Practice Areas

Heiko Haller has represented clients in more than 40 international arbitration cases involving disputes that arise during major infrastructure, construction and IT outsourcing projects. He is particularly experienced in disputes involving large energy projects, such as the construction of nuclear power plants and offshore wind farms.

Heiko's experience working on a variety of cases and solid grasp of engineering concepts have given him a deep understanding of the entire energy chain, from production of raw materials and power generation to energy transmission and storage. This industry knowledge enables him to get up to speed on the technical and commercial aspects of cases quickly, develop winning legal strategies for clients and help them minimize losses or maximize profits.

To help clients make more informed decisions about whether to invest in a dispute and to ensure they get the best return on their investment, Heiko and his team put each case through a risk analysis to calculate the probability that they will prevail on their claims. Heiko also uses this assessment to determine which aspects of the case to focus on and where to invest in expert opinions to achieve the greatest outcome.
