Commercial Litigation

Tyr’s commercial litigation team is led by partners Alistair Kennedy and Matthew Fidler, who specialise in dealing with high value and complex commercial disputes.

The team has a number of key clients and, due to us being largely conflict free, disputes are often referred to Alistair and Matthew by major law firms who trust that their clients will be given the highest quality advice, and attentive and committed representation.

We have experience of all types of commercial disputes, having dealt with claims in the High Court and Appeal Courts, arbitration and mediation, and claims that challenge the decisions of public bodies by way of judicial review, including many cases with an international element and that have attracted significant press attention.

We understand and are ready to meet the needs of commercial clients who are involved in litigation with the potential to transform their businesses.

Alistair has been consistently ranked as one of the leading litigators in the market. He was most recently described in the 2022 edition of the Legal 500 as “combining a remarkable grasp of and attention to detail with an insightful strategic approach” and in the 2021 edition of Chambers and Partners as “a real go-getter who is very switched-on and has a good strategic brain
