[T]the viewpoint and methodology of Aldo Frignani’s study is by and large that of a comparative lawyer inquiring into similarities and differences between domestic legal systems and supranational rules, within the framework of a global competition to arbitrate. The work’s subtitle – “A Comparative Perspective” – is in fact revealing, regarding both the methodology adopted and the variety of sources considered. As far as the latter are concerned, the work provides an overview of the rules on arbitration contained in all the major domestic legal systems, with a particular focus on the similarities and differences between civil-law and common-law jurisdictions, but also with plentiful information about less widely studied jurisdictions. The sources considered by Professor Frignani, however, are not limited to domestic ones. On the contrary, his work provides a comprehensive overview of all the most relevant supranational sources.
