How and where you do this may vary depending on which authority made the decision and whether you are lodging an appeal or requesting a reconsideration.
To request reconsideration, contact the authority which made the decision and ask it to reconsider your case. Your request should include information about how you believe the decision should be amended and the circumstances on which the requested amendment is based.
If the authority comes to the conclusion that its decision is manifestly incorrect as a result of new circumstances or for some other reason, it must change its decision in accordance with the applicants´ wishes. The reconsideration procedure must be fast and simple.
Reconsideration may not normally result in a decision that is more unfavourable to the applicant than the original decision. In principle, any number of requests for reconsideration may be made and the procedure is not subject to any limitation rules.
An authority is responsible for reconsidering a decision of its own accord if it finds the decision manifestly incorrect. Even when an authority reconsiders a decision of its own accord, this may not normally result in a decision that is more unfavourable to the applicant than the original decision.
In most cases, you can appeal against an authority's decision to a higher authority. This is usually a court, but may also be another authority.
Normally the appeal must be lodged within three weeks of the date on which you were informed of the decision. The appeal must be made in writing and must indicate the decision against which you are appealing and the requested amendment. The appeal should be addressed to the authority or court that will consider the case, but sent to the authority that made the decision. This is to give the original deciding authority a chance to reconsider its decision before forwarding the appeal to the relevant authority or court.
If the original deciding authority changes its decision after reconsidering the case, the appeal will not go ahead.
