The couple stated that it was a one off replica, however there is irrefutable evidence that they had a company making replicas, and were advertising and marketing them for sale.
The impression I'm getting is if you're upfront, and work with JLR (and I imagine chuck them some wedge) then you can build a replica like the Eagle. Lie to them, of refuse to do it their way, and they'll see you in court.
I'm not aware of anyone "chucking JLR some wedge" in order to make replicas. The reason they don't go after Replica makers in the UK is because they'd lose. An Eagle isn't a replica BTW, it's an upgraded original.
The head of Jaguar Classic has released an open letter which has since been shown to contain many false statements. This is backed up by court documents that the couple have made public.
The couple were originally planning to make two further replicas for sale but dropped the plans after being contacted by JLR. JLR have stated that they didn't initially ask the couple to destroy their own car. The court documents have shown that to be another false statement.
Personally I hope the couple win the appeal and show Jaguar Classic up for what they are.
