Shareholder & International Treaty Disputes
Navigating Complexities in Shareholder & International Disputes with Clarity and Confidence
Disputes involving shareholders, state-owned enterprises, and investors often intersect legal, financial, and technical dimensions — especially in capital-intensive sectors like construction, real estate, energy, and manufacturing. At MASIN, we bring clarity and credibility to such matters by offering robust financial, delay, and quantum expertise in both shareholder conflicts and treaty-based arbitrations. Our experts have been appointed in highly sensitive, high-value disputes governed under LCIA, SIAC, and UNCITRAL frameworks, including those arising from joint venture breakdowns, loss of profits, investment treaty breaches, and force majeure claims. We help tribunals and counsel untangle complex causation issues and quantify damages with accuracy and independence.
