An Auckland secondary school has lost an appeal against a ground-breaking ruling on how schools should deal with student suspensions.
Lynfield College appealed against a High Court decision last year forcing it to take back an expelled student.
In that decision, the court ruled the school's board overlooked some legal requirements when it twice suspended and ultimately expelled a 16-year-old for alleged incidents of truancy drug use and misbehaviour.
In its appeal, Lynfield College argued that the judgment had swung too far in favour of the student.
But the Court of Appeal said it agreed with the result reached by the High Court.
Principals have argued that the High Court ruling has made it more difficult to deal with seriously misbehaving students.
