The European Judicial Training Network (EJTN) has produced, with the support of the European Union, a number of great handbooks on legal language, aimed at judicial cooperation across the Member States.
They are free to download, and contain introductions about vocabulary and syntax, summaries of points of law, and exercises for learners on each area, with a glossary and answer key.
I think they may be *very* useful for translators, lawyers working internationally, and many others, in addition to the judges for whom they were originally intended.
