Since the current ICC Rules of Arbitration came into force in 1998, over 5,000 cases have been filed with the International Court of Arbitration. These cases are a source of valuable information concerning the application of the Rules, as well as on the responses of ICC arbitrators to the substantive issues in dispute. Over the years, the International Court of Arbitration has sought to make this information available in various ways, one of which has been through the publication of extracts from ICC awards on specific themes in theICC International Court of Arbitration Bulletin. A wide range of themes have already been covered relating to both substance and procedure. They have included-to name but a few examples-tort, banking, insurance, commercial agency, construction contracts and European Community law, as well as conservatory and interim measures, multi-tiered dispute resolution clauses and the correction and interpretation of awards. In the present issue, we focus on the introduction of new claims in ICC arbitration proceedings. This question is governed by a specific provision-Article 19-which was new to the Rules in 1998. The ensuing years have seen a number of awards rendered in which reference is made to Article 19 and so the time is now ripe to take stock of this provision, which we do in this issue by publishing extracts from twenty awards and an accompanying commentary by former Secretary General of the International Court of Arbitration and current Court member, Eric Schwartz.

A broader look at ICC arbitration procedure as a whole will be found in the article on arbitration in Brazil by Cristián Conejero and Renato Grion, members of the Secretariat of the Court. The authors consider how the ICC Rules interact with national law by comparing the provisions of the ICC Rules with those of the 1996 Brazilian Arbitration Law on various aspects of procedure.

The state of national arbitration law is also the subject of the third article published in this issue, which is an overview of arbitration in Yemen by Hamid Gharavi and Lara Karam. The authors look at the principal provisions of Yemeni legislation relating to arbitration procedure and describe the treaty framework relevant to investment dispute resolution in Yemen.

It is hoped that readers will find in these analyses of rules and practice during recent years helpful illustrations and insights.
