I'm only guessing here, but I don't think the lawyers could legally insist people returned the records that had already been sold (also, it would be practically impossible to do this - could you imagine them saying "okay, who's got the remaining 323 out there?") Also, I think the copyright infringement only covers public broadcasting of the records - in the same way that anyone can put together a compilation/remix/bootleg and listen to it on their own - they're only breaking copyright law if they play it to someone else and/or they try to sell it on. I think there is also a gap - as someone pointed out - whereby if you really do give the item away for free, that's allowed. It's a really messy area of the law and I guess theoretically that offering effectively banned records for sale (even second-hand ones via an auction) is probably contravening one of the subclauses in the Copyright Act. However, I don't think any lawyer would find it worth their while to take legal action against a person - at the end of the day there would be massive legal costs and you could simply turn round and say "oh, sorry - I didn't know it was banned" and give it them back. Okay, you'd be 60-90 quid down but they'd have costs in the hundreds... I have a friend who deals with music royalties - I'll ask her next time I see her.
