Norway's supreme court dismissed a lawsuit by campaigners who claimed that Arctic oil exploration violated people's right to a healthy environment, Norwegian media reported on Tuesday.
The country's supreme court approved the government's plans for Arctic oil exploration.
Greenpeace and the Nature and Youth group claimed the 2015-2016 oil licensing round, which awarded Equinor and other participating companies, breached Norway's constitution.
In 2016, Nature and Youth and Greenpeace sued the state of Norway. They claimed the authorities violated the Constitution's environmental protection rules.
In the same year, Norway provided 10 new licenses for oil and gas detection in the Arctic.
The main investment was in the south eastern region in the Barts Sea, an area opened in 2013 for petroleum activities.
Other permits were granted in the south of the Barents Sea, where oil activities have taken place since the 1970s.
