The boy admitted he lit his socks on fire, which he said he had done several times before without incident, and when he stomped his foot to extinguish the flame it ignited a carpet soaked with gasoline from an earlier spill.
The boy and his friends attempted to extinguish the fire, but the garage burned down, police said.
"(He) was 14 years old, and although his intelligence appeared to the (Youth Court) judge to be average, average 14-year-old boys may do things without any thought of the risks involved, even when they have been told about the risks on other occasions," Justice Jill Mallon said in the High Court ruling.
