The Olympic Committee of Slovenia published the book called "Sponsporship in Slovenian Sport" in June 2022. The publication is divided into legal and economic part of sponsporship. Over twenty lawyers and economists lead by Dr. Tone Jagodic authored the book. I contributed a chapter titled "Athletes' Engagement on Social Media and Obligations Deriving from Contractual Obligations". The book will be presented to the public in October during the "Slovenian Olympic Days".
