Safeguarding Human Rights: Constitutional Protection and International Standards

When a country signs a human rights treaty, what actually changes for an ordinary citizen? A signature on an international document does not, by itself, give anyone an enforceable right at home. The real story of human rights protection lies in how those international promises travel from the global stage into national constitutions, courts, and statute books. This is the heart of the relationship between international human rights standards and constitutional protection, where treaties either become living law that people can claim or remain distant ideals.

From declarations to binding obligations 🔗

The modern human rights system began as a moral statement and slowly hardened into law. The Universal Declaration of Human Rights, adopted in 1948, set out fundamental freedoms but could not legally compel governments to act. To give these ideals legal force, the United Nations General Assembly adopted two binding treaties on 16 December 1966: the International Covenant on Civil and Political Rights (ICCPR) and the International Covenant on Economic, Social and Cultural Rights (ICESCR). Both entered into force in 1976 once enough states had ratified them, and together with the Universal Declaration they form what is known as the International Bill of Human Rights.

The two covenants divide the field of rights. The ICCPR covers the right to life, freedom of speech, religion, and political participation, while the ICESCR addresses food, education, health, and an adequate standard of living. There is an important difference in how states must deliver them. The ICCPR creates obligations that are largely immediate, whereas the ICESCR asks states to take steps to the maximum of available resources to progressively realise its rights. This distinction shapes how courts and governments treat each set of rights even today.

Monism and dualism: two doors into domestic law 🔗

Ratifying a treaty is a promise made between states. Whether that promise becomes enforceable inside a country depends on the legal tradition that the country follows. Broadly, two approaches exist.

The monist approach 🔗

In a monist system, international law and domestic law form a single legal order. Once a treaty is ratified, it automatically becomes part of the law of the land, and citizens can invoke it directly before national courts without any separate legislation. Several European countries follow this path, which is why ratified treaties can have immediate domestic effect there.

The dualist approach 🔗

In a dualist system, international law and domestic law are two distinct spheres. A ratified treaty creates obligations on the state at the international level, but it does not become enforceable at home until the national legislature passes a law incorporating it. India follows this dualist tradition, which means even a ratified covenant does not automatically give an individual a right enforceable in court until Parliament acts. Understanding this difference explains why the same treaty can protect a citizen strongly in one country and only weakly in another.

The European model: treaties as enforceable domestic law 🔗

The most developed example of regional human rights protection sits in Europe. The European Convention on Human Rights (ECHR), dating from 1950 under the Council of Europe, has been incorporated into the domestic law of many member states. This means individuals can rely on Convention rights directly in their national courts, not just in distant international forums.

What makes the European system distinctive is its enforcement machinery. The European Court of Human Rights in Strasbourg accepts individual complaints against any state that has ratified the Convention, but only after the complainant has exhausted domestic remedies. Over the decades it has produced a vast body of jurisprudence that genuinely shapes how governments behave. Because the ECHR enjoys the status of enforceable law domestically and is backed by a court whose judgments are binding, it stands as the benchmark against which other systems are measured.

The Americas and Africa: developing systems 🔗

Two other major regional systems exist, each at a different stage of development. The Inter-American system was established by the American Convention on Human Rights in 1969 within the Organization of American States. It works through the Inter-American Commission on Human Rights and the Inter-American Court of Human Rights. Unlike the European system, ratification of the American Convention is not required of all member states, so its reach is more uneven across the region.

The youngest of the three is the African system, built on the African Charter on Human and Peoples’ Rights of 1981, also called the Banjul Charter. It is enforced through the African Commission on Human and Peoples’ Rights and the more recently created African Court on Human and Peoples’ Rights. A notable feature is that under Articles 60 and 61, the African Commission is mandated to look beyond the Charter itself and draw on wider international standards when assessing complaints.

Encouragingly, these courts increasingly talk to one another. In 2018 the three regional courts adopted the San José Declaration and set up a Permanent Forum of Institutional Dialogue, sharing case law and meeting regularly. This judicial dialogue helps build a more consistent global understanding of what human rights require.

How the Constitution protects international standards 🔗

India is a signatory to the Universal Declaration of Human Rights and has ratified both the ICCPR and the ICESCR. Yet because of the dualist tradition, the deeper protection of these international standards comes from the Constitution itself rather than from automatic treaty incorporation.

Fundamental Rights as the core guarantee 🔗

The most powerful protection lies in Part III of the Constitution, which guarantees Fundamental Rights from Article 14 to Article 32. These include the right to equality (Articles 14 to 18), the freedom of speech and expression (Article 19), and the right to life and personal liberty (Article 21). Crucially, these rights are enforceable: a citizen can move the Supreme Court directly under Article 32 and the High Courts under Article 226 when these rights are violated. The drafters of Part III were clearly influenced by the Universal Declaration, so many international civil and political rights already live within the constitutional text as enforceable guarantees.

Directive Principles and constitutional commitment to international law 🔗

Economic and social rights of the kind found in the ICESCR appear largely in the Directive Principles of State Policy (Articles 36 to 51). These are not directly enforceable in court but are fundamental to governance and guide state policy. Within this Part sits a key provision: Article 51(c), which directs the state to foster respect for international law and treaty obligations. Alongside it, Article 253 empowers Parliament to make any law to implement international treaties and conventions, even on subjects that would otherwise fall outside its legislative competence. Together, these articles form the constitutional bridge between international standards and domestic law.

Statutory protection 🔗

Parliament has also given effect to international commitments through legislation. The Protection of Human Rights Act, 1993 established the National Human Rights Commission, which defines human rights to include rights guaranteed by the Constitution as well as those embodied in the International Covenants and enforceable by courts in India. This statutory definition deliberately links domestic enforcement to international standards.

The judiciary as the great connector 🔗

The most striking development is how the courts have used the Constitution to read international human rights standards into domestic law, softening the strict dualist position. The landmark example is Vishaka v. State of Rajasthan (1997), where the Supreme Court faced a complete absence of any law on sexual harassment at the workplace. Drawing on the equality and dignity guarantees in Articles 14, 15, 19(1)(g), and 21, the Court held that any international convention consistent with fundamental rights and in harmony with their spirit must be read into these provisions to enlarge their meaning. It grounded this reasoning in Article 51(c) and the power of Parliament under Article 253, and it framed binding guidelines until legislation was passed.

The courts have, however, kept a clear limit. As reaffirmed in People’s Union for Civil Liberties v. Union of India, an international treaty cannot be enforced by courts unless it has been enacted into domestic law, although judges may refer to international instruments to interpret domestic provisions, especially when there is ambiguity or a legislative gap. This combination of constitutional guarantees and a willing judiciary is what gives international human rights standards real protection within the country.

Where the protection still falls short 🔗

Constitutional protection is strong but not seamless. Ratified treaties remain unenforceable on their own until Parliament legislates, which can leave gaps where political will is lacking. Economic and social rights, sitting mainly in the non-justiciable Directive Principles, depend heavily on creative judicial interpretation through Article 21 to gain teeth. And unlike Europe, where citizens can take their government to a regional court, individuals in Asia have no comparable regional human rights court to turn to once domestic options run out. The protection is therefore real, but it relies more on constitutional interpretation and judicial activism than on direct treaty enforcement.

What do you think? Should a country like India move closer to the monist model so that ratified human rights treaties become automatically enforceable, or does the dualist approach rightly protect democratic and parliamentary control over which international standards become binding law?
