Check out http://austlii.community/wiki/DataLex. In Australia we are fortunate enough to have AustLII publishing virtually all Australian laws and court decisions (at least from this century) for free in a somewhat consistent HTML format. DataLex is the name for the “computational law” research AustLII staff have been doing since the 1980s. It’s interesting, but the real value of AustLII’s work is in getting the courts and legislatures to allow them to collect all the raw data and publish it in a free database with full text search. Just getting to that point is a huge improvement over what’s freely available in the US and the UK.
