In 2007 Gregory Ferguson, a Marist priest, was sentenced to two years jail (eligible for parole after 12 months) for offences in 1971 against two boys aged 13 at Marist College, Burnie, Tasmania. On 13 December 2007 he was sentenced to an additional three years' jail for offences against a third boy. While in 2008, a jury found former priest Roger Michael Bellemore guilty on three counts of maintaining a sexual relationship with a young person under the age of 17 years in the 1960s and 1970s, while he was at the same College. In 2015, Archbishop Julian Porteous was notified that a complaint had been filed with the office of Tasmania's Anti-discrimination Commissioner in relation to the distribution in all Tasmanian Catholic schools of a booklet, "Don't Mess with Marriage", stating marriage should be a "heterosexual union between a man and a woman" and changing the law would endanger a child's upbringing. The complaint was filed by a transgender activist and Federal Greens candidate Martine Delaney. The complaint was called "'an attempt to silence' the Church over same-sex marriage" by Archbishop Porteous. The complaint was treated as a possible breach of the "Anti-Discrimination Act 1998" (Tas), and sparked fierce debate on the issues of freedom of religion, freedom of expression, and tolerance.
