An appeals Court in Sweden has ruled that a Poker tournament is primarily a contest of skill and thus not gambling under Swedish law. http://www.pokerpages.com/poker-news/news/sweden-reduces-illegal-poker-tourney-sentences--rules-tourney-uses-skill-31665.htm
Unfortunately, the Court did not see that the same principle should apply to cash game poker, and upheld gambling charges for those. The rationale appears to be that you are guaranteed to play many hands in a tournament, but you may play very few hands at a cash game. Obviously they accept the "skill manifests over time" principle.
Personally, I think they missed the point regarding cash games as skill can manifest in those just as easy as in a tournament. But when you have thousands of players going around saying "luck in the short run, skill in the long run" this is the result you get.
Still, legal tournament poker is better than no poker at all!
