Poland breached European Union law when extending the life of its Turow lignite mine without assessing the environmental impact, an adviser to Europe's top court said on Thursday, siding with a challenge brought by the Czech government.
The adviser's opinion came as leaders of the two EU neighbours were set to meet amid reports they could sign a deal to resolve the long-running dispute over Poland's extension of mining at Turow, which produces lignite, or brown coal.
