Phillip Ashley is a partner and solicitor-advocate who "specialises in contentious matters relating to the oil and gas and power sectors" and has advised on “matters relating to oil and gas investments in every continent except Antarctica” (Global Arbitration Review).

In June 2016, Phillip was named Rising for Litigation by Legal Week magazine. He is recommended in Legal 500 for international arbitration, commercial litigation and oil & gas disputes. Phillip is also categorised as a "Rising Star" in Energy and Natural Resources by Superlawyers and in IFLR Energy and Infrastructure Sub-Saharan African Guide.

He is internationally recognised as being a specialist in high value energy disputes, including “energy pricing disputes, acting in a series of natural gas and liquefied natural gas price review arbitrations seated in London and Geneva, which were worth around US$10 billion” and “a US$16 billion pricing dispute over a long-term crude oil supply contract” (Global Arbitration Review).

Phillip was called to the bar of England and Wales in 1998 and subsequently cross-qualified to become a solicitor. Prior to joining CMS he was part of the in-house legal team at a leading international engineering, construction and project management company.
