Frequently Asked Questions
61. What is International Humanitarian Law (IHL) and what are its core principles?
International Humanitarian Law (IHL), also known as the Law of Armed Conflict, is a set of rules that seeks to limit the effects of armed conflict. Its core principles are humanity, impartiality, neutrality, and independence. IHL protects people who are not participating in hostilities, such as civilians, medical personnel, and prisoners of war. It also restricts the means and methods of warfare to minimize suffering and maintain some level of humanity during war.
Exam Tip
Remember the core principles (humanity, impartiality, neutrality, independence) using the acronym HINI.
2. What are the key provisions of International Humanitarian Law (IHL) regarding the protection of civilians during armed conflict?
IHL provides several key protections for civilians during armed conflict:
- •IHL applies only during armed conflict, whether international (between states) or non-international (within a state).
- •Civilians are protected from direct attack unless they directly participate in hostilities.
- •Attacks must be directed only at military objectives.
- •Indiscriminate attacks that do not distinguish between military and civilian targets are prohibited.
- •The principle of proportionality requires that attacks must not cause civilian harm that is excessive in relation to the concrete and direct military advantage anticipated.
Exam Tip
Focus on the distinction between combatants and civilians, and the principle of proportionality.
3. How has International Humanitarian Law (IHL) evolved over time, and what were some of the key milestones in its development?
The roots of IHL can be traced back centuries, with early customs and treaties attempting to regulate warfare. The modern IHL system largely developed in the mid-19th century. Key milestones include:
- •The Lieber Code, issued in 1863 during the American Civil War, was one of the first attempts to codify the laws of war.
- •The Geneva Conventions, first adopted in 1864, focused on the protection of wounded soldiers.
- •The Hague Conventions of 1899 and 1907 expanded the scope of IHL.
Exam Tip
Remember the Lieber Code, Geneva Conventions, and Hague Conventions as key historical developments.
4. What are the challenges in the implementation of International Humanitarian Law (IHL) in contemporary armed conflicts?
Several challenges exist in implementing IHL in contemporary armed conflicts:
- •The increasing focus on the protection of civilians in urban warfare, given the high risk of civilian casualties.
- •The use of autonomous weapons systems (AWS) is raising concerns about compliance with IHL principles.
- •Strengthening accountability for violations of IHL, including through national and international courts.
Exam Tip
Consider the impact of new technologies and the changing nature of warfare on IHL implementation.
5. How does International Humanitarian Law (IHL) apply in non-international armed conflicts (NIACs)?
IHL applies to both international armed conflicts (between states) and non-international armed conflicts (within a state). While the rules governing NIACs are less detailed than those for international conflicts, Common Article 3 of the Geneva Conventions provides a fundamental level of protection. It prohibits violence to life and person, in particular murder of all kinds, mutilation, cruel treatment and torture; taking of hostages; outrages upon personal dignity, in particular humiliating and degrading treatment; the passing of sentences and the carrying out of executions without previous judgment pronounced by a regularly constituted court, affording all the judicial guarantees which are recognized as indispensable by civilized peoples.
Exam Tip
Understand the significance of Common Article 3 of the Geneva Conventions for NIACs.
6. What is the significance of the principle of proportionality in International Humanitarian Law (IHL)?
The principle of proportionality in IHL requires that attacks must not cause civilian harm that is excessive in relation to the concrete and direct military advantage anticipated. This means that even if an attack is directed at a legitimate military objective, it is still unlawful if the expected civilian casualties or damage to civilian objects are disproportionate to the military gain.
Exam Tip
Proportionality doesn't mean no civilian casualties, but that the harm must be balanced against the military advantage.
