The Norfolk Island Legislative Assembly decided to hold a referendum on the proposal. On 8 May 2015, voters were asked if Norfolk Islanders should freely determine their political status and their economic, social and cultural development, and to "be consulted at referendum or plebiscite on the future model of governance for Norfolk Island before such changes are acted upon by the Australian parliament". 68% out of 912 voters voted in favour. The Norfolk Island Chief Minister, Lisle Snell, said that "the referendum results blow a hole in Canberra's assertion that the reforms introduced before the Australian Parliament that propose abolishing the Legislative Assembly and Norfolk Island Parliament were overwhelmingly supported by the people of Norfolk Island".
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): When did the Legislative Assembly of Norfolk Island vote regarding the proposed Australian reforms?
