I found it strange that one of the stated reasons behind the verdict was that the court believed that Nature and Youth's alternate proposal [1] of storing the waste in underground depots would not be any more environmentally friendly than the alternative [2]:
> "Viktigst er likevel at tingretten ikke finner mest sannsynlig at et driftsalternativ med lagring av avgangsmasser i dedikerte bergrom vil være miljømessig vesentlig bedre enn sjødeponi – alle miljøvirkninger tatt i betraktning." ("The most important fact is that the court does not find it likely that mining operations with storage of mining waste in dedicated subterranean depots would be a substantial improvement environmentally on storing it at sea - with all environmental consequences factored in.")
