Michael O. Tackley Partner

Michael is a commercial litigation partner based in London. His practice focuses on international dispute resolution.

A high proportion of his clients are foreign to the UK but need to resolve commercial disputes by litigation in the UK Courts. Resolving an international dispute often requires Michael to coordinate litigation about related issues in multiple jurisdictions.

He has a very strong connection with the Nordic countries and appeared on Icelandic television to comment on a possible claim against the UK government following the use of anti-terrorist legislation against an Icelandic bank.

Michael trained at a firm in the heart of the city of London where he subsequently became a partner. He later set up with others the first Multi-National Partnership after the UK rules changed and he went into partnership with a Danish lawyer. Michael subsequently moved to become a partner in the international practice which became McGuireWoods’ London office.


Defense of Bestnet Europe Limited against an allegation that its directors misused confidential information belonging to the claimant relating to the manufacture of long lasting mosquito nets with insecticide incorporated into the plastic. The parties are all Danish and the case proceeded not only in the High Court and Court of Appeal in London but also in related proceedings in four other jurisdictions. Despite a finding of misuse, the imposition of an injunction on Bestnet’s current product has been effectively resisted and the case is recognized as a leading authority in trade secrets matters.
