For a legal practice involved in many of the most celebrated cases in Luxembourg – including arguably the most newsworthy case – the firm of Penning Schiltz Wurth (PSW) has retained a determinedly unstuffy atmosphere. Given that its client list ranges from private individuals all the way up to the state itself, via companies and organisations small and mighty, it is something that clearly works. “We’d like to think that we’re very accessible, and that we can interact better with our clients and they with us without the rigid formality so often associated with the law,” says Pierrot Schiltz, one of three founding partners.
