International arbitration is a gigantic global operation, both in terms of number of cases and their commercial value. It takes place in institutional and non-institutional settings, involving both lawyers and non-lawyers. In certain cases, such as in Investor-State Dispute Settlement (ISDS) cases, lawyers have come in for criticism from the UN and the EU. In other cases, there is a patchwork of ethical obligations, sometimes conflicting. The IBA has taken a central role in promoting ethical guidelines. This panel will look at some of the ethical issues arising, which do not appear to be on the radar of the Bars whose members are participating in international arbitration.
