There are four grounds to the appeal to the Full Court of the Supreme Court.

Tenants' Union of Tasmania solicitor Ben Bartl said he was disappointed by the appeal.

"We are very concerned that rather than focusing on tenancy best practice, including providing its tenants with reasons and a right of review before their eviction, Housing Tasmania is instead fighting a costly legal battle,” Mr Bartl said.

“Housing Tasmania should be using its limited resources to keep its tenants in housing not arguing for easier ways to evict them".  

Mr Bartl had hailed the court’s decision in December 2018 which effectively meant that all public housing tenants would have to be provided with reasons for their eviction and an opportunity to remedy any breach.

The case involved Gregory Parsons, of Glenorchy, who was handed a notice to vacate his home of 10 years in 2017 without warning, reason, or having breached any Housing Tasmania policies.

Housing Tasmania had extended his lease 13 times, for three and 12-month periods, over 10 years but then informed him his lease would not be extended.

When he did not leave his unit, Housing Tasmania sought an order from the Magistrates Court which was granted and then subjected to an appeal.

In the Supreme Court in December, Justice Gregory Geason said the original court decision had resulted in a denial of natural justice because Mr Parsons was given an order to leave his home without the opportunity to have his case considered as he was entitled to under the Residential Tenancy Act.

"This is not a case where the discretion was exercised incorrectly; it was not exercised at all," he said.

"The long history of repeated renewals enlivens enquiry as to the reason for service of the notice and ... about whether the reason for the notice is genuine and just.”

When the decision was handed down Mr Bartl said 15 Housing Tasmania tenants had been evicted over the past financial year without being provided reasons for the action or the right of a review.

"This is a significant victory for more than 7000 public housing properties across Tasmania," he said.

Mr Bartl said the practice had resulted in Tasmanians being forced into homelessness over many years.

The appeal to the Full Court of the Supreme Court is likely to be heard in March.
