Sarah has represented clients in leading competition damages claims in the English courts. She advises on both strategic and legal issues associated with litigation, such as choice of forum and reputational issues.

Sarah represents Microsoft in its cartel damages claims against Sony, Panasonic, LG Chem, Sanyo and Samsung in the High Court.  Sarah has also acted as a strategic adviser to a major global technology company with a number of competition damages claims and potential claims.

Sarah also assists businesses that find themselves under investigation by Competition Regulators and businesses that are concerned about the way their affairs may have been conducted - attending Dawn Raids, advising on defence strategies, assisting with responses to information requests, applying for leniency from fines (where appropriate), assessing potential civil liabilities, and making submissions.

Sarah regularly undertakes competition law audits, and provides training and compliance materials tailored to the particular needs of businesses, including how to deal with dawn raids.  She also advises on the competition law aspects of transactions and commercial agreements, including ways to structure agreements and alter commercial behaviour in order to minimise competition law risks. Her advice regularly considers the interplay between competition law and other legal standards, particularly intellectual property rights.
