Part 5 · Human rights under international law
This is where international law reaches the individual. The exam tests it as a problem with a fixed rhythm: can this person get a complaint to the Human Rights Committee, would it succeed on the merits, and what would the Committee's Views actually change? Admissibility first, merits second, effect last.

From Declaration to Covenants
The Charter itself opens the door: art 1 makes promoting and encouraging respect for human rights and fundamental freedoms a purpose of the United Nations. The Universal Declaration of Human Rights walked through it in 1948. Proclaimed by the General Assembly as "a common standard of achievement for all peoples and all nations", it spans both limitations on power, such as the prohibitions on torture and slavery, and rights conferred by government, such as social security, employment, health and education. It is the foundation, but it is a General Assembly proclamation, not a treaty.
The treaty form arrived in 1966. The Declaration became the basis for two Covenants: the International Covenant on Civil and Political Rights and the International Covenant on Economic, Social and Cultural Rights. Together with the Declaration and the ICCPR's two Optional Protocols they make up what is called the International Bill of Human Rights. The general design of human rights treaties has two elements: they set out substantive rights, and they establish independent monitoring committees to oversee implementation. Both elements are examinable, and the second is where most problems live.
The obligations and their limits
Article 2 of the ICCPR carries the load. Each state party undertakes to respect and to ensure to all individuals within its territory and subject to its jurisdiction the rights recognised in the Covenant, without distinction of any kind (art 2(1)). Where existing measures are inadequate, the state must adopt laws or other measures to give effect to the rights (art 2(2)). And the state must ensure that any person whose rights are violated has an effective remedy, determined by competent authorities and enforced when granted (art 2(3)). The rights themselves sit in Part III, arts 6 to 27: life, freedom from torture and slavery, liberty and security, humane treatment in detention, movement, fair trial, privacy, conscience and religion, expression, assembly, association, family, children, voting, equality before the law, and the rights of minorities to enjoy their own culture.
Few of those rights are absolute, and the Covenant limits them in three distinct ways. Some rights carry express limitation clauses: freedom of religion may be limited only as necessary to protect public safety, order, health or morals or the fundamental rights and freedoms of others (art 18(3)), which invites a proportionality analysis of the objective, the means and the balance of good against harm. Some rights prohibit only what is arbitrary, such as arbitrary arrest or detention (art 9(1)), which builds a reasonableness inquiry into the right itself. And some rights require balancing against others, as freedom of expression under art 19 meets the prohibition on incitement to hatred under art 20(2).
The Human Rights Committee
The ICCPR's monitoring body is the Human Rights Committee, established by art 28 and comprised of 18 members serving in their personal capacity. Do not confuse it with the Human Rights Council, a separate body under the General Assembly. The Committee works through four mechanisms. States must submit periodic reports on the measures giving effect to their obligations (art 40), which the Committee answers with concluding observations. It issues General Comments interpreting specific rights. It can receive state-to-state complaints where states have accepted that competence (art 41), a mechanism never utilised. And, for the 116 states that have ratified the First Optional Protocol, it receives individual communications, which is the mechanism the exam cares about.
The individual communication
Admissibility comes first, and it is a gate with five bars drawn from the First Optional Protocol. The author must be a victim of a violation of a Covenant right (art 1), which requires more than a theoretical possibility of harm: the impairment must have occurred or be imminent (Billy v Australia). The communication must be in writing (art 2). It cannot be anonymous (art 3). The same matter must not be under examination by another international procedure (art 5(2)(a)). And the author must have exhausted all available domestic remedies, unless their pursuit is unreasonably prolonged (art 5(2)(b)).
Only then come the merits. The Committee considers the communications of the author and the state party and determines the claim against the rights in Part III. If it finds a violation, it issues Views with recommendations. The Views are not binding orders and the Committee has no coercive enforcement power. But they are not nothing: under art 2(3) the state is obliged to ensure an effective remedy for a violation, pacta sunt servanda compels performance of the Covenant in good faith (VCLT, art 26), and the Committee may seek information on implementation and place a non-complying state under a follow-up procedure.
Billy v Australia, worked through
The prescribed illustration is Billy v Australia (2022), a communication by eight Indigenous Australians from low-lying Torres Strait Islands who alleged that Australia's failure to implement adequate climate adaptation measures, and its failure to mitigate emissions, violated the Covenant. On admissibility, the Committee held the matter was not before another international procedure, domestic remedies were exhausted, the claim was not precluded by overlap with other conventions, and the authors faced more than a theoretical possibility of harm: the impairment of their rights was already occurring and ongoing. Note one refinement: the claim under art 2 alone was inadmissible, because art 2 states a general obligation and grounds a communication only through a distinct violation of a substantive right.
On the merits the same facts split three ways. The art 17 claim succeeded: failure to implement adequate adaptation measures to protect the authors' home, private life and family breached Australia's positive obligations. The art 27 claim succeeded: delayed and inadequate adaptation failed to protect the ability of a minority culture to maintain its traditional way of life and transmit it to future generations. The art 6 claim failed: there was no real and reasonably foreseeable risk of physical endangerment or extreme precarity threatening the right to life. The remedy followed art 2(3): adequate compensation, meaningful consultation with the communities, continued implementation of measures for their safe existence, and monitoring and review.
The answer that earns the marks
Attack plan. Five steps, in this order. 1. Consent: is the respondent a party to the ICCPR and the First Optional Protocol? 2. Admissibility: run the five-bar gate, with a sentence per bar. 3. Merits: identify each Part III right engaged, state its threshold, and apply, using Billy as your model of rights splitting on the same facts. 4. Remedy: what would the Committee request under art 2(3)? 5. Effect: Views are not binding, but art 2(3) and VCLT art 26 oblige a good faith response.
Worked example
Nadia is detained by a state party to the ICCPR and the First Optional Protocol. Guards leak her private medical information and she is then held in a windowless isolation cell for 20 hours a day after complaining. Her challenges under domestic law have failed and no appeal remains. Advise on a complaint to the Human Rights Committee. Do not address the merits in detail.
A Pass answer says. Nadia can complain to the Human Rights Committee because the state has ratified the ICCPR and the Optional Protocol. She must put the complaint in writing and cannot be anonymous, and she has exhausted domestic remedies because her challenges failed. Her treatment seems to breach her rights, so the Committee would probably find for her and order the state to release her. This covers some admissibility bars but misses the victim requirement and the parallel procedure bar, and the word "order" gives away a misunderstanding of what Views are.
An H1 answer says. The route exists because the state is party to both the Covenant and the First Optional Protocol. Admissibility then turns on five requirements. Nadia is a victim of alleged violations that have already occurred, not a theoretical possibility of harm (art 1; Billy v Australia). The communication must be in writing (art 2) and cannot be anonymous (art 3), which matters here because her complaint necessarily discloses the private information she says was leaked, and she should be advised of that cost. The same matter must not be before another international procedure (art 5(2)(a)), so she must choose her forum. Domestic remedies are exhausted, since her challenges failed and no appeal remains (art 5(2)(b)). The communication is therefore admissible. If the Committee later issued Views in her favour, it would request an effective remedy under art 2(3); the Views would not bind as a judgment, but pacta sunt servanda (VCLT, art 26) obliges the state to respond in good faith.
Critical pitfalls and counter-arguments
- Skipping admissibility. The merits of an inadmissible communication are worth nothing. Five bars, in order, every time.
- Confusing the Committee with the Council. The Human Rights Committee is the ICCPR treaty body of 18 experts; the Human Rights Council is a separate body under the General Assembly.
- Running art 2 as a standalone claim. Billy holds that art 2 states general obligations and grounds a communication only through a distinct violation of a substantive right.
- Blurring limitation and derogation. Art 18(3) is the permanent, proportionate limit; art 4 is emergency suspension, and it never reaches arts 6, 7, 8(1) and (2), 11, 15, 16 or 18.
- Overclaiming or dismissing Views. They are not enforceable judgments, and they are not mere suggestions: art 2(3) and VCLT art 26 make non-compliance a breach of good faith performance, with reputational and follow-up consequences.
Take it to the practice bank
Every mechanism in this guide is drilled in the Principles of Public Law practice bank, in the Human Rights under International Law set of ten problems. Problem 1 tests derogation in a public emergency and Problem 2 the non-derogable core; Problem 3 works the limitation clauses and proportionality; Problem 5 tests reservations against the object and purpose test; Problem 6 contrasts the ICCPR's immediate duties with ICESCR progressive realisation; Problem 8 examines the status of the UDHR; and Problem 9 asks exactly what separates treaty body Views from binding judgments. Each comes with a realistic Pass answer, an H1 model answer and the examiner's comments.
Practice prompts
- Write the five-bar admissibility paragraph from memory with an article number attached to every bar, then check it against the First Optional Protocol.
- Take the Billy facts and write the art 6 paragraph twice: once as the Committee decided it, once as a persuasive argument the other way. Keep the threshold language exact in both.
- Draft the two-mark answer to "what would be the legal effect of Views in the applicant's favour?" in under 120 words, citing art 2(3) and VCLT art 26 and never using the word "order".
