A ground-breaking judgment of the Australian Federal Court regarding the Montara oil spill in the Timor Sea in 2009, Sanda v PTTEP Australasia (Ashmore Cartier) Pty Ltd (No 7) (Sanda (No 7)),1 is one of the few Australian class actions to proceed to a favourable judgment for the claimants. It is also the first judgment against an Australian company for cross-border pollution loss suffered by foreign claimants.
