This volume provides an in-depth analysis of cross-border financial disputes within the European Union, exploring conflict, coordination, and competition among various legal systems. Featuring contributions from experts, the book examines how banking disputes, climate change litigation, and derivative disputes intersect with European, international, and domestic regulations. The book highlights the inconsistencies in court-based outcomes before national courts and effective judicial protection, addressing issues such as the liability of collective investment asset managers and the conflicts between public order and private ordering in derivative contracts. It also delves into the emergence of specialized tribunals and the visible trends in judicial protection for financial disputes.
