Because arbitrations are private, they often are not published. One of the central challenges facing the researcher is lack of accessiblity of arbitral decisions. However, some arbitral decisions and rules from various arbitral bodies are available via Westlaw. See below. Often, rules and awards are also available via the arbitral bodies' website.
Westlaw's Practical Law platform provides access to arbitral awards and challenges, as well as notes, articles and global guides, written for practicing U.S. lawyers.
