The last book of the academician Sergij Vilfan entitled »Historical Formation of Law and the Slovenes«, which was published only after his death, deals with the Formation of law among the Slovenian people, a subject that he left aside in his previous fundamental works. This study clearly shows that numerous phenomena that spread among the Slovenes were commonly used and typical for the Central European space, however they carried certain Slovenian characteristics because they were a part of the people's common legal consciousness for centuries. The acadeniician Vilfan believed that these particularities were not part of the »national spirit«, but the result of various historical circumstances. Although very cautious in reaching conclusions, he was nevertheless clearly and argumentatively breaking up a wellrooted conviction as regards a thousand years ofservitude and incapability of the Slovenian people to form their own law. He stated that independent legal development could also take place outside ofthe Roman-Germanic-Slavic scheme. On the basis of numerous examples the author demonstrated that the formation of law had a rieh tradition in Slovenian history. With his final book the academician Vilfan rounded up his work, created a certain synthesis, and presented a final conclusion to his vast research work. It may be said that his death and the publication of this book started a new era in Slovenian legal history, which will build upon Vilfan’s rich scientific legacy and valuable findings. The academician Vilfan was writing this book fully aware of the fact that his time was quickly running out. The book therefore presents a kind of his final testament as it explains the numerous issues that remain open and still need to be researched in order to make the picture of the Slovenian legal history more complete. The purpose ofthe presented article is to shed some light upon these tasks.
