“It was the statutory scheme that meant that [the purchaser] acquired the registration mark. That does not mean that there was no enrichment or no unjust enrichment. On the contrary, it is the reason why there may have been. His potential enrichment consisted in his acquisition of a car carrying with it a potentially valuable registration mark. Any such enrichment must have been at the expense of [the vendor]. … Further, it was legally unjust for [the purchaser] to keep the registration mark, since it was an express term of the auction contract that he would not receive the vehicle's existing mark (whatever that might be), but would instead get an age-related mark, and he only obtained the old, cherished mark as the result of a mistaken failure by Coys to operate the statutory scheme correctly on behalf of the estate, about which mistake [the purchaser] soon became aware.”
“The underlying issue is whether the car was sold with or without the cherished registration mark … Sir John contends that it was sold without the mark. Mr Harrison contends that it was sold with the mark and Sir John contends that, if that is right, [Coys] were in breach of their duty to him.”
“On the information provided by Coys no reasonable buyer could have come to the conclusion that the Mark was included in the sale.”
“In my judgment [Bullock or Sanderson orders] are appropriate nowadays only in those cases where the claimant does not know which party is at fault and it is inappropriate to make either order when both defendants succeeded in defending a large part of the claim. I consider also that it would be contrary to the objective of [CPR] r.44.3 to make a qualified Bullock or Sanderson order.”
“quite a difficult area to explore, as is apparent not only from the length of the passages in my judgment in which it is considered, but also from the efforts devoted to it in the skeleton arguments at trial.”
