No, it's just a problem with the link (probably my fault). I don't seem now to be able to link to the article itself, but here's another link to the barrister writing about the case, which includes a link to the article itself.

Hebden v Domino

The case has been widely reported in both the legal and general press, so if that doesn't work try googling Hebden v Domino Recording.

I'm not a lawyer and I don't know to what extent this might be a precedent for Dick's case, but it does seem to suggest that a record company could be under an implied obligation to publish the recordings it holds the rights to.
