There are a few people blogging out there on the Lisbon Treaty and the referendum, but there is - to my knowledge - only one person going through it forensically - Ralf Grahn, a Finnish lawyer. While I wouldn’t be in accord with all of his views, his work on this is first rate and anyone taking an interest in the Treaty should definitely take a look. The consolidated version of the Treaties (i.e. what we are voting on) is available from the Institute of European Affairs.
