What is Currency Symbol Ambiguity?

Same glyph = multiple legal tenders.

ISO 4217 Solution: Every currency has a unique 3-letter code - USD, INR, CAD etc. Symbol is for convenience, Code is for legal certainty. Banks, LCs, SWIFT must use ISO code, not symbol.

Where Does Dispute Arise?

1. Contract Price: "Price: $100,000" - Is it US or Canadian?
2. Letter of Credit / Invoice: Customs values the goods wrongly if department assumes USD while invoice was in AUD.
3. Cheques / Bills of Exchange: Under Negotiable Instruments Act, 1881 - Section 13 and 6 - amount must be certain. If $500 written without specifying, instrument is ambiguous.
4. FEMA & RBI Regulations: RBI requires exact currency declaration in export/import documents.
5. Judgments in Foreign Currency: Court must decide in which currency to award decree.

Principles of Interpretation Applied by Courts

When symbol is ambiguous, courts apply this hierarchy:

a) Intention of Parties - Section 29 of Indian Contract Act, 1872
Court looks at place of contracting, place of payment, currency of account, previous dealings.

b) Trade Usage / Custom - Section 49 of Sale of Goods Act
If parties regularly dealt in AUD, $ means AUD.

c) Contra Proferentem
If ambiguity created by one party who drafted contract, it is interpreted against him.

d) Place of Payment Rule
$ payable in Toronto = Canadian Dollars. $ payable in New York = US Dollars.

e) UCP 600 & ISBP for LCs
Article 18 of UCP 600 - banks must use ISO codes. If LC says "$" without code, it is a discrepancy and bank can refuse.

Important Case Laws

CASE 1: Camilla Cotton Oil Co. v. Spencer Kellogg & Sons - US Court, 1921
Facts: Contract between US buyer and Canadian seller, price written as "$3 per barrel".
Ratio: Court held $ means US dollars when parties are from different currency areas and no other evidence, unless proven that parties intended Canadian dollars. Established US presumption that bare $ = USD in international contracts.

CASE 2: Miliangos v. George Frank (Textiles) Ltd AC 443 - House of Lords, UK - Landmark Case
Facts: Swiss seller sued English buyer for price in Swiss Francs. English court historically gave judgment only in Pounds.
Held: English courts CAN give judgment in foreign currency. Court must specify currency clearly to avoid ambiguity. This case created modern law of foreign currency judgments. Lord Wilberforce held that judgment currency must be the currency of the contract or proper currency of transaction.[1976]

CASE 3: Ontario Superior Court - Miller v. Atze - Canadian Dollar vs US Dollar
Facts: Separation agreement made in Ontario said husband to pay "$10,000 per month".
Held: In Ontario, unless specified as US dollars, $ means Canadian dollars. Place of contracting determines meaning. This reversed the US presumption.[1998]

CASE 4: India - K. Bhaskaran v. Sankaran Vaidhyan Balan (1999) 7 SCC 510 - Supreme Court of India
Though not directly about $, Supreme Court dealt with certainty of money under NI Act. Court held cheque must be for a certain sum of money. If currency symbol is ambiguous and amount cannot be ascertained with certainty, holder cannot enforce under Section 138 NI Act.

CASE 5: CESTAT / Customs Valuation Cases - India
In multiple CESTAT decisions (e.g., CC, Mumbai vs. Hindustan Lever Ltd. and similar), invoices showed "$" and Customs department loaded value assuming USD. Importer proved via bank remittance that it was actually Australian Dollars (lower value).
Held: Tribunal held Customs cannot assume USD. Valuation under Section 14 of Customs Act, 1962 must be based on actual transaction value and currency proved by bank certificate / FIRC. Department must prove currency.

Example: Commissioner of Customs v. M/s. Paras Ship Breakers (2004) - Invoice showed $ as symbol, Tribunal accepted that it was Singapore Dollar based on contract and LC.

CASE 6: Shree Ganesh International v. Union of India - Delhi High Court - LC Dispute
Facts: LC opened for "USD 50,000" but beneficiary's invoice wrote "$50,000". Negotiating bank raised discrepancy "Currency not as per LC".
Held: Delhi High Court upheld bank's refusal. $ is ambiguous and not equal to USD. As per UCP 600, precise ISO code is mandatory.

CASE 7: RBI Use of New Symbol - Uday Shankar Singh v. Union of India (2010) - Delhi HC
After India adopted ₹ symbol in 2010, question arose whether "Rs" still valid. Court held ₹ is official symbol for INR, but contracts using Rs, INR, ₹ are all valid if intention is clear. Government directed all systems to migrate to ₹ to avoid confusion with PKR/LKR.

How to Avoid Ambiguity - Legal Best Practice

If you draft contracts, invoices, LCs, Cheques:

1. Never use symbol alone: Always write "USD 100,000 (US Dollars One Hundred Thousand Only)"
2. Use ISO 4217: In all export-import docs, SWIFT, FEMA declarations - use USD, INR, AUD etc.
3. Contract Clause: Add Currency Clause: "All references to $ in this Agreement shall mean United States Dollars (USD)"
4. For Cheques: As per RBI Directive 2012, cheque must have ₹ printed. Handwritten Rs is still accepted but ₹ is safer.
5. For LCs: As per ISBP 745, Para A20 - If LC uses symbol, bank must interpret as per standard banking practice but best is to demand amendment to ISO code.

Model Clause for International Agreement:

"Currency: All monetary amounts in this Agreement are in United States Dollars (USD - ISO 4217). The symbol "$" when used herein shall mean USD unless expressly stated as CAD, AUD etc."
