Drawing upon procedural skills utilising conventional litigation and ADR techniques as well as significant substantive subject matter knowledge, including in the finance and funds sectors, KLEYR GRASSO is ‘particularly impressive in the area of commercial litigation’, from both a domestic and cross-border context. ’A strategic and solid advocate’, Marc Kleyr remains very active and can call upon a vast reservoir of institutional knowledge in the field, regularly acting on shareholders disputes, as well as having niche expertise in relation to professional negligence actions, particularly in relation to claims against auditors. Fairly atypically among many of the leading business law firms highlighted in the ranking, the team also has significant exposure to criminal law mandates, with Rosario Grasso very adept at handling a range of white-collar work, including as it relates to allegations of money laundering. The ‘assured and competent’ Donata Grasso is recognised for her skill at handling arbitration, complex debt recovery and enforcement proceedings, as well as a range of general commercial disputes. She rounds out the team at a leadership level alongside the ’very responsive’ Emilie Waty, who has developed a particularly strong reputation on the arbitration front.
