How the ranking was prepared
The selection has been prepared through an independent editorial analysis and an overall assessment of the track record, specialisation, experience and professional recognition of the lawyers included. Multiple sources of information have been taken into account, including the professionals' and their firms' websites, news and publications in the media, matters and transactions in which they have participated, their academic and institutional activity, their national and international profile, and references within the legal and business communities.
Particular attention has also been paid to the perception of clients and professionals familiar with their work, assessing factors such as the confidence they inspire, responsiveness, legal judgement, effectiveness in resolving matters and the recognition achieved within their respective areas of specialisation. The result reflects a combined editorial assessment of objective and qualitative factors, intended to reflect not only track record and technical expertise, but also the prestige and professional standing each lawyer has consolidated in legal practice.
