Nerendra Jeet Singh, a Sikh, went to court in New South Wales (NSW), Australia over a bicycle helmet fine. He escaped the fine, arguing that his identity and religion are of prime importance.
Sikhs have helmet exemptions in South Australia, Western Australia, Queensland and Victoria.
In Victoria, Alan Todd challenged a helmet fine in court, avoiding the fine.
People who challenge a helmet fine in court often escape it. In NSW, the defence of necessity allows people to break a law to avoid more dire consequences. Bicycle helmets increase the risk of accident and injury. To avoid these dire consequences, cyclists can ignore the helmet law.
This might explain why the police rarely book cyclists for helmets in NSW. It is pointless harassment: most people give up cycling, those who prefer to keep riding can challenge the fine in court.
