IMS International Arbitration Expertise in Action

IMS has supported some of the most significant arbitration matters across industries such as energy, construction, infrastructure, finance, and real estate. Our teams bring decades of experience helping tribunals absorb the details of technically complex and data-intensive disputes through targeted expert testimony and compelling visual communication.

Featured Case Study: Government of the Republic of Singapore v. Government of Malaysia

Singapore and Malaysia arbitrated at The Hague after Singapore imposed a $1.1 billion development charge on land swapped under a railway treaty, a charge the treaty failed to address. Our team developed an interactive map, animated financial exhibits, and educational visuals that helped arbitrators grasp the complex geographic and valuation issues central to the matter. The development charge at issue was ultimately nullified, demonstrating the power of strategic visual advocacy in international arbitration.
