legislation: 6 questions
law: 14 questions
Or is there a subtle difference I don't get?
law is used for questions if something is legal or not.
legislation is used for questions about the law-making process itself.
Update: In addition, now there's also legality.
Thinking about it a little more, I guess one common tag should be enough.
If there are no objections, I'll go ahead and merge the three tags into legal for now. If desired, we can always rename the tag later.
On a related note: If the proposed Law SE makes it into public beta and survives the initial phase, we should think about if we want to outsource our "Is it legal to … ?" questions there, since I have a strong feeling that we don't have too many lawyers or law experts here on Open Data SE. Anyhow, let's cross that bridge when we come to it.
