Legal professionals around the world often use the terms 'hard law' and 'soft law' to describe certain international legal texts. If you're delving into international law, whether for educational purposes or to better understand global events, it can be challenging to distinguish between hard law and soft law. It becomes even more complex as international law is founded on the principle of sovereignty of independent member states, meaning no international agreement is entirely rigid or entirely flexible. When reading the provisions of a treaty or other international agreements, certain fundamental elements can help you identify the degree of rigidity or flexibility of the text. Recognizing these elements will assist you in better understanding how international law regulates the actions of each country and the relationships between countries.
Steps
Identify the legal obligations

- Treaties are a prime example of agreements that are automatically considered hard law. When countries ratify a treaty, if domestic laws conflict with the treaty's content, those countries are obligated to amend their laws to align with the treaty.
- The United States views treaties as legally binding both internationally and domestically. After the Senate ratifies a treaty, the U.S. Congress will pass the necessary federal legislation to comply with the treaty's provisions.
- Resolutions of the United Nations Security Council bind all UN member states legally, based on the Council's authority under Article 25 of the UN Charter.

- International agreements are often designed to promote the interests of the signatory nations, so these countries typically have little incentive to violate the agreement. As a result, the agreement itself might not include specific terms that enforce legal obligations.
- Sometimes, treaties related to human rights or standard principles are referred to as 'conventions.' These agreements bind member states legally, much like treaties, though they may not specify the core obligations for enforcement.
- A country may sign a treaty but reserve certain provisions within it. These reservations limit the country's legal obligations regarding the provisions it has not accepted.
- International agreements that do not legally bind member countries are considered soft law. These documents often present conditions or escape clauses that allow signatory nations to make general commitments to certain principles while maintaining their sovereignty and independence.

- Some international legal documents may bind certain countries legally, but not others. For example, a ruling by the European Court of Human Rights on a specific case is only legally binding on the countries involved in that case. However, the ruling may change the perspective of another court or an international organization when handling a similar case.
- Soft law can outline broad principles that are agreed upon by many countries, even if these countries disagree on specific provisions. These soft agreements often form the foundation for future hard law agreements.
- A country may agree to the principles of a treaty but not be able to complete the ratification process. However, it can still pass domestic legislation that aligns with the treaty's viewpoints.
Analyze the language used

- Describing commitments with precise language ensures that member states fully understand the limits of their obligations, avoiding self-interested actions or opportunism in the future.
- Hard law also uses exact wording when outlining conditions or exceptions to obligations. This helps prevent a country from exploiting legal loopholes to undermine the treaty's objectives.

- Hard law typically includes requirements or obligations that member states must adhere to. It often specifies penalties or other forms of punishment for countries that fail to meet their obligations under the agreement by a certain deadline.
- In contrast, soft law usually lists actions that member states may take within the scope of the agreement, without requiring them to fulfill specific obligations.
- If an agreement discusses the commitment of member states to investigate an issue or conduct a feasibility study within a certain timeframe but does not require any specific actions, those clauses are soft law provisions.

- Soft law typically employs broad terms, allowing readers to interpret the text in various ways, while hard law includes general descriptions of the subjects it regulates. A prime example of a general description in hard law is found in an EU directive, specifically a 12-page definition regarding components allowed in fruit preserves, jams, and similar spreads for use on bread.
- Not all hard laws contain such specific definitions. For example, the European Convention on Human Rights leaves several terms open to interpretation, such as the section on the elements of "inhuman treatment and degrading dignity." This flexibility allows national leaders to apply the text in unforeseen situations when drafting the agreement.
- Providing a narrowed definition of a term reduces the possibility of a member state using it to justify self-serving behavior in the future and eliminates ambiguous interpretations. However, countries can still create a soft law text that allows for various interpretations, provided they agree on a dominant perspective.
Understand the Explanation and Enforcement

- Independent bodies that provide legal interpretations and settle disputes are common in international organizations. Their decisions are binding on the member states. For example, the International Tribunal for the Law of the Sea resolves disputes between member states based on the 1982 United Nations Convention on the Law of the Sea.
- Typically, rulings from international courts are only binding on the parties involved in a specific dispute.

- Under the United Nations Charter, if approved by the Security Council, nations can enforce international agreements through military means. This is the most stringent enforcement mechanism under international law.
- Pragmatist legal scholars often point out the lack of enforcement mechanisms in international law as evidence that all international legal texts inherently possess soft law characteristics.

- International governing bodies, such as the European Union, hold supreme enforcement power. The EU also has specialized regulatory agencies.
- Hard law often establishes independent bodies to interpret and enforce the law. For example, the European Court of Human Rights interprets and enforces the European Convention on Human Rights.
