Can I appeal the Board’s decision if I am not happy with it?
There isn’t a set appeal process for an unsatisfied Board hearing result.
You can write to the Board if you have new information that would help your case, and ask for a rehearing. However, there is no specific law that requires the school to take you back or to have a rehearing.
If you think the process (not just the outcome) they followed in reaching their decision wasn’t fair, you could complain to the Ombudsman, but the process is extremely lengthy, and the Ombudsman can only give a recommendation. If you think you have been discriminated against under the Human Rights Act, you can contact the Human Rights Commission. The other option is to hire a private lawyer and to bring a case called a judicial review through the High Court, but this is an extremely expensive and lengthy process.
The other options are to lay a complaint with the Ministry of Education and/or the Education Review Office. However, they may not actively do anything to resolve your complaint unless there is an extremely clear breach of the process.
