    • Construction Law - 2021

      • "ALTANA has earned our top honor in Construction Law in France," says Best Lawyers President Phil Greer. "We congratulate the firm for their distinguished success in this field is over the past year." In addition to the firm winning this prestigious recognition, Partners François Muller and Christophe Lapp were recognized individually as well in the 2018 Edition of The Best Lawyers in France for their work in this field.

        When asked about the firm's work in Construction Law, François Muller added: "The biggest challenge here is to master the complexity and sophistication of the French construction law. Among others, we have a dual regime between public construction law and private construction law, which may be subtly different, and that’s not even speaking about public procurement rules, which of course are specific to the former."
