Guest: Randall Stephenson (Max Planck Institute for the Study of Crime, Security and Law)
For decades, the standard method for comparing legal systems around the world has been under fire. But what if the problem isn’t the method itself, but how we’ve been using it?
On this episode of the Lawcast, Randall Stephenson argues that instead of abandoning our old tools, we need to completely rethink them. By drawing on everything from ancient philosophy to quantum physics, he reimagines law not as a static museum of rules, but as a dynamic, living web of relationships. Get ready for a fascinating conversation on how we view global law.

Guest: Malcolm Jorgensen (Max Planck Institute for Comparative Public Law and International Law)
Imagine you’re on a yacht in the South China Sea. Suddenly, a US destroyer and a Chinese patrol vessel approach. Both claim rights to the same stretch of water; both believe they are following international law. How can two superpowers look at the same body of water and see two different sets of rules?
Join host Christopher Murphy and guest Malcolm Jorgensen as they explore the retreat of the 'rules-based order'. They discuss a world fracturing into spheres of influence, where international law is increasingly defined by the local superpower. It’s a fascinating look at how China, Russia, and the US are competing to rewrite the very definition of global power.

Guests: Johanna Fink & Marc Bovermann (Max Planck Institute for the Study of Crime, Security and Law)
How can a democracy protect and safeguard its core values without inadvertently harming them and becoming an authoritarian state? This crucial legal and political question forms the starting point for this episode of the Lawcast.
Join Christopher Murphy as his guests—Marc Bovermann and Johanna Fink—discuss how Germany has adopted a so-called militant democracy to balance the right to free speech with the state's duty to safeguard its democratic foundations.

Guest: Tatjana Hörnle (Director of the Department of Criminal Law, Max Planck Institute for the Study of Crime, Security and Law)
Beyond a simple ‘yes’ or ‘no’, consent to sexual activity is a nuanced concept deeply intertwined with respect, personal boundaries, and human dignity. As European nations grapple with reforming their sexual assault laws to reflect these complexities, we explore the challenges of creating effective legislation. Christopher Murphy is joined by Tatjana Hörnle, whose expertise in the modernization of these laws across Europe provides invaluable insight into this crucial and sensitive subject.

Guest: Valérie Rosoux (University of Louvain (Belgium) and Max Planck Law Fellow)
Today's episode explores the complexities of mediation in some of the world's most intractable conflicts. Valérie Rosoux joins Christopher Murphy to discuss how deep-rooted animosity and intergenerational mistrust make third-party brokered mediation particularly difficult in such situations.
Given these complexities, what tools can mediators utilize to bring conflicting parties to the discussion table? When is the optimal time for them to intervene (to avoid acting either too prematurely or too belatedly)? And, perhaps most importantly, how can ingrained mistrust and animosity be transformed into a genuine desire for lasting peace?

Guest: Erik Tuchtfeld (Max Planck Institute for Comparative Public Law and International Law)
The Internet connects people from across the globe: it facilitates communication and has single-handedly transformed education, commerce, and entertainment. But who controls what we can say and find on the Internet? Or better put, who are the Internet’s Global Gatekeepers?
In this episode, Erik Tuchtfeld and Christopher Murphy dive into the complex world of online content moderation and discuss its far-reaching implications.

Guest: René Urueña (Universidad de Los Andes in Bogotá (Colombia) and Max Planck Law Fellow)
Is Latin America on the verge of a clash between human rights and the growing influence of Christian Evangelicals? This episode of the Max Planck Lawcast delves into the rise of Evangelical Christianity in Latin America. Join Christopher Murphy and renowned Colombian scholar René Urueña as they explore how this dynamic religious movement is shaping politics, culture, and social issues across the region, including its impact on LGBTI rights and the broader landscape of governance and law.

Guest: Janne Mende (Max Planck Institute for Comparative Public Law and International Law)
This episode delves into the US Supreme Court's 2022 decision to overturn the constitutional right to abortion, a ruling that sparked intense national protest and division. Janne Mende and Christopher Murphy analyse the decision, connecting it to the concept of norm decoupling, which describes the increasing separation of liberal-democratic norms from their traditional interpretations and applications. The discussion then turns to whether the handling of abortion rights in the US is indicative of a more general backsliding of liberal-democratic norms.

Guest: Lara Bucholski (Max Planck Institute for Comparative and International Private Law)
During the years that it was in power, the Nazi regime made far-reaching changes to German civil law, especially family law. Marriage was understood as a societal 'service', children were deemed to be the nation's 'most precious asset', and mothers were idolized as the backbone of society. In today's Lawcast episode, Lara Bucholski details how these civil law changes serve as proof that law is rarely truly neutral as seen by the fact that the value-based jurisprudence of the Nazi regime influenced and modified existing law to its advantage. Thus, although law may be drafted with great precision, significant power remains with those who apply it.

Guest: Raphael Schäfer (Max Planck Institute for Comparative Public Law and International Law)
One of international law’s greatest concerns is ensuring peace. However, sometimes this simply isn't possible. In such instances, the goal of international law then swings towards guaranteeing ‘humane’ warfare and resolving conflicts as quickly as possible.
In today's Lawcast episode, Raphael Schäfer elaborates on the functioning of the laws of war based on their historical context. Although warfare has rapidly evolved over the centuries, the associated death and destruction have not. So what can today’s politicians learn from the politicians of yesteryear when it comes to reining in conflicts before they spiral out of control?
