Scaling Court Decisions with Citation Networks

To compare court decisions in a systematic way, it is typically necessary to first read these decisions and then apply legal methods to them. Measurement models that support analysts in this manual labor usually rely on judges ’ voting records. Since these data are often not available, weinstead propose a latent-variable model that uses the widely available references in court decisions to measure the decisions ’ latent position in their common case-space. We showcase our model in the context of forum shopping and forum selling of Germany ’ s lower courts.
