Centre for Environmental Justice, Withanage Don Hemantha Ranjith Sisira Kumara, Pathragoda Kankanamge Dilena, Rev.Fr. Santhiyogu Marcus (President, Citizen' Committee Mannar) and Noor Mohamed Mohamed Aalam (Secretary, Mannar District Fishermen Co-Co-operative Societies' Union) filed a Fundamental Right case, case bearing number SCFR 152/2024 on 05th of June 2024. Cabinet of Ministers of Sri Lanka has purportedly decided to award the construction and operation of the Mannar Wind Power Project (Phase II) to Adani Green Energy Sri Lanka Limited (AGESL) as a Build, Own, and Operate project for 25 years.

The Environmental Impact Assessment (EIA) for the proposed 250 MW Mannar Wind Power Project Phase II reveals significant environmental damage caused by existing wind farms along the south coast of Mannar, particularly affecting migratory birds more than initially predicted. The EIA reveals higher bird collision risks in the Thambapawani Wind Power Project, urging reconsideration of future projects in Mannar, a crucial area for biodiversity and migratory birds.

The project site lies in the center, encircled by three Protected Areas (PAs). These are the Adam’s Bridge Marine National Park, the Vidataltivu Nature Reserve, and the Vankalai Sanctuary (a RAMSAR site), which are protected sites that fall under the purview of the Department of Wildlife & Conservation (DWC), and all these parks are of vital importance to the biodiversity of the country. The Mannar Wind Power Project Phase II, involving 16 wind turbines, affects communities across several Grama Niladhari Divisions, including 151 homes. However, it does not adequately address its impact on local socio-economic activities, particularly fishing. The project's 25-foot depth could mix groundwater with salty water, potentially causing water quality issues and severe pollution of drinking water wells.

The petitioners seek to declare that their fundamental rights, as well as those of the people/public of Sri Lanka, have been infringed by the respondents, including their servants, agents, and nominees, through executive and/or administrative action.This also includes an imminent violation of the petitioners' fundamental rights to equality and/or equal protection of the law, as guaranteed by Article 12(1) of the Constitution. 

On the 18th of March 2025, the case was called for leave to proceed, and the Attorney General’s Department informed the court that Adani Company had officially notified the Board of Investment (BoI) of its decision to withdraw from the project. Following this development, petitioners requested permission to withdraw their applications.
