Charming Betsy: Balancing Domestic Laws & International Obligations

Introduction

How should courts interpret domestic laws when they appear to contradict international obligations?

This question was answered over two centuries ago in Murray v. The Schooner Charming Betsy (1804), a landmark U.S. Supreme Court case that established the Charming Betsy doctrine.

Chief Justice John Marshall laid down the principle:

“An act of Congress ought never to be construed to violate the law of nations if any other possible construction remains.”

This doctrine remains highly relevant today, influencing cases related to trade, human rights, environmental law, and digital governance. It ensures that domestic statutes align with international commitments whenever possible, reinforcing the principle of pacta sunt servanda (agreements must be kept).

Background of the Charming Betsy Case 🏛️

During the Quasi-War (1798–1800) between the United States and France, Congress passed the Non-Intercourse Act of 1800, restricting U.S. trade with France. The Charming Betsy, a U.S.-built vessel sold to a Danish citizen, was seized by a U.S. naval ship for allegedly violating this law.

Chief Justice Marshall ruled that U.S. laws should be interpreted in a way that avoids violating international law, unless Congress explicitly states otherwise. This protected foreign trade relations and ensured legal harmony between U.S. and international obligations.

The Charming Betsy Doctrine: A Guiding Principle 📜

The Charming Betsy doctrine serves as a rule of statutory interpretation, requiring courts to align domestic laws with international obligations whenever possible. It applies broadly across:

✅ Trade & Economic Sanctions – Ensuring U.S. trade laws comply with World Trade Organization (WTO) rules.

✅ Environmental Protection – Interpreting domestic statutes to uphold international climate agreements.

✅ Human Rights & Immigration – Preserving refugee protections under United Nations treaties.

✅ Digital Governance & Cybersecurity – Harmonizing U.S. cyber laws with international data protection standards.

Modern Applications of the Charming Betsy Doctrine ⚖️🌍

Despite originating over 200 years ago, this doctrine still influences contemporary legal decisions.

1️⃣ Trump v. Sierra Club (2020) – Environmental Law 🌱

The Supreme Court considered whether military funds could be diverted to construct a border wall. Opponents cited international environmental obligations protecting migratory species. Courts referenced Charming Betsy in discussing how statutes should align with global treaties.

2️⃣ Nestlé USA, Inc. v. Doe (2021) – Corporate Human Rights Accountability 🤝

This case addressed corporate liability for child slavery under the Alien Tort Statute (ATS). The dissent referenced Charming Betsy, arguing that U.S. laws should be interpreted to uphold international human rights obligations.

3️⃣ Twitter, Inc. v. Taamneh (2023) – Digital Regulation & Global Standards 📡

The Supreme Court examined whether social media companies could be held liable for terrorist content under U.S. law. The ruling engaged with international free speech principles, with Charming Betsy cited to prevent conflicts with global human rights norms.

Criticism and Limitations of the Charming Betsy Doctrine ⚠️

While the doctrine is valuable, it is not without challenges:

1️⃣ Congressional Intent vs. Judicial Interpretation

Critics argue that courts may override Congress by prioritizing international law. If Congress explicitly legislates against international norms, should courts still attempt to align laws with treaties?

🔹 Example: Medellín v. Texas (2008) 🇺🇸
The Supreme Court ruled that a binding International Court of Justice (ICJ) decision was not automatically enforceable in U.S. courts without Congressional action. This case demonstrated that Charming Betsy has limits when Congress acts explicitly.

2️⃣ Conflict with National Sovereignty 🏛️

Some scholars argue that Charming Betsy weakens national sovereignty, forcing courts to apply international norms even when domestic policy dictates otherwise.

🔹 Example: Bond v. United States (2014)
The Supreme Court refused to interpret a chemical weapons treaty in a way that expanded federal authority over state jurisdiction, signaling a limit on Charming Betsy when affecting domestic governance.

3️⃣ Selective & Inconsistent Application 📜

While courts invoke Charming Betsy in trade and environmental cases, they often ignore it in national security or immigration cases.

🔹 Example: Trump v. Hawaii (2018) – Travel Ban Case ✈️*
The Supreme Court upheld the Trump administration’s travel ban, despite international non-discrimination norms. The Court did not apply Charming Betsy, showing selective enforcement based on political considerations.

4️⃣ Difficulty in Balancing Conflicting International Norms 🌍

With globalized legal frameworks, treaties sometimes contradict one another. Courts struggle to apply Charming Betsy when multiple international norms are in play.

🔹 Example: Kirtsaeng v. John Wiley & Sons, Inc. (2013) – Copyright & Free Trade Dispute 📖
The Supreme Court balanced U.S. copyright law with international free trade principles, showing how Charming Betsy does not always provide clear guidance.

Conclusion: A Doctrine for a Globalized World 🌎⚖️

The Charming Betsy doctrine remains a cornerstone of international legal interpretation, ensuring that domestic laws align with global obligations. However, its selective application, conflict with sovereignty, and judicial limitations raise concerns about its consistency and enforceability.
