Expert evidence, evaluation, and learning

For investors and asset owners,

we provide authoritative and independent expert testimony on competition, access to essential infrastructure, regulation and quantum of damages matters. We also provide expert analysis to ensure that policies and regulations are well-designed and do not damage business growth and dynamism.

For governments and international agencies,

we evaluate past performance and learn lessons from their own experience and that of other places to inform development of future policies and projects. We also protect their legitimate interest in disputes through expert evidence which ensures that policy and regulatory decisions are fairly evaluated and exaggerated claims for damages are rejected.
