantile Usage — established trade-specific commercial practices, read into a contract unless expressly excluded.
