This story did the rounds at the start of the year, and I see it getting quoted again now in comments in various news sites. Here is Daily Kos's quote of a press release:
“Whereas cetaceans in general are highly intelligent and sensitive, and various scientists who have researched dolphin behavior have suggested that the unusually high intelligence; as compared to other animals means that dolphins should be seen as ‘non-human persons’ and as such should have their own specific rights and is morally unacceptable to keep them captive for entertainment purpose,” the ministry said.
The story appears to be that captive dolphins in aquariums have been banned, but what exactly is the "non-human persons" aspect? Does it have any force in law?
