Overview

  • On May 28, 2025, the Higher Regional Court in Hamm ruled that Lliuya’s case against RWE is inadmissible, ending a ten-year legal battle.
  • Judges concluded that available evidence failed to prove a legal link between RWE’s approximate 0.4% contribution to global greenhouse gas emissions and a specific flood threat at Lliuya’s Huaraz property.
  • The verdict is final with no avenue for appeal under German law, bringing closure to a landmark climate lawsuit.
  • Lliuya had sought a proportional share of about €17,000 toward a $3.5 million flood defence project to protect his Andean community from a glacial lake outburst.
  • Supporters, including environmental NGO Germanwatch, say the court’s reasoning establishes principles that could inform some 40 ongoing climate liability cases worldwide.
