Arbitration, like all forms of dispute resolution, whether formal or informal, is dependent upon the communication and processing of information. Parties communicate with the arbitrator and with each other. The arbitrator invites evidence, evaluates behaviour, and makes decisions. Various rules limit how information may be introduced and employed. This chapter explores the impact of innovative uses of new technologies on the practice and process of arbitration. More particularly, we explore the nature and implications of the shift from reliance on paper and face-to-face approaches, to processes that are technologically supported and either partly online or all-online.
