It might not look much but Australia has just thrown a huge spanner in the works of international internet retailers who want to operate in their market. Whether it sets a precedent remains to be seen but, if so, cheap goods sent from overseas might have to be a lot less cheap. At the heart of this is unproven conduct by Wiggle Limited, a UK company, which the Australian Consumer and Competition Commission (ACCC) found to be in breach of Australian law. This is a significant extra-territorial application of domestic law - and it also interferes with the right to include a choice of law and choice of jurisdiction clauses in international contracts. And as if that's not enough, the ripples reach into call-centre operations worldwide.
