IIA Issues Notes are short, online publications that profile a topical IIA-related legal and/or policy question.

They offer a handy and policy-oriented discussion of an issue and aim at facilitating debate and exchange of views among IIA stakeholders. IIA Issues Notes are forward looking; they set the agenda for future research and policymaking.

While topics vary to respond to current developments, one IIA Issues Note annually reports on the number of known treaty-based ISDS cases filed in the preceding year.

This annual review of ISDS cases complements statistical data with a brief description of the most important substantive and procedural issues in arbitral decisions.
