One must hope that European supranational and domestic courts will continue to follow the trends highlighted in this book and that lawmakers will adopt legal frameworks which are in compliance with the judicial standards that this book identifies. This is more necessary than ever in a world where, due to ‘global’ emergencies, such as the COVID-19 pandemic, uncertainty and insecurity are fostering limitations on rights and freedoms which are progressively becoming ‘socially approved’, as the editors put it. Social acceptance, however, should not result in departures from the rule of law, which is where courts should continue to step in.
