The Principle of Proportionality Toward Risk Prevention——Based on the Judgment Logic of European COVID-19 Derogation Measures

The COVID-19 pandemic has brought legal challenges to the containment measures adopted by European countries.During the outbreak and containment phase of the pandemic,most European countries adopted measures such as lockdowns and mandatory home quarantines based on the principle of risk prevention.However,Article 15 of the European Convention on Human Rights and judgments by the European Court of Human Rights require such measures to comply with the principle of proportionality.In view of this,this article examines the European Court of Justice’s loose judgments on the derogation measures during the pandemic,and the European Court of Human Rights’situational judgments in this regard.Based on the analysis of the legitimacy of the principle of risk prevention and the principle of proportionality in responding to public health emergencies,this article prudently examines and predicts the trend of applying the principle of proportionality of risk prevention for the European COVID-19 derogation measures from three perspectives of legitimacy,necessity,and feasibility.

On the Special Application of the Principle of Proportionality under Emergency State

As the two fundamental aspects of modern society,the emergency state and the routine state are not exceptions to the rule of law.They just abide by special legal rules and must adhere to the spirit of the rule of law,such as human rights protection and power restrictions and apply the principle of proportionality.In a state of emergency,public interests are faced with major and urgent threats.In this state,the positioning of the purpose,the examination of the consequences,or the measurement of the legal benefits of the purpose and the consequences all have a certain degree of particularity and complexity.In order to increase the rationality of the principle of proportionality in the state of emergency,and to perform its value function scientifically and effectively,it is necessary to adopt loose application standards based on the characteristics of the state of emergency,grasp the key application links,and limit the scope of application to the review of the rationality of the exercise of emergency powers.Judgment of the legitimacy of the purpose of the exercise of emergency powers and the derogation of civil rights such as human dignity are not within the scope of the principle of proportionality.

An Academic Summary of the International Conference Series on “The Role of the Proportionality Principle in the Pandemic Prevention and Control”

Against the background of a complicated global pandemic situation and normalized pandemic prevention and control in China,leading human rights scholars from China,North America and Eurasia conducted fruitful discussions on the human rights jurisprudence during pandemic through the lens of the proportionality principle at the Sixth Session of the International Seminar Series on"Global Pandemic Prevention and Control and Human Rights Protection",which was organized by the Center for Human Rights Studies of Renmin University of China,under the guidance of the China Society for Human Rights Studies.Focusing on the pandemic-related human rights conditions and legal challenges in global context,participating scholars examined the role of the proportionality principle during the containment of COVID-19 in six topical dimensions,including the normative utility,practical logic,reasonable limits,necessary measures,balancing of interests,and proportional jurisprudence in the post-pandemic era.In oder to cohere human rights jurisprudence for the development of a global community of health for all,this international seminar fostered five fundamental proportionality consensuses from five interrelated perspectives,involving human rights—rule of law—balance—contexts—trends".

Rethinking the Method and Function of Proportionality Test in the European Court of Human Rights

Strasbourg’s application of proportionality test has some unique features.Due to the Court inherent subsidiary role,it hardly transplants the formulas and criteria adopted by the German Constitutional Court or Court of Justice European Union(CJEU) in the complete sense.Consequently,the Strasbourg application of the proportionality has been depicted as a "mysterious house" for the reason that it lacks of certainty.Therefore,some scholars often worry the application of the proportionality test will threaten the predictability and the Strasbourg rule of law.Generally,the proportionality test has two internal functions for the Strasbourg judges:(1) strike fair balance between/among the competing interests;(2) testing on the reasonableness and appropriateness between the measures employed and aim pursued.In the first category,the primary task of the Court is to protect the scope of "essence" of the Convention rights from the interference of collective goods relying on the interest-based rights theory.Beyond this scope,the Court would have to balance the interests explicitly incorporated into the Convention rights as well as the external collective goods claimed by the state authorities.In some sensitive judgments,the Strasbourg Court tends to impose the onerous responsibility of "burden of proof" to the State authorities,or strategically defers to the domestic decisions unless they will be found "manifestly unreasonable".Secondly,the Court must take a scrutiny towards the appropriateness between the means employed and ends pursued,and then it has to decide whether a less intrusive alternative existed or will possibly be found or not.Sometimes,the Court might impose state authorities an obligation looking for a new alternation.However,due to subsidiarity characteristic of the Strasbourg Court,the task of the assessments sometimes is complicated and time-consuming,so the Court are not capable of evaluations in all occasions.Finally,the Court could strike down the "chilling consequence" caused by some few of the legitimate measures which may highly potentially threaten the individual rights in the National legal order.

A Procedure for the Squaring of a Circle (of Any Radius)

This paper presents a graphical procedure for the squaring of a circle of any radius. This procedure, which is based on a novel application of the involute profile, when applied to a circle of arbitrary radius (using only an unmarked ruler and a compass), produced a square equal in area to the given circle, which is 50 cm2. This result was a clear demonstration that not only is the construction valid for the squaring of a circle of any radius, but it is also capable of achieving absolute results (independent of the number pi (π), in a finite number of steps), when carried out with precision.

A Method for the Squaring of a Circle

This paper presents a Method for the squaring of a circle (i.e., constructing a square having an area equal to that of a given circle). The construction, when applied to a given circle having an area of 12.7 cm2, it produced a square having an area of 12.7 cm2, using only an unmarked ruler and a compass. This result was a clear demonstration that not only is the construction valid for the squaring of a circle but also for achieving absolute results (independent of the number pi (π) and in a finite number of steps) when carried out with precision.

The Notion of Efficiency in China’s Civil Law Scholarship

The pursuit of economic efficiency is the major driver for the birth of contemporary Chinese civil law.Contemporary civil law scholarship has demonstrated a serious concern for efficiency from the very beginning.However,many examples suggest that the notion of economic efficiency is often diluted or replaced by factors like civil law doctrinal scholasticism,moral notions,inertial thinking of the planned economy or the will of the leader.It has not been systematically attended to or expressed in a detailed and precise way in the contemporary civil law scholarship in China,rendering some economic judgments uneconomical.In the 21 st century,it is necessary for the civil law studies to establish a clearer and more precise notion of efficiency,to conduct more direct and accurate evaluations on civil laws’incentives on people’s behaviors and their socio-economic effects,so as to reduce the cost of social interactions and promote deeper cooperation and winwin outcome among individuals.

The proportional fairness scheduling algorithm on multi-classes

In this paper, we study resource management models and algorithms that satisfy multiple performance objects simultaneously. We realize the proportional fairness principle based QoS model, which defines both delay and loss rate requirements of a class, to include fairness, which is important for the integration of multiple service classes. The resulting Proportional Fairness Scheduling model formalizes the goals of the network performance, user’s QoS requirement and system fairness and exposes the fundamental tradeoffs between these goals. In particular, it is difficult to simultaneously provide these objects. We propose a novel scheduling algorithm called Proportional Fairness Scheduling (PFS) that approximates the model closely and efficiently. We have implemented the PFS scheduling in Linux. By performing simulation and measurement experiments, we evaluate the delay and loss rate proportional fairness of PFS, and determine the computation overhead.
