Niamh Leinwather, secretary general of the Vienna International Arbitral Centre, has spoken in detail about the institution’s growing international caseload and expanding global reach.
Leinwather appeared on the Arbitration Acumen podcast hosted by J.P. Duffy of Bracewell LLP, covering a wide range of topics facing modern international arbitration.
The Vienna International Arbitral Centre, known as VIAC, is an international arbitration institution based in Vienna, Austria, and has been steadily building its global profile.
VIAC recorded a total of 69 cases on its 2025 docket, with approximately 81 percent of those classified as international disputes, continuing a well-established trend at the institution.
The figures reflect a broader pattern in which international arbitration remains dominant even as domestic arbitration activity at VIAC begins to register gradual growth.
The VIACan ambassador network, which launched in February 2023, has expanded considerably and now counts 54 ambassadors operating across 39 countries worldwide.
Leinwather also outlined plans for the network to extend its reach further, with India and China identified as key targets for future expansion of VIAC’s international presence.
VIAC introduced investment arbitration rules in 2021 specifically designed to provide small and medium-sized investors with an affordable and efficient mechanism for resolving lower-value investor-state disputes.
The conversation also addressed the ongoing debate between transparency and confidentiality, particularly around VIAC’s practice of publishing anonymised arbitral awards and selected extracts for broader legal reference.
Leinwather previewed a new protocol developed by VIAC’s legal tech think tank aimed at helping arbitrators and legal counsel detect deepfakes and identify tampered digital evidence submitted during proceedings.
The emergence of sophisticated digital manipulation tools has placed growing pressure on arbitration institutions to develop formal frameworks for assessing the integrity of electronic evidence.
VIAC’s response, through its dedicated legal tech think tank, signals a wider shift within international arbitration toward proactively confronting technological threats to procedural fairness.
The podcast, part of Bracewell’s Arbitration Acumen series, forms part of a broader effort to examine how leading arbitral institutions are navigating rule reform, technological disruption, and geographic expansion simultaneously.
