Issues International Law & Security International Law & Security Fact Sheet



1. What is international law?
International law consists of rules and principles, which govern the relations and dealings of nations with each other. It can only work if the nation-states, which make up the system, accept and abide by those rules.

2. Where do these rules come from?
They come from several places. First, sometimes states consistently follow certain general practices out of a sense of legal obligation (customary law). Second, the rules may come from international agreements (conventional law). And third, general principles that are common to the national laws of many states usually contribute to international law.

3. What is the role of international law?
International law provides an alternative to the use of force in settling disputes by relying on compromise, cooperation, mutual legal obligations, and common ends. In today’s world of increasingly interdependent nations and economies, the resolution of conflicts without violence is more essential than ever.

4. Is international law enforceable?
Yes, there are several mechanisms by which international law can be enforced. One way is through the use of international pressure short of the use of force, such as economic pressure. Another is prompted by a nation’s wish to maintain a favorable public (national as well as international) image. This is particularly integral to the enforcement of human rights law. Also, nations must realize that in order for international law to function, each nation-state must assume responsibility for its enforcement. One of the ways in which they can do this is by supporting and participating in international bodies, such as the United Nations.

5. What is the United Nations?
The United Nations is an international organization (one created by international agreement and/or has membership consisting primarily of nations) that was formed in 1954. Today it has 191 Member States. Its declared purposes are to maintain peace and security, to develop friendly relations among nations, to achieve international cooperation in solving international problems, and to be a center for harmonizing the actions of the nations and attaining their common ends. The UN Charter specifically calls on it to undertake the progressive codification and development of international law.

6. What does the UN Charter say about the use of force/crimes of aggression?
The UN Charter prohibits Member States from using force or threatening to do so in their international relations with other states (Chapter I, Article 2, Section 4). If a threat or breach of the peace occurs, the Security Council is to decide what shall be done to restore international peace and security (Chapter VII, Article 39).

7. What are some UN bodies that help determine international law?
The UN has numerous committees and sub-committees that govern different facets of international law. The main committee is the Sixth Committee of the General Assembly, which deals with matters of international law. There is also the International Law Commission that prepares drafts on topics of international law, which can then be incorporated into conventions and opened for signature and ratification by States. The Commission on International Trade Law and the Commission on Human Rights are two other examples.

8. What is humanitarian law?
Humanitarian law is an international body of rules, which, in wartime, protects persons who are not or are no longer participating in the hostilities and restricts the means and methods of warfare. Its central purpose is to limit and prevent human suffering in times of armed conflict.

9. How has humanitarian law been established?
International humanitarian law developed in the 19th and 20th centuries. It was codified in the four Geneva Conventions of 1949 and their two Additional Protocols of 1977, which are the principle instruments of humanitarian law. Two of the basic rules that they established are:
1) It is prohibited to employ weapons or methods of warfare of a nature to cause unnecessary losses or excessive suffering (e.g. chemical and/or biological weapons).
2) Parties to a conflict shall at all times distinguish between the civilian population and combatants in order to spare the civilian population and their property. Attacks shall be directed solely against military objectives.

10. What is human rights law?
While humanitarian law applies in situations of armed conflict, international human rights law, being tailored primarily for peacetime, applies at all times. Its principal goal is to protect individuals from unjust and/or cruel behavior by their own governments.

11. What are some implementing mechanisms for human rights law?
The primary document behind international human rights law is the Universal Declaration of Human Rights, which was adopted by the UN General Assembly in 1948. As a General Assembly resolution, it is considered “soft law.” Supplementing the Universal Declaration are two treaties: the International Covenant on Civil and Political Rights, which entered into force in1966 and the International Covenant on Social, Economic, and Cultural Rights, which into force in 1966.

12. What are the main principles/guarantees of human rights law?
International human rights law states that the right to life, the prohibition of torture and inhuman punishment or treatment, slavery and servitude, and the principle of legality and non-retroactivity of the law must be respected in all circumstances. It also stipulates that states must guarantee rights to self-determination, property, due process, fair working conditions, access to health care, and education.

13. What is the International Criminal Court (ICC)?
The ICC was established by the Rome Statute in 1998 and officially came into force on July 1, 2002. It is the first ever permanent, treaty-based, international judicial body capable of investigating and trying individuals accused of the most serious violations of international humanitarian and human rights law, namely genocide, crimes against humanity and war crimes. Like preceding ad hoc international criminal tribunals, the ICC is based on the idea that individuals can and should be held criminally accountable for the actions of states.

14. What, more specifically, is the ICC’s purpose?
The ICC makes international standards of conduct more specific, provides an important mechanism for implementation of these standards and ensures that the perpetrators are brought to justice before the ICC when national Courts are unable or unwilling to do so. Equally important could be the impact on national laws as ratifying nations fulfill their obligation to ensure that these crimes can be tried within their own borders.

15. What is the U.S. stance regarding the ICC?
President Bill Clinton signed the 1998 Rome Statute in December 2000. Less than six months after that, however, the Bush administration withdrew the US signature on the treaty and announced that it has no intention to become party to the Statute. Furthermore, the U.S. has repeatedly tried to undermine the Court and this opposition is creating tensions with allied nations, nearly all of which have signed and ratified the treaty and with the international community at large.

16. Are nuclear weapons illegal under international law?
In July of 1996 the International Court of Justice (ICJ), the principal judicial organ of the United Nations, gave an Advisory Opinion about the Legality of the threat or use of nuclear weapons. The 14 judges concluded unanimously that the use of nuclear weapons would generally be contrary to the principles and rules of international humanitarian law. The ICJ further noted that even “in an extreme circumstance of self-defense,” humanitarian law applies. The ICJ also did not accept the argument that the use of small, precisely targeted tactical nuclear weapons would conform to international law. Although today there is no comprehensive and universal prohibition against nuclear weapons, the ICJ stated that the nuclear weapons states are obligated to negotiate a treaty leading to nuclear disarmament.
