Manolescu offers the first comprehensive study of financial governance as a field where two forces meet: states' decision-making power over a court's funding and the judiciary's need for independence. Through a comparative analysis of seven international courts, the book highlights recurring challenges and best practices, showing that financial governance--the rules, practices, and actors involved in budgetary decision-making and oversight--is not about euros and cents, but about balancing at times competing, seemingly opposite acts of power and control. It provides in-depth insight for academics and practitioners engaged in the budget process or the design of international courts.
