International human-rights law (UDHR + covenants)

The International Bill of Rights

International human-rights law (IHRL) rests on a three-instrument architecture collectively called the International Bill of Rights. First came the Universal Declaration of Human Rights (UDHR), adopted by UN General Assembly Resolution 217A (III) on 10 December 1948 with 48 states in favour, 8 abstentions (the Soviet bloc, Saudi Arabia, South Africa) and none against. The UDHR is a General Assembly resolution, not a treaty; it was not binding when adopted. Its 30 articles span civil-political rights (life, fair trial, expression) and economic-social-cultural rights (work, education, social security). Eleanor Roosevelt chaired the drafting commission and the principal drafter was René Cassin.

Because a declaration cannot bind, the Commission on Human Rights split the project into two binding covenants, opened for signature on 16 December 1966 and entering into force in 1976:

• The International Covenant on Civil and Political Rights (ICCPR), in force 23 March 1976, with its Human Rights Committee (Article 28) and a First Optional Protocol allowing individual communications and a Second Optional Protocol (1989) abolishing the death penalty.
• The International Covenant on Economic, Social and Cultural Rights (ICESCR), in force 3 January 1976, requiring "progressive realization" to "the maximum of available resources" (Article 2(1)), monitored by the Committee on Economic, Social and Cultural Rights (created by ECOSOC Resolution 1985/17).

Universal but customary in part

The Cold War divide drove the bifurcation: Western states prioritized justiciable civil-political rights; the Soviet bloc and post-colonial states stressed socio-economic rights and self-determination, the shared Article 1 of both Covenants. Over time, parts of the UDHR hardened into customary international law — the prohibitions of torture, slavery, racial discrimination and arbitrary detention are widely treated as binding on all states regardless of treaty ratification, and torture, genocide and slavery are recognized as jus cogens (peremptory norms under Article 53 of the 1969 Vienna Convention).

The Vienna Declaration and Programme of Action (1993) proclaimed all human rights "universal, indivisible, interdependent and interrelated," rejecting any hierarchy between the two Covenants. It also created the Office of the UN High Commissioner for Human Rights (UNGA Resolution 48/141, 1993).

The treaty system later expanded into nine core instruments, including CERD (1965), CEDAW (1979), CAT (1984), CRC (1989), and the CRPD (2006), each with a monitoring committee. Candidates must distinguish the treaty-based bodies (committees of independent experts) from the Charter-based bodies — chiefly the Human Rights Council, created by UNGA Resolution 60/251 (2006) to replace the discredited Commission on Human Rights, and its Universal Periodic Review mechanism under which every UN member state is reviewed roughly every 4.5 years.

Derogations, reservations and limits

IHRL is not absolute. ICCPR Article 4 permits derogation "in time of public emergency which threatens the life of the nation," provided the state officially proclaims the emergency and notifies other parties through the UN Secretary-General. But Article 4(2) lists non-derogable rights that survive any emergency: the right to life (Art. 6), the prohibition of torture (Art. 7), of slavery (Art. 8), of imprisonment for debt (Art. 11), freedom from retroactive criminal law (Art. 15), recognition as a person before the law (Art. 16), and freedom of thought, conscience and religion (Art. 18). Memorize this list — it is a recurring objective-question target.

Many rights are also subject to ordinary limitation clauses allowing restrictions "prescribed by law" and "necessary" for public order, health, morals or the rights of others (e.g., Articles 18, 19, 21, 22). The Human Rights Committee's General Comment No. 34 (2011) tightened the necessity-and-proportionality test for free-expression restrictions.

Reservations are governed by the Vienna Convention's object-and-purpose test (Article 19); the Committee's General Comment No. 24 (1994) controversially asserted that reservations incompatible with the Covenant are severable and the state remains bound — a position several states rejected.

Why this matters for the exam

IHRL feeds UPSC GS-2 (international institutions, bodies and their mandates; India's stance on human-rights treaties), the FSOT job-knowledge and the multilateral-affairs cone, CSS International Law and Current Affairs, and BCS international-affairs sections. Examiners test it in three predictable ways.

First, factual recall: dates (1948, 1966, 1976), drafters (Cassin, Roosevelt), the resolution numbers (217A, 60/251), which body monitors which treaty, and the non-derogable rights list. Prelims and MCQ papers reward this precision.

Second, conceptual contrasts: declaration versus covenant (binding force), treaty-based versus Charter-based bodies, immediate civil-political obligations versus the "progressive realization" standard of ICESCR, and the universality-versus-cultural-relativism debate sharpened at the 1993 Vienna Conference.

Third, critical evaluation in essays: the enforcement deficit. The Human Rights Committee issues non-binding "Views"; the Human Rights Council can suspend members (Libya, 2011; Russia, April 2022 via UNGA Resolution ES-11/3) but lacks coercive power. A high-scoring answer pairs the normative achievement with the implementation gap, citing UPR, special rapporteurs and the limits of state consent.

India PYQ angle: India ratified both Covenants in 1979 but has not ratified CAT (1984) or its Optional Protocols, and entered reservations on ICCPR Article 1 (self-determination). Know this for GS-2 questions on India and international human-rights regimes.
