General protection of civilian objects
[p.629] Article 52
-- General protection of civilian objects
[p.630] 1994 This article is of considerable importance. In fact, in order to apply the basic rule contained in Article 48
' (Basic rule), ' it is necessary to know what constitutes civilian objects, on the one hand, and military objectives, on the other. For a long time attempts have been made to define military objectives.
1995 For example, Hague Convention IX of 1907 Concerning Bombardment by Naval Forces in Time of War (1) contains the following provisions:
-- The bombardment by naval forces of undefended ports, towns, villages, dwellings, or buildings is forbidden [...] Article 2
-- Military works, military or naval establishments, depots of arms or war ' matériel, ' workshops or plants which could be utilized for the needs of the hostile fleet or army, and the ships of war in the harbour, are not, however, included in this prohibition [...]"
1996 These rules are accompanied by provisions relating to the warning which must be given before attacks; they have rarely been applied,
but they give some idea of what was meant by military objectives at
1997 The Commission of Jurists which met in The Hague in 1922 with the task of examining a partial revision of the laws of war, drew up a
draft (2),Article 24 of which is devoted to the definition of
civilian objects and military objectives:
1. An air bombardment is legitimate only when directed against a military objective, i.e. an objective whereof the total or
partial destruction would constitute an obvious military
advantage for the belligerent;
2. Such bombardment is legitimate only when directed exclusively against the following objectives: military forces, military
works, military establishments or depots, manufacturing plants
constituting important and well-known centers for the production
of arms, ammunition or characterized military supplies, lines of
communication or transport which are used for military purposes;
3. Any bombardment of cities, towns, villages, habitations and buildings which are not situated in the immediate vicinity of the
operations of land forces is forbidden [...];
4. In the immediate vicinity of the operations of the land forces, the bombardment of cities, towns, villages, habitations and
buildings is legitimate, provided there is a reasonable
presumption that the military concentration is important enough
to justify the bombardment, taking into account the danger to
which the civil population will thus be exposed [...]"
1998 This attempt to define civilian objects and military objectives was not followed by a codification and the two Geneva Conventions of
1929 relating to the wounded and sick and to prisoners of war did not
contain any provisions on this matter, even though they were based on
the existence of a distinction between combatants and military
objectives, on the one hand, and civilians and civilian objects, on
1999 The same was true in 1949 in Geneva during the drafting of the four 1949 Conventions. Nevertheless, military objectives are
repeatedly referred to explicitly in the 1949 Conventions. For
example, Article 19
of the First Convention requires that the
responsible authorities ensure that medical establishments and units
are, as far as possible, situated in such a manner that attacks
against military objectives cannot imperil their safety. Article 18
of the Fourth Convention contains a similar provision for the benefit
of civilian hospitals.
2000 Although States in general recognized that attacks should only be directed against military objectives, there was no agreed definition
of such objectives, and in fact, during the Second World War and
during several armed conflicts which have taken place since then,
each belligerent determined what should be understood by such
objectives as it pleased. It should be noted that their ideas often
differed considerably, depending on whether the territory concerned
was their own, enemy territory, or territory of an ally occupied by
enemy forces. Thus a restrictive definition was necessary if the
essential distinction between combatants and civilians and between
civilian objects and military objectives was to be maintained.
2001 A partial definition was offered incidentally by the Hague Convention of 1954 for the Protection of Cultural property. Article
, paragraph 1, of that Convention reads as follows:
"1. There may be placed under special protection a limited number of refuges intended to shelter movable cultural
property in the event of [p.632] armed conflict, of
centres containing monuments and other immovable cultural
property of very great importance, provided that they:
a) are situated at an adequate distance from any large industrial centre or from any important military
objective constituting a vulnerable point, such as,
for example, an aerodrome, broadcasting station,
establishment engaged upon work of national defence,
a port or railway station of relative importance or a
main line of communication;
b) are not used for military purposes."
2002 In 1956 the ICRC submitted its Draft Rules for the Limitation of Dangers incurred by the Civilian Population in Time of War, Article 7
of which provided that:
n order to limit the dangers incurred by the civilian population, attacks may only be directed against military
Only objectives belonging to the categories of objective which, in view of their essential characteristics, are
generally acknowledged to be of military importance, may be
considered as military objectives. Those categories are
listed in an annex to the present rules.
However, even if they belong to one of those categories, they cannot be considered as a military objective where their total or partial destruction, in the circumstances ruling at the time, offers no military advantage." (3)
[p.633] 2003 The Institute of International Law, which met in Edinburgh in 1969 in order to study weapons of mass destruction, included in its
definition of military objectives
"only those which by their very nature or purpose or use, make an effective contribution to military action, or exhibit
a generally recognized military significance, such that their
total or partial destruction in the actual circumstances
gives a substantial, specific and immediate military
advantage to those who are in a position to destroy
2004 When the ICRC was called upon to draw up the Draft Protocol in 1970-1971, it faced a difficult problem. Should it define civilian
objects which may not be attacked, or, on the contrary, should it
define military objectives which may be attacked? Finally a
compromise was achieved. The ICRC draft reads as follows:
"' Article 47 -- General protection of civilian objects '
1. Attacks shall be strictly limited to military objectives, namely, to those objectives which are, by their
nature, purpose or use, recognized to be of military interest
and whose total or partial destruction, in the circumstances
ruling at the time, offers a distinct and substantial
2. Consequently, objects designed for civilian use, such as houses, dwellings, installations and means of transport,
and all objects which are not military objectives, shall not
be made the object of attack, except if they are used mainly
in support of the military effort."
2005 The Diplomatic Conference finally adopted a similar formula which combines the two possibilities; it begins by declaring civilian
objects immune and continues with an a contrario definition in
defining military objectives. (5)
2006 Before discussing the three paragraphs which this article comprises, it might be appropriate to devote some attention to the
2007 The English text uses the word "objects", which means "something placed before the eyes, or presented to the sight or other sense, an
individual thing seen, or perceived, or that may be seen or
perceived; a material thing". (6) The French [p.634] text uses the
word "biens", which means "chose tangible, susceptible
2008 It is clear that in both English and French the word means something that is visible and tangible.
2009 As regards the word "objective", in English this is an abbreviation of the expression "objective point", defined by the
Oxford Dictionary as follows: "the point towards which the advance of
troops is directed; hence, [...] the point aimed at". (8)
2010 In French the word "objectif" is defined as follows in the Dictionnaire Robert: "point contre lequel est dirigé une opération
stratégique ou tactique; par extension: résultat qu'on se propose
d'atteindre par une opération militaire". (9) There is however no
doubt that in this article both the English and French texts intended
tangible and visible things by the word "objective", and not the
general objective (in the sense of aim or purpose) of a military
operation; therefore the extended meaning given by the Dictionnaire
Robert is not included in this article.
2011 The first sentence lays down the general principle of immunity of civilian objects. Attacks are defined in Article 49
' (Definition of
attacks and scope of application). ' As regards the prohibition of
reprisals, reference may be made to what was said above with regard
to Article 51
' (Protection of the civilian population), ' paragraph
2012 The second sentence defines civilian objects by means of a negative method, which is already used in Article 50
' (Definition of
civilians and civilian population) ' to define the civilian
population. This method is justified by the fact that there are far
more civilian objects than military objectives.
2013 A vote was taken in Committee III on retaining the words "nor of reprisals", in this paragraph; the Committee decided to retain
them. (10) In explaining why it abstained from voting on this article
at the plenary meeting, one delegation indicated that it was opposed
to a prohibition of reprisals against civilian objects that would
apply in all circumstances; it considered that "the availability of
this sanction may persuade an adversary not to commit violations of
the law in the first place"; (11) but, as stated above, the
Conference did not share this point of view.
[p.635] Paragraph 2
2014 The first sentence confirms the principle laid down in paragraph 1.
2015 The second sentence raised a problem of a moral nature for many, particularly for the ICRC: should a humanitarian treaty describe
objects which may be attacked? After a great deal of thought it
seemed impossible to ensure effective protection for the civilian
population without indicating what objectives could legitimately be
attacked. Therefore in the draft the ICRC used the wording that is
found in this text, which includes a definition of military
objectives. This definition will prove useful for the population
itself, for it is in the latter's interests to know whether or not it
should avoid certain points that the adversary could legitimately
2016 The definition of military objectives had been the object of study for a long time, and the solution adopted by the Diplomatic
Conference is broadly based on earlier drafts. The text of this
paragraph certainly constitutes a valuable guide, but it will not
always be easy to interpret, particularly for those who have to
decide about an attack and on the means and methods to be used.
2017 It should be noted that the definition is limited to objects but it is clear that members of the armed forces are military objectives,
for, as the Preamble of the Declaration of St. Petersburg states:
"the only legitimate object which States should endeavour to accomplish during war is to weaken the military forces of the
enemy; [...] for this purpose it is sufficient to disable the
greatest possible number of men".
' (Armed forces) ' defines armed forces and provides that members of such forces are combatants, that is to say, they have the
right to participate directly in hostilities; the corollary is that
they may be the object of hostile acts.
2018 The definition comprises two elements:
a) the nature, location, purpose or use which makes an effective contribution to military action;
b) the total or partial destruction, capture or neutralization which in the circumstances ruling at the time offers a definite
Whenever these two elements are simultaneously present, there is a military objective in the sense of the Protocol.
2019 The ICRC proposal contained one element which was not retained: the objects should be recognized to be of military interest. On the
other hand, the definition adopted introduces an additional element:
the location. Similarly the concepts of "capture" and
"neutralization" were added. According to the Rapporteur, the
adjective "definite" was discussed at length. The adjectives
considered and rejected included the words: "distinct" (distinct),
"direct" (direct), "clear" (net), "immediate" (immédiat), "obvious"
(évident), "specific" (spécifique) and "substantial" (substantiel).
The Rapporteur of the Working Group added that he was not very clear
about the reasons for the choice of words that was made. (12)
[p.636] 2020 A closer look at the various criteria used reveals that the first refers to objects which, by their ' nature, ' make an effective
contribution to military action. This category comprises all objects
directly used by the armed forces: weapons, equipment, transports,
fortifications, depots, buildings occupied by armed forces, staff
headquarters, communications centres etc.
2021 The second criterion is concerned with the ' location ' of objects. Clearly, there are objects which by their nature have no
military function but which, by virtue of their location, make an
effective contribution to military action. This may be, for example,
a bridge or other construction, or it could also be, as mentioned
above, (13) a site which is of special importance for military
operations in view of its location, either because it is a site that
must be seized or because it is important to prevent the enemy from
seizing it, or otherwise because it is a matter of forcing the enemy
to retreat from it. It should be noted that the Working Group of
Committee III introduced the location criterion without giving
2022 The criterion of ' purpose ' is concerned with the intended future use of an object, while that of ' use ' is concerned with its
present function. Most civilian objects can become useful objects to
the armed forces. Thus, for example, a school or a hotel is a
civilian object, but if they are used to accommodate troops or
headquarters staff, they become military objectives. It is clear from
paragraph 3 that in case of doubt, such places must be presumed to
serve civilian purposes.
2023 Other establishments or buildings which are dedicated to the production of civilian goods may also be used for the benefit of the
army. In this case the object has a dual function and is of value for
the civilian population, but also for the military. In such
situations the time and place of the attack should be taken into
consideration, together with, on the one hand, the military advantage
anticipated, and on the other hand, the loss of human life which must
expected among the civilian population and the damage which would be
caused to civilian objects.
2024 Finally, destruction, capture or neutralization must offer a ' definite military advantage ' in the circumstances ruling at the
time. In other words, it is not legitimate to launch an attack which
only offers potential or indeterminate advantages. Those ordering or
executing the attack must have sufficient information available to
take this requirement into account; in case of doubt, the safety of
the civilian population, which is the aim of the Protocol, must be
taken into consideration.
2025 Some statements and declarations were made with regard to the interpretation of this paragraph in the final discussion or when the
Protocols were signed. The statements related to two points:
a) a specific area can constitute a legitimate military objective in view of its location and the circumstances (Canada, Federal
Republic of Germany, The Netherlands, United States). (14) The
United Kingdom made a similar statement in a plenary
meeting, (15) and repeated this in a written declaration when
b) the paragraph is not intended to deal with the question of damage caused incidentally by attacks directed against military
2026 These interpretations were not discussed during the Diplomatic Conference; nevertheless, they appear to be reasonable. Of course, an
area as described under a) can only be of a limited size. In
addition, this concept is only valid in the combat area.
2027 It should be noted that the expression "a definite military advantage" is very similar to the terms used in Articles 51
' (Protection of the civilian population), ' paragraph 5(b) and 57
' (Precautions in attack), ' paragraph 2 (a) (iii) and (b). These
articles use the expression "concrete and direct military advantage
anticipated". (17) In the draft the ICRC had used the same expression
in both articles: "distinct and substantial military advantage". The
documents of the Diplomatic Conference do not contain any indication
about the reasons why different expressions were preferred. One is
therefore left to analyze the meaning of the words used.
2028 In the case of Article 52
there must be a definite military advantage for every military objective that is attacked. In the case
of Article 57
' (Precautions in attack) ' this condition must also be
fulfilled, but in addition, the military advantage which should also
be concrete and direct must be weighed against the civilian losses
and damage which could result from an attack.
2029 This is a rule which was not contained in the ICRC draft, or at least not in this form. The amendments submitted during the
Conference did not contain it either; it was introduced in the draft
presented by the Working Group of Committee III. (18)
2030 The presumption established here constitutes an important step forward in the protection of the civilian population, for in many
conflicts the belligerents have "shot first and asked questions
2031 When the paragraph was presented to Committee III it contained in fine a phrase which did not meet with general agreement. It provided
that the normal presumption of civilian use for objects would not
apply in contact areas when the security of the armed forces made
such an exception necessary.
2032 The Rapporteur of the Working Group commented on this phrase as follows:
"[...] infantry soldiers could not be expected to place their lives in great risk because of such a presumption and [...]
in fact, civilian buildings which happen to be in the front
lines usually are used as part of the defensive works. The
phrase was criticized by other delegates on the ground that
it would unduly endanger civilian objects to permit any
exceptions to the presumption". (19)
[p.638] 2033 Finally Committee III decided to delete this phrase (20) and since then the paragraph has not been altered except for some
2034 Therefore even in contact areas there is a presumption that civilian buildings located there are not used by the armed forces,
and consequently it is prohibited to attack them unless it is certain
that they accommodate enemy combatants or military objects. Strict
compliance with the precautions laid down in Article 57
' (Precautions in attack) ' will in most cases bring to light the
doubt referred to in this provision or the certainty that it is a
2035 This article was adopted only after long and difficult discussions. Many delegations would have wished for a more precise
definition, possibly containing a list of examples of civilian
objects and military objectives. The Conference preferred a general
definition. The three examples of civilian objects given in paragraph
3 was as far as it was willing to go.
2036 It is true that a more pragmatic definition would have been useful, and the ICRC paved the way for this in the 1956 Draft
Rules. (21) However, it soon became clear that drawing up a list of
military objectives or civilian objects would have raised insuperable
problems, and the ICRC therefore abandoned the attempt.
2037 However, it remains the case that the text adopted by the Diplomatic Conference largely relies on the judgment of soldiers who
will have to apply these provisions. It is true that there are
clear-cut situations where there is no possibility of doubt, but
there are also borderline cases where the responsible authorities
could hesitate. In such circumstances the general aim of the Protocol
should be borne in mind, i.e., the protection of the civilian
population. In any case an essential step forward has been taken in
that belligerents can no longer arbitrarily and unilaterally declare
as a military objective any civilian object, as happened all too
often in the past.
2038 During the final debate some delegations remarked that in their opinion the article was insufficiently precise on too many points and
that it would give rise to controversy. (22) Finally one delegation
remarked that, in its opinion, this article, like Article 51
' (Protection of the civilian population), ' could not be made the
object of reservations as it is fundamental. (23)
