A court ruling in Płock has overturned an environmental decision made by the president of Ciechanów regarding a residential housing project on the Krubin wetlands. The project, proposed by the Social Housing Initiative North Mazovia (SIM), involved the construction of ten apartment blocks on Miła Street.

The Local Government Appeal Office (SKO) determined that the initial decision was marked by “discretion and arbitrariness.” The office found that the investor’s application lacked necessary documentation and failed to satisfy environmental law requirements. Additionally, inspectors noted that the scale of the development would likely cause environmental impacts extending to neighboring properties.
