In an exclusive interview with The Times of Israel, Julie Bishop suggested that, contrary to conventional diplomatic wisdom, the settlements may not be illegal under international law. She refrained from condemning Israeli initiatives to build additional housing units beyond the Green Line or from calling on Israel to freeze such plans, merely saying the fact that settlements were being expanded showed the need for the sides to quickly reach a peace agreement.
“I don’t want to prejudge the fundamental issues in the peace negotiations,” Bishop said. “The issue of settlements is absolutely and utterly fundamental to the negotiations that are under way and I think it’s appropriate that we give those negotiations every chance of succeeding.”
Asked whether she agrees or disagrees with the near-universal view that Israeli settlements anywhere beyond the 1967 lines are illegal under international law, she replied: “I would like to see which international law has declared them illegal.”
The position that settlements breach international law — adopted by the United Nations Security Council, the European Union and many other states and international bodies, but rejected by Israel — is based on an interpretation of the Fourth Geneva Convention. Article 49, paragraph 6, states that an occupying power “shall not deport or transfer parts of its own civilian population into the territory it occupies.” Violations of the convention are considered war crimes under international law. Israel is a party to the convention and therefore bound by it.
