He was the first to obtain in Gibraltar a common law production and disclosure order against a third party bank and has conducted substantial cross-border litigation, as well as international joint venture claims and minority shareholder disputes. He continues to advise and act in cases involving jurisdiction and applicable law issues as well as cross-border enforcement of judgments. He has acted for creditors, secured and general, liquidators and troubled companies in the field of insolvency. He has maintained membership of the International Insolvency Institute for some years and was involved in the comprehensive and radical reform of Gibraltar’s Insolvency laws.

Also he secured for the Times Newspapers Limited the early dismissal of a libel action at the end of a lengthy litigation campaign. He has also built a substantial financial services compliance and regulatory practice, dealing also with data protection issues. He is the partner for over 12 years handling the firm’s pro bono representation of Gibraltar’s principal environmental NGO, regularly advising and taking a public role on high-profile issues. His criminal practice is mainly, but not solely, white-collar crime.
