The Kingfish Company N.V. announced that an appeal of the Maine project has been rejected and the project's state permits have been upheld. This is the second appeal which has been rejected at the state level. Kingfish Maine remains a fully permitted project as Maine's Superior Court has denied the latest appeal by the project's opposition, the Roque Island Gardner Homestead Corporation and Eastern Maine Conservation Initiative.

The Maine Superior Court has upheld the Maine Board of Environmental Protection's affirmation of Kingfish Maine's Site Location of Development Act (SLODA) and Natural Resources Protection Act (NRPA) joint permit. The SLODA/NRPA permit was issued by the Maine Department of Environmental Protection in 2021 and affirmed, on appeal, by the Maine Board of Environmental Protection (BEP) in 2022. This was Roque Island's second appeal denial, on the state level, in their continued attempt to stop the project.
