On January 28, 2015 the High Court ruled that the detention of asylum seekers at sea in what is known as the "contiguous zone" is authorised by the Maritime Powers Act 2013. 157 passengers were on board an Indian flagged vessel. One of them claimed false imprisonment. The High Court rejected this. The vessel had been intercepted by an Australian border protection ship in the Indian Ocean within Australia's contiguous zone. The vessel was detained, and once it became unseaworthy the passengers were transferred to the Australian vessel.
