There would be a vast difference between being charged with using an illegal seat and being sued for negligence. IMHO, I Think any court would have a hard time finding negligence when there are so many studies etc proving otherwise.... youvwould simply go to court and they would have to prove that the child would be safer in an Australian seat.... which I think would be near impossible.... legal eagles please correct me if I'm wrong
That's what I think too Caz. Negligence would have to be proven first, ie: that the seat you used was less safe than an Australian approved seat. I'm not sure how it works legally as to which party has to provide the testing I would imagine the suing party? Again any legal eagles out there that would know the answer to that? It's just all food for thought for anyone thinking of importing. I'm not a trained safety expert, but, I would highly doubt a correctly fitted and used European seat, that has also passed the Swedish plush test wouldn't beat an Aussie approved seat safety wise!

Addit: I would so LOVE to see that crash test!!!!! I imagine Aussie experts would have swallow their egos and admit we don't have the safest CRS in the world any more
