Mass claims
De Gier | Conflict Solutions specializes in consulting around mass tort situations. Involvement ranges from counseling aggrieved parties on novel issues, to being a board member of advocacy organizations, project management, business mediation and being lead counsel on the advocacy team.
Adriaan de Gier is chairman of the board of interest group Stichting CZFL and operations director of interest group Stichting ICAM. He is an internationally recognized expert, speaker at domestic and foreign mass tort conferences, member of the international organization Class Representatives World Network and member of the Dutch interdisciplinary roundtable mass tort.
In large cases, Adriaan de Gier leads project teams with experts from various law firms and other disciplines who handle the case under his responsibility.
Assessment of whether a situation lends itself to a mass tort approach is non-binding. If so, the case will be built up and prepared for further action.
“Extraordinary how tenacious Adriaan de Gier is, how he can hold a case he’s cut his teeth on for as long as it takes. Mass tort situations can take an enormously long time, so that is an indispensable trait. And with success: in the Fortis case, we were the only ones to get a winning verdict after six years, and that, by the way, was the starting shot for the negotiations with Fortis/Ageas, which resulted in 1.3 billion in investor compensation.”
