Following a recent request from a colleague as to a good way of keeping up to date with the mass of legal changes, especially in the field of Intellectual Property, I recommend the IPKat blog as a good start, which can be found at:

The following sites post daily changes:

The live feed for the UK Supreme Court is at:
