Regarding the swiping of the tenat’s deposit the article reads:-
“But in almost a third of cases, the ADR found that the landlord had no grounds to request the clawback proposed  these landlords were basically trying their luck. So 29.35 per cent of all cases that went through the ADR were awarded 100 per cent to the tenant. Just 15.74 per cent of all cases were awarded 100 per cent to the landlord”.
