A DPP spokeswoman declined to comment.
The inquest heard yesterday Monis had "delusional" ideas he was being watched constantly, even in his bathroom, leading a psychiatrist to diagnose him as suffering chronic schizophrenia.
Dr Kristen Barrett told the inquest Monis was referred to her in May 2010 after being hospitalised the previous month with dizziness and weakness attributed to mental rather than physical causes.
Monis had "delusional" ideas that he was being constantly watched by Iranian and Australian government security agencies, Dr Barrett said.
Monis was fearful of using his Medicare card because he suspected surveillance and asked if his consultation with Dr Barrett was being recorded.
"My impression was that he had chronic schizophrenia and my treatment plan was to start anti-psychotic medication," Dr Barrett told the court.
In September 2010, she prescribed an additional medication for anxiety after noticing symptoms of anxiety and depression in Monis.
Dr Barrett told the court Monis subsequently stopped his doses of both drugs by early 2011.
The hearing continues.
