Much as with crime and punishment, we have only little direct evidence from later prehistory where legal procedure is concerned. Caesar claims that the druids are the judges for all kinds of legal disputes, both where criminal and where civil law is concerned. Where the latter is concerned, the examples Caesar mentions are quarrels over inheritance and boundaries, indicating that such conflicts were seen as particularly important by his sources. That druids were moral philosophers is also known from other historical sources such as Strabo, which may indicate that at least part of the druids was trained as professional lawyers.
