Well now we have the other side of the story. Ex live-ex veterinarian Dr Lynn Simpson has confirmed that "rejects" were not always rejected at port. She details the frustrations and difficulties that the "rejects" caused shipboard veterinarians, knowing that these animals should never have made it onto the boat.
This isnt an overseas issue. These non-rejected "rejects" were animals that should have had protection under Australian law ie ASEL.
