Applying the Proportionality Principle to COVID-19 Certificates

Abstract

With the SARS-CoV-2 pandemic entering its second year, public and private actors alike grow eager to achieve some semblance of normality. In this context, the idea of vaccination passports or immunity certificates as a means of resuming social and economic activity has been gaining momentum all around the world. This article aims to provide a legal analysis of this initiative through the lens of the proportionality principle. A proportionality test is conducted in order to determine whether the degree of infringement of the human rights implicated is balanced by the potential of a certification system to mitigate the risks of the virus. The results from this analysis show that the targeted aims can be achieved through already existing measures with a lesser impact on civil and fundamental human rights. Moreover, in a context of uncertainty around the immunopathology of COVID-19, the introduction of these certificates presents ethical and scientific challenges, which lead us to believe that this measure is unlikely to play a central role in stopping the spread of the disease, and it could set the pace for a dangerous precedent, allowing for extensive discrimination and exacerbating already existing inequalities and disparities.
