During the COVID-19 pandemic, the role of experts, surveys and statistics was put at the forefront of the management of the health crisis in Quebec. This situation gives rise to fears of governance by experts (epistocracy) and by numbers (numerocracy). The analysis of the legislation and cases related to public health measures shows that it is complex to conclude to the existence of epistocracy and numeracy. This article proposes a legal framework for analyzing these normative phenomena, namely that of the law of governance. The law of governance offers another explanation for expertise and information, as these are understood as legitimizing data for decisions made during the health crisis. From this perspective, it is less about governance by experts and numbers, but more about governance with experts and numbers.
