Many are the instances of business people not liking what scientists say. And if there’s money involved, when people don’t like what’s being said, they sometimes try to keep scientists from saying it.
In this case, the issue is a proposed ban on deep-sea trawling:
Lobbying groups have threatened legal action against scientists for publishing data deemed to be critical of the industry. The EU Fisheries Committee includes Members of the European Parliament from French, UK and Spanish areas in which deep-sea fishing vessels are docked. These ties have slowed the committee’s consideration of the proposed ban to a crawl.
