From the article it seems like the judge has said that the right to freedom includes the ability to travel out of the country or across country. It's just not reasonable to require some segment of the population (500-20,000 people) to take a boat to go to Europe, with no trial or ability to appeal. Movement is restricted.

It doesn't seem like a right on it's own, so much as included in the existing right to "liberty". My 2 cents.
