Clifford Chance has hired a 14-lawyer team (pictured) from White & Case led by prominent partner Alexandra Diehl, in one of the largest team moves in the German market in recent years.
The team will be based out of the firm’s Frankfurt office, and includes two W&C local partners: Priscilla Tatschner and Lisa Becker. Tatschner will join as a local partner, while Becker will join as a counsel.
The move comes amid what CC’s Michael Kremer, head of litigation and dispute resolution in Germany, describes as a ‘hugely growing market’ for collective redress and class actions across Europe, a development that he says has evolved far beyond the 2015 Dieselgate scandal, when Volkswagen was found to have installed software that manipulated emissions tests in its diesel cars, triggering global outrage, billions in fines and a flood of follow-on claims against other manufacturers accused of similar practices.
‘Initially everybody thought Dieselgate might be a one-off and nothing like that would come again,’ Kremer told Legal Business. ‘But now you see different types of data-privacy-related mass litigation, a lot of consumer protection claims, and product-liability actions, especially in pharma, financial services and insurance.’
Diehl, who was previously a senior associate at CC for eight years before moving to W&C in 2018, has experience advising on collective redress and mass tort claims in a range of industries, in particular in regulated sectors such as healthcare, life sciences, automotive and technology.
Clifford Chance said in a statement that the team will add to the firm’s expertise in these regulated industries.
Matthew Newick, the firm’s global head of litigation and dispute resolution, called the arrival ‘an important development for our global disputes practice, positioning us to deliver seamless, high-quality advice across jurisdictions.’
Stefan Sax, managing partner for Germany, added that the country is ‘rapidly becoming Europe’s epicentre for collective redress,’ describing the team move as one that ‘deepens our bench and enhances our ability to support clients facing high-stakes, cross-border disputes.’
The team will bring across several mass litigation matters, including the ongoing product liability mass claim for BioNTech relating to its Covid-19 vaccine, Comirnaty.
Diehl also has particular expertise in arbitration, where she is recognised by the Legal 500 as a next generation partner. Her hire complements CC’s established international arbitration strength in Germany, notably the ISDS (investor-state dispute settlement) practice led by Moritz Keller, former head of Freshfields’ Vienna arbitration practice.
‘Alexandra has arbitration experience that can strengthen collaboration with our exemplary arbitration team,’ Kremer said. ‘We can quickly mix teams and avoid silos, using our mass-litigation expertise alongside arbitration capability to offer clients a broader disputes solution.’
He added that Diehl’s group is bringing technical and AI-driven case-management tools, enhancing the efficiency of handling large-scale claims.
The Frankfurt expansion reflects CC’s ongoing investment in high-growth disputes areas, including collective redress, arbitration, restructuring and patent litigation. In recent years, the firm has made notable hires across Europe, the US and Asia, including Brad Woodhouse, who joined the firm’s Sydney office from national firm Corrs Chambers Westgarth as head of class actions for Australia this July.
‘We continue to invest where our clients need us to be and where we see potential for sustainable growth,’ said Kremer. ‘Mass litigation and arbitration are natural interface areas that allow us to leverage the firm’s platform globally.’
For Diehl, the move marks a return to familiar territory. ‘It’s a great pleasure to be returning to Clifford Chance,’ she said in a statement. ‘The collaborative culture and global platform provide the ideal environment to create advantage for our clients.’
Kremer concluded: ‘Mass litigation is here to stay, and we have the right team and platform to lead in that space.’
White & Case declined to comment.

Pinsent Masons saw revenue rise by 4.7% to a new record high of £680m over the year, a result senior partner Andrew Masraf (pictured) described as cause for celebration – while also acknowledging the scope for improvement.
National firm Blake Morgan, which has six offices across the UK, boosted PEP by 8% to £349,000 in 2024-25, against a 4.6% increase in revenue; however managing partner Mike Wilson (pictured) said PEP could have been higher still, but for the firm’s strategy of investing profit back into the business.
At Hogan Lovells, which put in one of the strongest performances of the international firms, with PEP up 9.1% to £2.4m, global corporate and finance head James Doyle (pictured) stressed the importance of adaptability in a fast-changing marketplace.

Response rates for London referees saw a double-digit increase this year, with rising by almost 12% to a new record high of more than 31,000.
