Sally Kenney's article on clerks, or "référendaires", on the European Court of Justice (ECJ) provides one detailed point of comparison (2000). There are some major differences between ECJ clerks and their American counterparts, largely because of the way the ECJ is structured. One key difference is that ECJ clerks, while hired by individual judges, serve long tenures as opposed to the one-year-clerkship norm at the U.S. Supreme Court. This gives ECJ clerks considerable expertise and power. Because ECJ judges serve six-year renewable terms and do not issue individual opinions, the most important role of ECJ clerks is to facilitate uniformity and continuity across chambers, member-states, and over time.
