Gregory Banner KC

Call: 1989 Silk: 2018

Gregory has a broad litigation practice encompassing company, insolvency, commercial Chancery and commercial work. He has appeared in a number of reported cases, covering a broad range of topics within these areas. He has extensive trial and appellate experience.

He both leads large counsel teams and acts as part of such teams. He has particular experience of international contractual and corporate disputes with either or both of a Russian and natural resources flavour, and which concern fraud and private international law. He has experience of gold mining, refining and trading disputes, oil drilling and trading disputes, and gas exploration matters. He has dealt with such matters in Court in England and in ICC, LCIA and ad hoc arbitrations. His cases have involved in disputes over matters in Moscow, Sochi and Siberia. He has been called ad hoc to the Bar of Bermuda

Closer to home, he has extensive experience of share warranty claims, s994 petitions, board control disputes, insolvency office holders’ claims and investigations, claims for fraud and breach of fiduciary duty. He has many years’ experience of seeking and defending against pre-emptive injunctive and asset protection remedies, as well as pursuing post judgment asset tracing remedies.

Most of Gregory’s cases are document-heavy and high value. He is currently instructed by over 100 claimants in a $150 million claim for restitution against the water companies of England and Wales; he has acted in a $300 million fraudulent misappropriation of assets claim, a dispute over a $400m Russian land development deal, a dispute over a $600m oil trading deal, a dispute concerning a £100m property fund, a $100m land development dispute and a claim over a $500m listed company.

Since taking silk in 2018, his work has included a claim for £30 million based on complex allegations of breach of fiduciary duty in relation to a property investment, conjoined LCIA and ICC arbitrations, seeking recovery of in excess of $100 million and concerning allegations of bribery and agency in the international fertiliser trading markets, a dispute over board control of a listed UK plc with a market capital of £1 billion, a restitution claim against the water companies of England and Wales (above), and a claim to restrain publication of a investigatory report into fraud committed by an employee of a well known international bank.

He has also acted over a period of years for a number of government departments and bodies on contractual and regulatory contentious and non-contentious issues, and as a result has a keen insight into the approach of such bodies to litigation.

He has been recommended in The Legal 500 for insolvency work and in Chambers UK Directory for company work for many years.
