“Peer effects” or “quasi-peer effects” in Spanish labour court rulings

Abstract

The current work seeks to ascertain whether rulings on dismissal cases issued by incumbent judges in Spanish labour courts are influenced by whether they are acting alone in their own court or sharing duties with other judges such as replacement judges, support judges or incumbent judges from other courts. We consider that a court is treated when more than one judge rules in it. Then, an analysis is conducted so as to determine the effect of such a treatment on the percentage of cases ruled in favour of the dismissed worker. The data used in the research are taken from the information recorded at court level provided by the statistics kept by the General Council of the Spanish Judiciary. A total of 2888 observations were available, corresponding to the period spanning 2004 to 2012. As regards the findings, it may be concluded that there is a significant positive impact on the number of dismissal cases ruled in favour of workers when incumbent judges are not acting alone in their court, particularly when the incumbent judge solves cases together with another professional judge.
