The future of EU legal integration is at a significant juncture with the departure of the UK, substantial rule of law challenges, internal and external crises, and an increasingly apathetic multilateral legal order. There is increased recognition amongst EU lawyers, who have historically limited themselves to doctrinal analysis and legal hermeneutics, that methodology plays an essential role in order to understand EU integration and shape its future (van Gestel & Micklitz, 2014). Certain schools now advocate that the future of EU law must become more methodologically grounded to realise its scientific benefits and to broaden the reach of lawyers beyond the doctrinal (Dyevre, Wijtvliet & Lampach, 2019). For example, anthropological and sociological approaches have given us a sense of how various national and international actors use EU law to achieve their goals (Vauchez & De Witte, 2013). Quantitative studies have offered new insights into the practices of courts and the effectiveness of legislative design (Larsson and Naurin, 2016; Larsson et al. 2017).
