The son of a woman killed in a horrific crash has declared the justice system "absolutely broken" after prosecutors lost their appeal of the driver's three-year prison term.
Christopher Joannidis ignored a police warning about the dangerous roads in Strathmerton, in Victoria's north, disregarded signs and crossed three sets of rumble strips before killing five people and a dog.
He had just been given a speeding ticket before he crashed into a ute, which was pushed into the path of a truck towing two trailers along the Murray Valley Highway in 2023.
