Paper prepared for “Law’s Imperative: A World Free of Nuclear Weapons” educational
forum, April 2, 2014. Summarized in part and updated from papers given at conferences:
IALANA (International Association of Lawyers Against Nuclear Arms), San Jose, Costa
Rica, 2008; and The Simons Foundation and IALANA Conference, Vancouver, 2011.
First of all, I’d like to say what an honor it is to talk on good faith at this event forPeter Weiss, who has devoted so much of his life to working in good faith for human rights
and for a world free of nuclear weapons.
1. The concept of good faith as found in historical sources and varied traditions
Good faith is paradoxically elusive to define except by its absence. It has beenrecognized as a concept, however, and practiced by most traditions since ancient times. It
is suggested that good faith, in the sense of trust, evolved from prehistoric times. A
minimum of human co-operation and tolerance is necessary if group living is to emerge
and survive. Membership of any human group involves obligations, and even the earliest
human groups must have required the performance of obligations assumed or imposed on
the members of those groups. The notion of obligation postulated here can be expressed in
the sense that a member of the group was ‘trusted’ (that is, relied upon) to perform
whatever task was ‘entrusted’ to him”(1).
In ancient India, the concept of good faith is implicit in the Sanskrit word dharma.
There is no single word that conveys all meanings of dharma, but ‘duty, law’, ‘obligation’,‘proper action’ and ‘right behavior’ have been used. Dharma was part of Hindu, Buddhist,
Jain, and Sikh traditions, referring to the Vedas on legal and religious duties, and codified
in the Hindu text Dharmasastra. The Sanskrit term ahimsa, non-violence, practiced in
Buddhist, Hindu, and especially in Jain traditions, may also be viewed as related to goodfaith and dharma: as was said in the Mahabarata, “Whatever is attended with ahimsa, thatis dharma.” (2).
In ancient China, good faith may be inferred in tenets of Confucianism equating
individual morality with good government. As Confucious said, “to govern (‘cheng’) is to
set things right (‘cheng’). If you begin by setting yourself right, who will dare to deviate
from the right?”(3). In Japan, Prince Shotoku (574--622), influenced by Buddhism andConfucianism, wrote that “good faith is the foundation of right”(4). Good faith is impliedin the flexibility of the Chinese word fazhi, which means both “rule of law and ‘rule bylaw.’(5).
In ancient Iran, good faith may be inferred in the Avestan peoples’ observance ofasha, with its ethical implications for conduct that included truth, honesty, and loyalty.
Lawmakers and priests upheld the sacredness of a man’s given word, and the importance1

of this as a vital aspect of asha. Two kinds of promises were recognized: varuna, a solemn
oath, and mithra, a mutual agreement between two parties.
In an Islamic tradition from the 14th century, good faith may also be inferred incertain tenets of Fiqh (jurists’ law) which is “independent of the state, has as object
individual conscience and acts, aims for transcendent truth but is aware ofmultiple...alternative estimations of that truth, enforces one in specific cases while
acknowledging the potential truth of others.”(6)In Jewish tradition, the Hebrew term tom lev conveys the concept that good faith
may be shown even if a wrong act is based on an honest mistake of fact. “Tom lev... forms
a central part of.. modern, Israeli law…most important of [these being the Contracts, with
two specific laws on good faith] yet extends the duty to act in good faith...to legal acts
other than contracts and to obligations that do not arise out of a contract.” (7).
European concepts of good faith originated in the teachings of Greek philosophersand Roman jurists. Heraclitus of Ephesus invoked Diké, goddess of Justice, in support ofgood faith: “she shall overtake the artificers of lies and false witnesses”. Socrates, as
Cicero said, was “the first to call philosophy down from the heavens and set her in thecities of men.” Good faith is also implicit in The Laws, in which Plato wrote thatknowledge of the Good is discoverable through reason. He applied this doctrine to the lawof the State in the sense of a fundamental law of right. Tenets of Greek Stoic thought were
important for good faith, such as that the world is a product of reason, and that all laws ofnature aim to reasonable ends. Also, while all men are free and equal individuals, they arealso members of a common humanity.”(8).
In ancient Rome worship of the goddess Fides, personifying Trust, was tied to thekeeping of pacts and treaties. There were two strands, public and private; the former, fides
pubblica, focused on public and international aspects. The latter, fides, focused on the oldidea of honor. In the 3rd century B.C. a system evolved in Rome allowing a magistrate to
adjudicate a claim by the principle of contractual good faith (ex fide bona). From c. 27
B.C. bonae fidei iudicia (the laws of good faith) were accepted as part of the ius civile(civil law). The general standard of bona fides was linked to concepts of natural law and toius gentium (law of the people or country). The rules of good faith were seen as belonging
to the ius gentium and introduced into positive law rules observed in nations generally.
Pacta sunt servanda (‘pacts are to be observed’ ) was regarded as a universal rule, dictatedby natural reason, and formulated by the jurist Justinian as: “What is so suitable to thegood faith of mankind as to observe those things which the parties have agreed upon.” (9)Christianity absorbed Hellenism, Oriental law and ancient philosophy, notably
Platonism. Tertullian, a Roman jurist, is viewed with Clement and Origen as early
Christian apologists...the synthesis of Judeo-Christianity with Graeco-Roman
philosophy...was important for good faith.. The association of Christianity with bona fides
invested the Roman concept with elements of the greater earlier civilizations...because of
the debt which Christianity owed to Judaism and the Hebrew prophets. The civilizations of2

Egypt, Sumeria, and Babylon also valued the concept of good faith. A key aspect of bonafides becoming Christianized was the idea of good conscience. Canon law, developed by
the Church for its own governance, coexisted with Roman civil law, but there wasoverlapping jurisdiction, and before the Reformation it was common to find ecclesiasticalcourts exercising civil jurisdiction. (10)Sources of canon law were collected in 1139 in the Decretum by Gratian at
Bologna; and generally used in universities and Church courts. Lex naturae (the law ofnature) for Church Fathers was both natural and of divine origin. Canon law, developed
over the next centuries, continued to be concerned with concepts of good faith and equity
which early canonists took from Roman jurists and applied to their theory of contracts.
Scholasticism developed in the twelfth century; St. Thomas Aquinas, viewed as thegreatest Scholastic, posited the doctrine of an obligation of the natural moral law. It wasFrancisco Suarez (1548--1617), however, whose views on good faith contributed more tomodern legal theories of good faith. Suarez held that the observance of good faith pertains
to natural law and that an obligation imposed by good faith relates to its proper subject
matter. At the close of the Middle Ages good faith was perceived in Western Europe as auniversal ethical principle in philosophy, derived from natural law. In positive law, it wasreflected in specific rules incorporating good conscience, fairness, equitable dealing andreasonableness.(11)
Hugo Grotius (1583--1645) the great Dutch jurist, praised good faith in theaftermath of the Thirty Years’ War. He was influenced by thinkers of antiquity, yet greatly
advanced natural law concepts of modern public international law. Grotius wrote that
“good faith should be preserved.. for other reasons [and] that the hope of peace may not bedone away with”, for not only is every state sustained by good faith, as Cicero declares,
but also that greater society of states. Aristotle truly says that if good faith has been taken
away, all intercourse among men ceases to exist… [in] Seneca’s phrase , ‘it is the most
exalted good of the human heart…This good faith supreme rulers of men ought...tomaintain, as they violate it with greater impunity; if good faith [is] done away with, they
will be like wild beasts whose violence all men fear... Augustine says that it is right tomaintain the pledge of faith given to an enemy, for under the character of enemies men do
not lose their right to the fulfillment of a promise, a right from which every one possessedof reason is capable of.”(12)In African customary law the principle and practice of good faith is deeply
ingrained in dealings between tribes, in customary law relating to warfare and peace
negotiations. In New Zealand, Maori law also has a strong tradition of good faith inrelation to the observation of treaties(13). Good faith is also integral to Native American
traditions in which ‘”Justice and equality were woven, like the strands of a blanket, deep
into the fabric of traditional society by such great teachers as Aionwantha (Hiawatha), thePeacemaker and Jikonshaseh of the Hodenasaunee (Iroquois Confederacy), theKaienerekowa, the Great Law of Peace…” (14)3The idea and practice of good faith has such long and deep roots in prehistoricand historic times and throughout varied traditions that the foregoing brief account ismerely descriptive rather than comprehensive.
2. Negotiation in good faith as interpreted by international arbitration and in cases
brought to the International Court of Justice (ICJ).
The element of good faith, in the judicial context of international negotiations, hasbeen more difficult to define and uphold. A conduct of good faith is implicit in the duty tonegotiate (i.e. any negotiation is invalid without this) and yet an objective standard to
uphold this duty of conduct has remained refractory. Judicial concerns about specificaspects of good faith negotiation, however, may be seen in a review of the following fivecases, either settled by international arbitration or brought before the ICJ.
Flexibility, willingness to compromise, and a temporary suspension of parties’
rights during negotiation were aspects of good faith valued by the arbitration tribunal in
Lac Lanoux (1957). In this case, a project for the use and diversion of stream waters, thetribunal built its whole decision around the concept of negotiations in good faith, in thecontext of neighborhood law. The fundamental process of negotiation in good faith isdescribed by the tribunal as one whose purpose is placed in equilibrium with the interestsin the conflict (15). “The State has, by rules of good faith, the obligation to take into
consideration the different interests in attendance, to look to them to give all satisfaction
compatible with the pursuit of their own interests and to show that it has, as its subject, areal care to reconcile the interests of the other riparian owner with its own interests. It is anorm that, when taking into consideration adverse interests, one party not show
intransigence on all these rights..for a negotiation to unfold in a favorable climate, it isnecessary that the parties agree to suspend, during the negotiation, the full exercise of theirrights.(16). The tribunal also described traits of the converse, bad faith: “The reality of theobligations thus undertaken is incontestable and sanctions can be applied in the event..ofan unjustified breaking off of the discussions, abnormal delays, disregard of the agreed
procedures, systematic refusals to take into consideration adverse proposals orinterests.”(17)A concern for substance and purpose, not mere formalism, as an aspect of goodfaith in negotiation was emphasized by the ICJ in the North Sea Continental Cases (1969).
The Court was asked to indicate the rules and principles of applicable international law for
the delimitation of the Continental Shelf, between states whose shores were adjacent. The
Court considered that by virtue of customary law the parties’ first duty was to negotiate an
accord , and stated further that “[t]he parties are held to the promise of a negotiation with aview to realizing an accord and not simply to proceed with a formal negotiation as a sort ofpreliminary condition, to the automatic application of a certain method lacking inagreement; the parties have an obligation to conduct themselves in such a manner that thenegotiation has meaning, which is not the case when one of them insists on its own

4position without envisaging any modification.”(18).
Fairness between the parties and consideration for each others’ laws and interests
were focused on by the ICJ, as aspects of good faith in negotiation, in the cases of theCompetence in the Matter of Fisheries (1974), which concerned disputes between Iceland,
the United Kingdom and Germany over fishing rights. The Court directed the Parties tonegotiate and stated that they “had the duty to conduct their negotiations in such a spiritthat each one was obligated, in good faith, to take reasonable account of the laws of theother...to arrive at a fair distribution of ocean resources, based on the data of the local
situation, and taking into consideration the interests of other states who have wellestablished fishing rights in the region”(19).
Sustained maintenance of significant negotiations was an aspect of good faithvalued by the tribunal in the Arbitration between Kuwait and the American Independent
Oil Company (AMINOIL) (1982). In this case the tribunal identified good faith as part ofgeneral principles to which parties, when embarking on a negotiation, are bound tocomply when carrying out an obligation to negotiate, namely “good faith as properly to beunderstood: sustained upkeep of negotiations over a period appropriate to thecircumstances, awareness of the interests of the other party, and a persevering quest for an
acceptable compromise”.(20)The good faith of parties to a treaty, to apply its terms reasonably and in such a waythat its purpose can be realized, was a central concern of the ICJ in the Case Concerning
the Gabcikovo-Nagymaros Project (1997). This case concerned, among other things, a
treaty between Hungary and Slovakia on a joint project of locks and dams, and protracted
disputes between the two countries after unilateral termination of this treaty by Hungary.
The Court invoked the precepts of flexibility and comprehensiveness that it hademphasized in the North Sea Continental Cases, in its directives to the parties: “It is for theParties themselves to find an agreed solution that takes into account the objectives of theTreaty, which must be pursued in a joint and integrated way, as well as the norms ofinternational environmental law.”(21)The Court then turned to its interpretation of the requirements of Article 26 of theVienna Convention of the Law of Treaties of 1969 (VCLT) in this context, and focused on
the second element of good faith: “What is required in the present case by the rule pacta
sunt servanda, as reflected in Article 26 of the VCLT, is that the parties find an agreed
solution within the cooperative context of the Treaty. Article 26 combines two elements,
which are of equal importance. It provides that “Every treaty in force is binding upon theparties to it and must be performed by them in good faith. This latter element, in the
Court’s view, implies that, in this case, it is the purpose of the Treaty, and the intentions of
the parties in concluding it, which should prevail over its literal application. The principleof good faith obliges the parties to apply it in a reasonable way and in such a manner thatits purpose can be realized.”(22)The conduct of the parties during negotiations was addressed by the ICJ in

5

Macedonia v. Greece in 2011. The Court said that “Whether the obligation has been
undertaken in good faith cannot be measured by the result obtained. Rather, the Court must
consider whether the parties conducted themselves in such a way that negotiations may bemeaningful”. (23)Such traits of good-faith negotiation are egregiously absent in the context of thedisarmament obligation of NPT Article VI.

--Article 31(3), The Vienna Convention on the Law of Treaties
4. Good Faith and the Negotiating History of the NPT
In 1945 good faith was a bedrock principle of the U.N. Charter, as noted above,and imposed on all member states a general obligation of disarmament. In 1946 the first
resolution of the U.N. General Assembly called for a commission for the elimination of
atomic weapons and other weapons of mass destruction. There were similar General
Assembly resolutions in 1954, 1963 and 1965.
In 1968 the element of good faith was explicitly set forth in Article VI of the
Nuclear Non-Proliferation Treaty, which states:“Each of the Parties to the Treaty undertakes to pursue negotiations in good faithon effective measures relating to cessation of the nuclear arms race at an early date and to6

nuclear disarmament, and on a Treaty on general and complete disarmament under strict
and effective international control.”The placement of the term ‘in good faith’ directly after the word ‘negotiations’points to a clear interpretation of the former as modifying the latter, as an adverbial phrase
directing how negotiations are to be pursued, i.e. in a specific way: in good faith.
Moreover, good faith negotiation as an integral part of the subject matter of all threeobjectives—effective measures relating to 1) cessation of the nuclear arms race 2) nuclear
disarmament and 3) a treaty on general and complete disarmament—should be interpreted
as extending to the second and third obligations in which good faith is implied, as well as
the first, in which good faith is explicitly stated. This would comport with the good faithrequirement of the first part of Article 31(1) of the VCLT, that a treaty should beinterpreted “in accordance with the ordinary meaning to be given to the terms of the treaty
in their context.”
By 1964 five states--the U.S, the Soviet Union, France, the U.K, and China--hadnuclear weapons. In negotiating the NPT, good faith was necessary among all parties-states possessing nuclear weapons, and those without them--if a treaty of such magnitudeand complexity was to be concluded. The exercise of good faith, as both a hortatory
standard and a pragmatic tool, was incumbent on all party representatives, as shown in U.N
General Assembly Resolution 2028 in November 1965. This called on the Conference of
the Eighteen-Nation Committee on Disarmament to negotiate an international treaty basedon five main main principles.
While good faith was implicit in all these principles, Principle (c) : the Treaty
should be a step towards the achievement of general and complete disarmament and, moreparticularly, nuclear disarmament; had direct relevance for nuclear disarmament. In
Principle (b): the Treaty should embody an acceptable balance of mutual responsibilities
and obligations of the nuclear and non-nuclear powers--the exercise of good faith was also
linked, implicitly but closely, with nuclear disarmament.
Judge Mohammed Bedjaoui, president of the International Court of Justice from1994--1997, wrote a profound essay in 2007 on good faith and nuclear disarmament. He
linked good faith with equity by noting that “in substance, in the spirit of the NPT
negotiators, Article VI, which lays out the obligation to negotiate nuclear disarmament ingood faith, was clearly conceived as the necessary counterpart to the commitment by the
non-nuclear states not to manufacture or acquire nuclear weapons; it is without a doubt oneof the essential elements of the ‘acceptable equilibrium of mutual responsibilities between
nuclear powers and non-nuclear powers’ established by the Nuclear Non-Proliferation
Treaty 1965. In 1995, which decided the extension of the NPT for an indefinite duration,
the reciprocal nature of the said obligations was vigorously reaffirmed.” (24)
In 1996 the obligation of good faith negotiation in Article VI of the NPT was
significantly strengthened by the International Court of Justice in its Advisory Opinion on
the Legality of the Threat or Use of Nuclear Weapons that7

“There exists an obligation to pursue in good faith and bring to a conclusion
negotiations leading to nuclear disarmament in all its aspects under strict and effective
international control.”
The imperative to negotiate in good faith, as well as the need for flexibility, can beinferred by the Court’s interpretation 1) that good-faith negotiation goes beyond an
obligation of conduct to one leading to a precise result and 2) an obligation of good faithnegotiation is required--found in the NPT and in evolving customary law norms of nonpossession-- on all aspects of nuclear disarmament. Two significant aspects of latter arethat for the first time the Court clarified that this obligation a) is to achieve the complete
elimination of nuclear weapons, without any precondition of comprehensive
demilitarization and b) extends to all states, even those currently non-parties to the NPT.
Regarding the obligation to conclude negotiations, “the Court relied [in Article VI]
on a distinction in international law between two kinds of obligations. [the first is one of]conduct, which refers to performing or refraining from a specific action. The second...is[one] of result: a state by which some means of its choice is required to bring about acertain outcome. The ICJ said that Article VI involves both kinds of obligation’’. ¶99 of
the Opinion, stated that “the legal import of that obligation goes beyond that of a mere
obligation of conduct: the obligation involved here is an obligation to achieve a precise
result, nuclear disarmament in all its aspects, by adopting a particular course of conduct,
namely the pursuit of negotiations in good faith.” (25)
5. The imperative of good-faith negotiation on Article VI in intervening andsubsequent agreements and commitments.
The 1995 NPT Review Conference adopted Principles and Objectives to measurecompliance with the disarmament obligation pursuant to the Treaty’s indefinite extension.
These included the negotiation by 1996 of a Comprehensive Test Ban Treaty,commencement of negotiations on a Fissile Material Cut-Off Treaty, and the “determined
pursuit by the NWS of systematic and progressive efforts to reduce nuclear weapons
globally, with the ultimate goal of eliminating those weapons”.
The 2000 NPT Review Conference adopted Thirteen Practical Steps, including “anunequivocal undertaking by the NWS for the total elimination of their nuclear arsenals, theurgency of an early entry into force of the CTBT, the need for a body in the Conference on
Disarmament to deal with nuclear disarmament and to start negotiations on an FMCT,
further progress by all NWS on nuclear disarmament by specific steps such as increasedtransparency, irreversibility, and a diminishing role for nuclear weapons in security
policies. Acceptance of these and other steps is inferred by their inclusion in a Final
Document and by prior agreement of NPT Article VIII, to review the operation of theTreaty to assure that the objectives of the Preamble and the Purposes of the Treaty arebeing realized.”
In 2005 the “Renewed Determination” of the 2005 U.N. General Assembly8Resolution, restated approvals of the principles of transparency and irreversibility from the2000 Review Conference and made new statements such as the need for a reduction of theoperational status of nuclear weapons systems.
Lack of good faith is clear in such aspects as the blatant disregard by the NWS of‘systematic and progressive efforts’ to comply with their ‘determined pursuit’ of goodfaith negotiations from the 1995 NPT Review Conference, and their continuing disregardof their pledge from the 2000 NPT Review conference of an ‘unequivocal undertaking forthe total elimination of their nuclear arsenals.
6. Statutory and Scholarly interpretations of Good Faith Negotiation
Statutory interpretations of good faith give relevant insights. The Special
Rapporteur, in writing about the drafting of Article 26 of the VCLT on the obligation thatevery treaty in force must be performed by the parties in good faith, stated that in relation
to this provision, “the intended meaning was that a treaty must be applied and observed not
merely according to its letter, but in good faith. It was the duty of the parties... not only toobserve the letter of the law but also to abstain from acts which would inevitably affecttheir ability to perform.” (26)This implies that a signatory state may violate its obligation to perform a treaty
even if it does not violate its literal terms. “A State may take certain action or be
responsible for certain inaction which, though not in form a breach of a treaty, is such thatits effect will be equivalent to a breach…in such cases a tribunal demands good faith andseeks for the reality rather than the appearance.”(27). This is certainly relevant to the lackof good faith shown by the NWS, and by the U.S in particular, in their inaction andobstructions in negotiation on nuclear disarmament since the 1996 Advisory Opinion was
rendered.
Regarding Article 31(3) of the VCLT, good faith, while not explicitly stated, is
implicit in the provision when the Article is read as a whole, and has particular import ininterpreting the links between the obligations and performance of Article VI. One writernotes the close link in treaties “between the obligation itself and its performance—for eveninterpretation as presented is not an exercise in abstraction but has an essential functionalrole in the decision-making process of a party or of a court or tribunal as regards theperformance of the obligation...[the essential function of good faith in this context] is to
give a broad interpretation of the scope of equitable principles.”(28).
Antonio Cassese, a noted international law jurist, discusses distinctions between
two categories of good faith obligations in international negotiations.. Pacta decontrahendo “[are] obligations to conclude agreements [in which] the contracting parties(1) clearly lay down an obligation to conclude an agreement, and...(2) outline the basic
content of the future agreement...they make it incumbent upon the parties to agree upon a
specific legal regulation of the matter outlined in generic terms in the pactum. Since theparties must act in good faith...if one of them refuses to make the agreement or finds

9

pretexts for delaying its conclusion, it is in breach of international law. Pacta denegotiando [are] obligations to negotiate future agreements [imposing a] binding
obligation...although here the content of the obligation is [simply that the Parties are] dutybound to enter into negotiations. However, both parties [may not] 1) advance excuses for
not engaging in or pursuing negotiations or 2) to [act so as to] defeat the object andpurpose of the future treaty. On this point international case law is very clear and always
demands full observance of good faith.” (29).
Judge Bedjaoui interprets the obligation outlined in NPT Article VI as a pactum denegociando “but one of a particular type...the obligation to negotiate in good faithstipulated here is shown to be a true international obligation requiring its subjects to adopt
a specifically determined conduct...it is also specific in its purpose insofar as it
concerns...nuclear disarmament... The extreme importance of the stakes for humankind in
the issue of nuclear disarmament therefore requires the utmost rigor in assessing theprotagonists’ conduct regarding the obligation to negotiate such a disarmament in goodfaith. ”(30)
7. Good Faith Negotiation and International Humanitarian Law
The last few years there has seen an evolving recognition of the imperative of
good-faith negotiation on NPT Article VI to uphold international humanitarian law. The
latter, which evolved from the Hague Conventions of 1899 and 1907 and from the four
Geneva Conventions of 1949 and their Additional Protocol of 1977, is a set ofinternational rules established by treaty or custom, which addresses humanitarian issues
directly arising from armed conflicts, and limits the rights of the parties to a conflict to use
methods and means of warfare of their choice.
In 2007 Judge Bedjaoui wrote, “ nuclear weapons seem to me absolutely of anature to cause indiscriminate victims among combatants and non-combatants alike, as
well as unnecessary suffering among both categories. The existence of nuclear weapons istherefore a major challenge to the very existence of humanitarian law, not to mention theirlong-term harmful effects on the human environment, in respect to which the right to life
can be exercised. In international relations, states which are supposed to act in good faith
are obliged to take into account, in their behavior, their respective legitimate expectations.
Each of them has with respect to the others a right, created by good faith, not to be
deceived in these expectations. Good faith thus gives birth to rights.”(31)In May 2010 for the first time the NPT Review Conference expressed for the firsttime its “deep concern at the catastrophic humanitarian consequences of any use of nuclear
weapons and reaffirms the need for all states at all times to comply with applicableinternational law, including international humanitarian law.”(32) I
In November 2011 the Council of Delegates of the International Red Cross and Red
Crescent adopted a resolution in which the Council emphasized the incalculable sufferingresulting from any use of nuclear weapons, the lack of any adequate humanitarian response10capacity and the absolute imperative to prevent such use. The Council also found it hard tosee how any use of nuclear weapons could be compatible with rules of international
humanitarian law, in particular those of those of distinction, precaution, andproportionality. (33)
The rule of Distinction prohibits the use of weapons which are unable todistinguish between combatants and civilians; and the rule of Proportionality prohibits theuse of weapons whose collateral effects on civilians are disproportionate to the militaryadvantage of the anticipated attack.
Good faith is implicit in the rule of precaution, which requires that measures betaken in advance to comply with the rules of distinction and proportionality. As stated in a2005 study by the International Committee of the Red Cross, all feasible precautions must
be taken to avoid, or at least minimize, incidental loss of civilian life and damage to theenvironment. (34)
A corollary of the latter is the need for good-faith negotiation on NPT Article VI toprevent ecocide: scientific studies increasingly indicate that a nuclear war--even a limited
nuclear exchange between India and Pakistan--could result in massive climate changes
such as tons of soot lofting into the stratosphere, depleting the ozone layer and causing“widespread damage to human health, agriculture, and terrestrial and aquatic
systems...(t)he combined cooling and enhanced UV would put significant pressures on
global food supplies and could trigger a global nuclear famine.” (35)The rule of precaution, as John Burroughs notes, also has wide implications for thepolicy of nuclear deterrence. The latter involves planning and preparation to use nuclear
weapons in varied situations under great stress. Good faith in applying the rule ofprecaution would show that any use of nuclear weapons could not comply with rules of
distinction and proportionality and thus argue for an end to reliance on nuclear weapons
and for nuclear disarmament.(36)In the U.S., however, the 2010 Nuclear Posture Review pledged billions of dollars
for “sustaining a safe, secure, and effective nuclear arsenal”(37) The 2013 U.S. Nuclear
Guidance reaffirmed a commitment to deterrence and Cold War policies of counterforce
targeting; retaining the triad of land, air, and sea-based nuclear weapons; and retaining
non-strategic nuclear weapons deployed in Europe. The outcome has been some modest
reduction of nuclear weapons under the bilateral U.S./Russian New Start Treaty but
continued reliance on policies that maintain and refurbish nuclear weapons through ‘Life
Extension Programs [LEPS] and those which develop new weapons.
Two examples are the planned Uranium Production Facility and the refurbishmentof the B-61-12 bomber produced at the Y-12 nuclear facility in Oak Ridge, Tennessee. The
recent ‘improvement’ of the latter has a new guided tail kit to increase accuracy andcontravenes the 2010 NPR which pledged that “the U.S. will not develop new nuclear
warheads. Life Extension Programs will use only nuclear components based on previously

11tested designs, and will not support new missions or provide for new military capabilities.”(38)
Since early 2013 Russia has modernized its nuclear forces, including the continued
development and deployment of new intercontinental ballistic missiles, construction ofballistic missile submarines, development of a new strategic bomber, and and deploymentof tactical ballistic and cruise missiles and fighter-bombers.
There are similar nuclear weapons modernization programs in the U.K., France andChina, as well as in Israel, India and Pakistan.
Such nuclear weapons modernization programs by the nuclear weapon statesclearly contravenes the interpretation of VCLT that good faith obliges the parties to atreaty to apply it in such a way that its purpose can be realized, and to abstain from acts
which would inevitably affect their ability to perform.
Further, a delay of more than four decades by the nuclear weapon states inundertaking or even starting negotiations on the nuclear disarmament obligation of NPT
Article VI clearly indicates bad faith in “abnormal delays’ as described by the Lac Lenoux
tribunal, as the NWS have shown a blatant regard for substantive and procedural aspectsof good-faith negotiation: “sustained upkeep of significant negotiations” outlined in the
AMINOIL arbitration.
A common view now is that states like Iran and North Korea are acting in bad faithregarding their nuclear plans, but a wiser and more realistic approach would be to take along-term view of recognizing the complete lack of good faith of the nuclear weapon states
for more than four decades in complying with the nuclear disarmament obligation of NPT
Article VI.
Good faith, in the sense of trust, is a core value of civilization and essential to any
negotiation. It is key to further negotiation on NPT Article VI., which is an urgent andessential international obligation. The continued existence of weapons, which inflict
unique injury and unnecessary suffering, are unnecessary for security purposes, risk
environmental catastrophe and ecocide, use vast amounts of the world’s resources that
could otherwise be used for humane purposes and prevent the attainment of a more
equitable world--is an annihilation of good faith principles, is a major challenge to the very
existence of international humanitarian law, as Bedjaoui writes--and undermines all
international law.
Good faith negotiation on NPT Article VI is thus essential to uphold international
humanitarian law and urgently needed to lead to a verifiable, equitable and irreversible
Nuclear Weapons Convention for the attainment of a fair and sustainable world free of
nuclear weapons.
