A mentally-ill tenant who set fire to his home in Mawson was on Friday found not criminally responsible for the arson.
Arnont Singsathitsuk, 21, was arrested in January last year after lighting on fire his bathroom, a bin of leaves and an electrical appliance.
He also damaged property before fleeing from the home.
Singsathitsuk pleaded not guilty by reason of mental impairment to a charge of arson and two counts of damaging property.
Prosecutors agreed to the pleas and the verdicts were entered by the court at a hearing on Friday in the ACT Supreme Court.
Two forensic psychiatry experts told the court Singsathitsuk was suffering from schizophrenia and cannabis use disorder at the time he set fire to the home.
The experts concluded Singsathitsuk was not aware his conduct was wrong.
One expert, Dr Richard Furst, said the man was "acutely psychotic, was elevated in his mood, [and] had grandiose delusions".
The delusions included he was the God of Neptune and he had to light a fire to make smoke and bring rain to Australia, which was at the time consumed by unprecedented drought and bushfires.
Dr Furst also said because the man had never been diagnosed with a mental illness he did not have the capacity to assess his behaviour and whether or not it was wrong.
"On the contrary, he had no malicious intent and clearly believed he was doing the right thing," Dr Furst said.
Justice Michael Elkaim ordered Singsathitsuk submit to the jurisdiction of the ACT Civil and Administrative Tribunal, where the man's case would be dealt with under mental health laws.
