A Rotorua principal says parents need to accept the consequences of their children's bad behaviour.
John Paul College principal and former New Zealand Secondary Principals' Association president Patrick Walsh said it was difficult for schools to uphold standards when parents undermined their authority.
Parents of students of St Bede's College in Christchurch hired a lawyer to apply for an injunction after two boys were suspended from its Maadi Cup team after they rode a baggage carousel into a restricted part of Auckland Airport.
Last year, a St John's College student who was suspended for refusing to cut his hair, was awarded $24,000 in costs.
"It seems to me on the St Bede and St John case, and there's been others, that unfortunately parents don't accept the natural consequences of their children's behaviour.
