The State of Tasmania is challenging the World Heritage Properties Conservation Act 1983 federal law which is used by the federal government to prevent the government of Tasmania to build a dam on the Franklin River. Indeed, the law was passed in order to allow the federal government to prevent damages that could be done to World Heritage sites such as the Franklin River.The State of Tasmania, who supported the construction of the dam, challenged the World Heritage Properties Conservation Act, 1983 in front of the High Court of Australia on the basis that the federal government was exceeding its power by passing a law which would extend its power to World Heritage sites.The judges of the High Court considered that the law was in line with the constitution because it was authorised under the "external affairs" power of the federal government.
