A street preacher who went to jail in 2009 for the frenzied stabbing of a man in Canberra has had an appeal against his sentence dismissed.
Isa Islam, 40, was well known around Canberra for his religious preaching.
On July 4, 2009, he was street preaching when he tried to talk to a former neighbour who he blamed for breaking into his home.
When the man tried to walk away, Islam pulled out his small lunch knife and repeatedly stabbed the other man before smashing his head against the ground.
The first police to arrive at the scene found Islam standing quietly with his hands covered in blood and saying "I did it, I'm the one".
The victim was left a quadriplegic.
Islam was sentenced to nine years in jail but he appealed on the grounds that the judge did not properly consider his mental illness.
On Thursday in the ACT Supreme Court, Justice Richard Refshauge dismissed Islam's appeal.
Justice Refshauge also dismissed the Crown's cross-appeal to have Islam sentenced to more time in jail.
Islam will still be eligible for parole in 10 months.
