The District Court in Poznań ruled that the decision by Polish energy company Enea SA to participate in the construction of a power plant in north-eastern Poland was legally invalid.

The lawsuit was brought by one of the company’s shareholders, environmental group ClientEarth, who argued that the construction of the country’s last coal-fired power plant would harm the company’s economic interests and pose an “indefensible” financial risk to investors in the face of rising carbon and falling renewables prices.
