The process by which judicial authorities are selected sets the stage for judicial autonomy and institutional independence. Institutional rules that govern judicial selection – judicial nominations versus direct election, for example – have long been appreciated as an important factor in judicial decision-making, sentencing, and related judicial behaviors. In her important new book Judicial Vetoes: Decision-Making on Mixed Selection Constitutional Courts, Tiede makes a critical contribution to our understanding of these effects in constitutional courts, demonstrating that selection modality is a stronger predictor of both judicial voting and case outcomes than partisanship or ideological leaning in the constitutional courts of Colombia and Chile.
Most constitutional courts around the world disperse the authority to select constitutional jurists amongst several possible actors. Executive branch authorities, legislative majorities, judicial actors, legal system representatives such as the Ombudsman or Attorneys General, members of civil society or the legal profession all may play a role in the selection or appointment of jurists on mixed-selection constitutional courts. The resulting deliberative body then reflects a confluence of jurists who vary in their training, expertise, experience with and allegiance to the selector to whom they owe their nomination. Allegiances thus divided, these constitutional bodies are ensured their independence, such that they might not be beholden to or captured by any external institution or actor.
Tiede meticulously disassembles the historic and legislative record to trace the origins of the mixed-selection system in Colombia and Chile. She shows that the designers opted for a mixed system to both advance their own institutional interests while also dividing said influence across various loci of power. The actors who vet potential judicial nominees do so with an eye for their own institutional priorities and select adjudicators who will best advance the organizational interest while seated on the bench. Prospective judges, for their part, understand these considerations and behave accordingly both to secure the nomination and then advance said interests while in office, cultivating a reputation that will serve their professional career beyond their term on the constitutional court.
Critically, Tiede theorizes these effects at both the level of the judge and in its aggregate, also considering the possible effects that nominating institutions might have for case disposition at the level of both the panel and the Court. Considering only case outcomes would mask the effect of individual judges’ calculus and votes. Conversely, an exclusive accounting of judicial voting without consideration of final decision-making would obscure the effect of facets of collective decision-making (e.g., panel effects and quorum rules). Both can be decisive for outcomes of constitutional adjudication. The mix of selectorate judges impacts not only how individual judges decide cases but is associated with the frequency of constitutional vetoes in the context of abstract review.
