Proportionality in the Conduct of Hostilities: The Incidental Harm Side of the Assessment

Clarification of international humanitarian law is important in ensuring compliance with the rule of proportionality, but a culture of compliance within armed forces and groups is also crucial.

Summary

  • Military operations are taking place with increasing frequency in densely populated areas. Such operations result in loss of life and harm to civilians, as well as damage to civilian objects, (including infrastructure providing essential services). In order to protect civilians, it is imperative that armed forces and groups comply with the rules of international humanitarian law on the conduct of hostilities, including the rule of proportionality.
  • The rule of proportionality prohibits attacks which may be expected to cause incidental loss of civilian life, injury to civilians, damage to civilian objects or a combination thereof, which would be excessive in relation to the concrete and direct military advantage anticipated. This research paper analyses the key steps that belligerents must take to give effect to the rule, with a particular focus on one side of proportionality assessments – the expected incidental harm.
  • Those undertaking proportionality assessments before or during an attack must consider whether the expected harm will be caused by the attack, and whether that harm could be expected (that is, was it reasonably foreseeable).
  • For the purpose of proportionality assessments, injury to civilians includes disease, and there is no reason in principle to exclude mental harm, even though it is currently challenging to identify and quantify it. Damage to civilian objects includes damage to elements of the natural environment.
  • Once the incidental harm to be considered has been identified, a value or weight must be assigned to it. This is then balanced against the value or weight of the military advantage anticipated from the attack to determine whether the harm would be excessive.
  • In the determination of whether the expected incidental harm would be excessive compared to the anticipated military advantage, ‘excessive’ is a wide but not indeterminate standard.
  • Belligerents should develop methodologies so that those planning and deciding attacks are provided with all necessary information on expected incidental harm, and to assist them in assigning weight to the incidental harm to be considered.
  • If it becomes apparent that the rule of proportionality will be contravened, the attack in question must be cancelled or suspended.
  • Clarification of the law is important in ensuring compliance with the rule of proportionality, but a culture of compliance within armed forces and groups, inculcated by their leaders, is also crucial.

Human Rights Impact Assessment of Trade Agreements

Research Event

26 February 2019 - 6:00pm to 7:30pm

Richard James, Evaluation Co-ordinator, Directorate-General for Trade European Commission
Jennifer Zerk, Associate Fellow, International Law Programme, Chatham House
Chair: Andrea Shemberg, Chair, Global Business Initiative on Human Rights

The idea that trade agreements should be subject to human rights impact assessment has been gathering momentum in recent years. This idea springs from concern – particularly on the part of trade unions and civil society organizations – that states are not presently doing enough to anticipate and address the human rights-related issues that arise from their trading arrangements with other countries.

This meeting will coincide with the launch of a research paper on human rights impact assessment by Dr Jennifer Zerk. It will bring together experts from law, trade policy, human rights impact assessment practice and civil society to take stock of progress so far and consider the future prospects for human rights impact assessment as a risk-analysis and policymaking tool in the trade context.  

The meeting will explore the key risks and benefits of the human rights impact assessment of trade agreements. What legal, political and practical challenges have been encountered so far? In what ways could communication, stakeholder consultation and follow-up of findings be improved? And what is needed to build political and stakeholder support for these kinds of processes?  

This meeting will be followed by a reception.

Chair: Elizabeth Wilmshurst, Distinguished Fellow, International Law Programme, Chatham House

This meeting, supported by the British Red Cross, is the first in a series of three to commemorate the 70th anniversary of the 1949 Geneva Conventions. The meeting will focus on the protection of the wounded and sick in armed conflict and will also include discussion of challenges to the protection of medical care and of health providers.

Attacks on health care personnel and facilities have increased in recent years, as have the instances in which proceedings have been brought against those providing medical care to wounded fighters, including under counter-terrorism measures.

The Geneva Conventions and their Protocols give protection to the wounded and sick and to healthcare providers, but is the law adequate? Is the law sufficiently widely known? How can the law be more fully implemented? What particular challenges arise in non-international armed conflicts?

This event will be followed by a drinks reception.

Cyber Interference in Elections: Applying a Human Rights Framework

Invitation Only Research Event

7 May 2019 - 10:00am to 4:15pm

Chatham House | 10 St James's Square | London | SW1Y 4LE

The use of social media, including algorithms, bots and micro-targeted advertising, has developed rapidly while there has been a policy lag in identifying and addressing the challenges posed to democracy by the manipulation of voters through cyber activity. 
 
What role should international human rights law play in developing a normative framework to address potential harms caused by such cyber activity including the closing down of democratic space, the spread of disinformation and hate speech?
 
This meeting will bring together a small group of academics and practitioners to explore the implications of applying a human rights framework to both the activities of social media companies and the activities of governments and international organizations in seeking to regulate their activity. The purpose of the meeting will be to inform a report that will provide an overview of the applicable law and recommendations for how that law might inform future policy and regulation. 
 
Attendance at this event is by invitation only.

In Judging Prorogation, UK Supreme Court Marks Evolution, Not Revolution, in Law

3 October 2019

Ruma Mandal

Director, International Law Programme
Despite the political significance, last week’s judgment does not signal a newly activist court.

2019-10-03-UKSC.jpg

The UK Supreme Court’s ruling last Wednesday has, at least temporarily, scuppered the prime minister’s plans to limit parliamentary debate before the looming Brexit deadline. Some of the prime minister’s allies have attacked the ruling as a ‘constitutional coup’. But a close reading reveals that the court has stayed within its remit to interpret, rather than make, the law.

In a carefully reasoned judgment, the court emphasized that the case was not about Brexit. But the judges certainly did not shy away from the extraordinary nature of the matters before it, noting that such factual situations have ‘never arisen before and are unlikely ever to arise again… But our law is used to rising to such challenges and supplies us with the legal tools to enable us to reason to a solution.’

The key question before the court was whether the prime minister’s decision to seek prorogation was ‘justiciable’ – i.e. amenable to being reviewed by a court. The English and Scottish courts earlier on in these proceedings had come, dramatically, to opposing views on this.

The Supreme Court was not dissuaded by the inherently political considerations involved in the prime minister’s decision, stating that while ‘courts cannot decide political questions, the fact that a legal dispute concerns the conduct of politicians, or arises from a matter of political controversy, has never been sufficient reason for the courts to refuse to consider it’.

The court went on to emphasize that the Crown’s remaining prerogative powers (exercised on the advice of the government or directly by ministers) have long been subject to judicial scrutiny; such oversight is essential to guarding the separation of powers underpinning the UK’s constitution.

So far, so conventional. The full bench of the Supreme Court was required to grapple, though, with a prerogative power that had never been tested before in the courts. And so they delved back to the 1611 Case of Proclamations: ‘the King hath no prerogative, but that which the law of the land allow him’. In the court’s view, the legal issue to be resolved was the scope of the power to prorogue (the existence of this particular prerogative not being in dispute).

With no case law available to provide direct guidance on this question, the court, instead, relied on two fundamental principles of the UK’s constitution – parliamentary sovereignty and parliamentary accountability. What would be the logical consequence of an unlimited power to prorogue? The ability to shut parliament permanently.

The conclusion: this particular prerogative power had limits. The court held that:

‘A decision to prorogue Parliament (or to advise the monarch to prorogue Parliament) will be unlawful if the prorogation has the effect of frustrating or preventing, without reasonable justification, the ability of Parliament to carry out its constitutional functions as a legislature and as the body responsible for the supervision of the executive. In such a situation, the court will intervene if the effect is sufficiently serious to justify such an exceptional course.’

Having come to this conclusion, the court was left to examine what justification had in fact been given, noting that the prime minister’s motives were irrelevant. It noted that no clear reason had been given – the relevant documents were all concerned with preparing for the Queen’s speech.

Noting evidence on normal practice for such preparations, including from a former prime minister, the court found it ‘impossible… to conclude…that there was any reason – let alone a good reason – to advise Her Majesty to prorogue Parliament for five weeks’.

The court’s decision was neither inevitable nor a radical departure from legal tradition. It represents the gradual evolution of the long-established legal principle that the crown’s powers are set by the law and supervised by the courts.

Courts have traditionally been reticent to rule on prerogative powers which are ‘high politics’ by nature – classic examples include declaring war and negotiating treaties. In recent years, though, the judiciary has shown a growing confidence to grapple with the contours of those prerogative powers that remain. Deference is still shown when looking at how those powers have been used as opposed to the limits of the prerogative in question.

The Supreme Court ruling won’t reassure those who worry about the emergence of an activist court willing to wade (improperly) into the political arena. Nor will it necessarily bring comfort to those anxious about an unwritten constitution in an era where political conventions are fast unravelling.

But divisive court rulings are nothing new, nor are ministerial outbursts about inconvenient judgments. In the current environment, politicians should take particular care not to send mixed messages which undermine the independence of the UK’s judiciary. Public trust in British institutions is dangerously low and the UK can ill-afford further damage to its reputation as a country steeped in democracy and the rule of law.

Online Disinformation and Political Discourse: Applying a Human Rights Framework

6 November 2019

Although some digital platforms now have an impact on more people’s lives than does any one state authority, the international community has been slow to hold to account these platforms’ activities by reference to human rights law. This paper examines how human rights frameworks should guide digital technology.

Kate Jones

Associate Fellow, International Law Programme

Summary

  • Online political campaigning techniques are distorting our democratic political processes. These techniques include the creation of disinformation and divisive content; exploiting digital platforms’ algorithms, and using bots, cyborgs and fake accounts to distribute this content; maximizing influence through harnessing emotional responses such as anger and disgust; and micro-targeting on the basis of collated personal data and sophisticated psychological profiling techniques. Some state authorities distort political debate by restricting, filtering, shutting down or censoring online networks.
  • Such techniques have outpaced regulatory initiatives and, save in egregious cases such as shutdown of networks, there is no international consensus on how they should be tackled. Digital platforms, driven by their commercial impetus to encourage users to spend as long as possible on them and to attract advertisers, may provide an environment conducive to manipulative techniques.
  • International human rights law, with its careful calibrations designed to protect individuals from abuse of power by authority, provides a normative framework that should underpin responses to online disinformation and distortion of political debate. Contrary to popular view, it does not entail that there should be no control of the online environment; rather, controls should balance the interests at stake appropriately.
  • The rights to freedom of thought and opinion are critical to delimiting the appropriate boundary between legitimate influence and illegitimate manipulation. When digital platforms exploit decision-making biases in prioritizing bad news and divisive, emotion-arousing information, they may be breaching these rights. States and digital platforms should consider structural changes to digital platforms to ensure that methods of online political discourse respect personal agency and prevent the use of sophisticated manipulative techniques.
  • The right to privacy includes a right to choose not to divulge your personal information, and a right to opt out of trading in and profiling on the basis of your personal data. Current practices in collecting, trading and using extensive personal data to ‘micro-target’ voters without their knowledge are not consistent with this right. Significant changes are needed.
  • Data protection laws should be implemented robustly, and should not legitimate extensive harvesting of personal data on the basis of either notional ‘consent’ or the data handler’s commercial interests. The right to privacy should be embedded in technological design (such as by allowing the user to access all information held on them at the click of a button); and political parties should be transparent in their collection and use of personal data, and in their targeting of messages. Arguably, the value of personal data should be shared with the individuals from whom it derives.
  • The rules on the boundaries of permissible content online should be set by states, and should be consistent with the right to freedom of expression. Digital platforms have had to rapidly develop policies on retention or removal of content, but those policies do not necessarily reflect the right to freedom of expression, and platforms are currently not well placed to take account of the public interest. Platforms should be far more transparent in their content regulation policies and decision-making, and should develop frameworks enabling efficient, fair, consistent internal complaints and content monitoring processes. Expertise on international human rights law should be integral to their systems.
  • The right to participate in public affairs and to vote includes the right to engage in public debate. States and digital platforms should ensure an environment in which all can participate in debate online and are not discouraged from standing for election, from participating or from voting by online threats or abuse.

The International Criminal Court cannot act when crimes are being genuinely prosecuted in a state. The meeting will discuss whether the ICC complementarity rules apply when a state puts restrictions on the prosecution of war crimes committed in particular circumstances or within a particular time period. In this context, the discussion will also cover the extent to which such restrictions are precluded by international obligations such as those in the Geneva Conventions with regard to the investigation and prosecution of war crimes.

Glucocerebrosidases catalyze a transgalactosylation reaction that yields a newly-identified brain sterol metabolite, galactosylated cholesterol [Glycobiology and Extracellular Matrices]

β-Glucocerebrosidase (GBA) hydrolyzes glucosylceramide (GlcCer) to generate ceramide. Previously, we demonstrated that lysosomal GBA1 and nonlysosomal GBA2 possess not only GlcCer hydrolase activity, but also transglucosylation activity to transfer the glucose residue from GlcCer to cholesterol to form β-cholesterylglucoside (β-GlcChol) in vitro. β-GlcChol is a member of sterylglycosides present in diverse species. How GBA1 and GBA2 mediate β-GlcChol metabolism in the brain is unknown. Here, we purified and characterized sterylglycosides from rodent and fish brains. Although glucose is thought to be the sole carbohydrate component of sterylglycosides in vertebrates, structural analysis of rat brain sterylglycosides revealed the presence of galactosylated cholesterol (β-GalChol), in addition to β-GlcChol. Analyses of brain tissues from GBA2-deficient mice and GBA1- and/or GBA2-deficient Japanese rice fish (Oryzias latipes) revealed that GBA1 and GBA2 are responsible for β-GlcChol degradation and formation, respectively, and that both GBA1 and GBA2 are responsible for β-GalChol formation. Liquid chromatography–tandem MS revealed that β-GlcChol and β-GalChol are present throughout development from embryo to adult in the mouse brain. We found that β-GalChol expression depends on galactosylceramide (GalCer), and developmental onset of β-GalChol biosynthesis appeared to be during myelination. We also found that β-GlcChol and β-GalChol are secreted from neurons and glial cells in association with exosomes. In vitro enzyme assays confirmed that GBA1 and GBA2 have transgalactosylation activity to transfer the galactose residue from GalCer to cholesterol to form β-GalChol. This is the first report of the existence of β-GalChol in vertebrates and how β-GlcChol and β-GalChol are formed in the brain.

Deletion of fatty acid transport protein 2 (FATP2) in the mouse liver changes the metabolic landscape by increasing the expression of PPAR{alpha}-regulated genes [Lipids]

Fatty acid transport protein 2 (FATP2) is highly expressed in the liver, small intestine, and kidney, where it functions in both the transport of exogenous long-chain fatty acids and the activation of very-long-chain fatty acids. Here, using a murine model, we investigated the phenotypic impacts of deleting FATP2, followed by a transcriptomic analysis using unbiased RNA-Seq to identify concomitant changes in the liver transcriptome. WT and FATP2-null (Fatp2−/−) mice (5 weeks) were maintained on a standard chow diet for 6 weeks. The Fatp2−/− mice had reduced weight gain, lowered serum triglyceride, and increased serum cholesterol levels and attenuated dietary fatty acid absorption. Transcriptomic analysis of the liver revealed 258 differentially expressed genes in male Fatp2−/− mice and a total of 91 in female Fatp2−/− mice. These genes mapped to the following gene ontology categories: fatty acid degradation, peroxisome biogenesis, fatty acid synthesis, and retinol and arachidonic acid metabolism. Targeted RT-quantitative PCR verified the altered expression of selected genes. Of note, most of the genes with increased expression were known to be regulated by peroxisome proliferator–activated receptor α (PPARα), suggesting that FATP2 activity is linked to a PPARα-specific proximal ligand. Targeted metabolomic experiments in the Fatp2−/− liver revealed increases of total C16:0, C16:1, and C18:1 fatty acids; increases in lipoxin A4 and prostaglandin J2; and a decrease in 20-hydroxyeicosatetraenoic acid. We conclude that the expression of FATP2 in the liver broadly affects the metabolic landscape through PPARα, indicating that FATP2 provides an important role in liver lipid metabolism through its transport or activation activities.
