Convicted murderer Daniel Houma has had his minimum non-parole period reduced by a year in a judgement from the Court of Appeal.
Houma had been convicted of kicking and beating to death father of three Thomas Martin in an unprovoked attack in Glen Innes in April 2006.
He was also convicted of seriously assaulting of a security guard on the same night, whose injuries meant he was off work for was nine months.
Houma was jailed for life with a 16 year non-parole period for murder and received a concurrent 6 year sentence for the assault.
The Court of Appeal cut the non-parole period from 16 years to 15 years, mainly due to issues of disparity with shorter sentences given to Houma's two co-accused.
