The present publication can be defined in three words: relevant, original and novel. It is a work divided into four parts, which is immersed in the study of procedural and procedural law for the cross-border litigation in civil and criminal disputes, from a very interesting perspective, mainly for two reasons: originality and critical-constructive character. The book begins with a work on teaching innovation in procedural law in today's globalised, multicultural and interconnected society. The other three parts of the book deal with very new topics in the resolution of cross-border disputes, from the protection of the rights of vulnerable groups, procedural issues such as digital evidence, data encryption, class actions, alternative dispute resolution methods, among many other subjects that shape the resolution of disputes today.
