Parole has been denied for both men who set a fire that killed three Seton Hall University students.
Monday's ruling means that Joseph LePore and Sean will be eligible to ask for parole again in 18 months.
LePore and Ryan admitted setting a banner on fire in a dormitory lounge in January 2000. Smoke spread throughout the six-story building.
Three freshmen died and dozens of other students were injured, some of them seriously burned.
The fire led New Jersey to enact the nation's first law requiring sprinklers in college dorms and boarding schools.
