MILITARY NECESSITY [7 records]

Record 1 2024-03-27

English

Subject field(s)
  • War and Peace (International Law)
  • Military Law
CONT

Jus in bello, also referred to as international humanitarian law (IHL), applies to all warring parties irrespective of the reasons for the conflict. It does not speak to whether or not the cause of war is just. Instead, this body of law seeks to protect war victims and their fundamental rights, no matter to which party they belong.

CONT

Necessity and proportionality have always been core principles of both branches of the jus belli principles that apply to both the authority to employ military force and the regulation of actual employment. However, in the jus ad bellum context, they have never before been viewed as principles to regulate operational and tactical execution. Instead, in that context they frame the legality of national or multinational resort to military force in self-defense. Once the decision is made to employ force pursuant to this authority, the jus in bello variant of these principles(necessity of the mission and proportionality of collateral damage) operate to regulate the application of combat power during mission execution(in other words, they provide the foundation for the regulation of the application of combat power in the context of the self-defense-justified mission).

French

Domaine(s)
  • Guerre et paix (Droit international)
  • Droit militaire
CONT

Le droit international humanitaire a pour but de limiter les souffrances causées par la guerre en assurant, autant que possible, protection et assistance aux victimes. Il traite donc de la réalité d'un conflit sans considération des motifs ou de la légalité d'un recours à la force. Il en réglemente uniquement les aspects ayant une importance humanitaire. C'est ce que l’on appelle le jus in bello (le droit dans la guerre).

Record 6 1999-11-24

English

Subject field(s)
  • International Public Law
CONT

Classifications of "defences" or "justifications" are conventional and not very logical.... Necessity as an omnibus category probably does not exist, and its availability as a defence depends on specialized rules. In particular contexts in the law of war, military necessity may be pleaded, and the right of angary allows requisition of ships belonging to aliens lying within the jurisdiction in time of war or other public danger.

OBS

However, attractive as such a doctrine might be in municipal law, in international relations it would encourage too many breaches of the peace if widely adopted.

French

Domaine(s)
  • Droit international public
DEF

Cas d'exonération de responsabilité internationale appliquée en faveur d'un État dès lors que celui-ci est en mesure de démontrer que l'atteinte, qu'il a portée à une de ses obligations internationales a été justifiée par une nécessité absolue.
