Since 1st January 1989 Switzerland has a new International Arbitration Act, in the form of Chapter Twelve of the Federal Statute on Private International Law (PILS). In the German version of the Basler Kommentar on the PILS published in 1996, experienced Swiss arbitration practitioners gave a detailed commentary of the provisions on international arbitration. This commentary is now available in an English translation based on drafts by Stephen V. Berti. The book contains a comprehensive, updated introduction to international arbitration by Marc Blessing, followed by: the commentary of articles 176 - 194 PILS by Felix R. Ehrat (article 176); Robert Briner (article 177); Werner Wenger (articles 178 and 186); Wolfgang Peter and Thomas Legler (article 179); Wolfgang Peter and Caroline Freymond (article 180); Nedim Peter Vogt (article 181); Michael E. Schneider (articles 182 and 184); Stephen V. Berti (articles 183, 185 and 193); Pierre A. Karrer (article 187); Markus Wirth (articles 188 and 189); Stephen V. Berti and Anton K.
