The first presentation, “Non-Fiscal Tax Policies and State Sovereignty” was delivered by Giulio Allevato, who is a professor at the law faculty at IE University in Madrid and is also affiliated with the Bocconi School of Management in Milan. In his talk, Giulio focused on the intersection of tax policies and national sovereignty, offering new perspectives into how non-fiscal tax policies impact state autonomy in a globalized world. His talk was critically reviewed by Tracy Kaye, a distinguished law professor at Seton Hall in New Jersey, who gave insights on the US perspective on taxing MNE’s and potential tax policy shifts under the upcoming Trump administration. The second presentation, “A Game of Give and Take? Public Expenditure and Tax Legitimization” was given by Christine Osterloh-Konrad, professor and dean of the law faculty at the University of Tübingen. Christine’s lecture examined the different dimensions of tax legitimization with regards to the ability-to-pay principle and the benefit principle. Her presentation was followed by commentary from Anuscheh Farahat, a professor at the University of Vienna, who framed her response around the principle of solidarity highlighting its role in the legitimacy of taxation. Overall, the event successfully brought together leading academics to engage in meaningful dialogue on pressing tax law issues, fostering in-depth discussions, critical analysis, and the exchange of diverse perspectives.
