It ordered the state to annul the verdicts and pay the claimants approximately USD150,000 each in compensation, and demanded that Chilean courts in the future should be more rigorous in their use of anonymous witnesses in anti-terrorism cases.

Emmerson, a British lawyer, was investigating the Mapuche conflict and visited Araucanía and Biobío, the two southern Chilean regions at the heart of the conflict.
