Although Points A12 and A25 are almost equidistant from Australian and Indonesian territories and Points A16 and A17 are almost equidistant from Indonesian and Portuguese territories as they existed in 1972, the lines joining the turning points are not equidistant lines. The debate in respect of these lines concerned seabed topography and thus equidistance would only have been an appropriate method of producing an equitable settlement if Indonesia’s claims had prevailed. When they did not dominate it was inevitable that the line would traverse the disputed zone between the line of equidistance and the axis of the Timor Trough.
