How can I appeal against decisions on fi-domain names?

If a domain name is found to infringe a protected name or trademark owned by another party, Traficom removes the domain name from the register and transfers it to the claiming party, if so requested. You can appeal the decision to the Market Court.

The owner of the infringed name or trademark can request the fi-domain name to be removed from the domain name register and transferred to them. The decision is usually sent by email to the parties involved. The decision is deemed to have been received on the third day from sending the email. If you are not satisfied with the decision you can appeal the decision to the Market Court. (External link) 

You must make the appeal in writing within 30 days of receiving the decision. The date of notice is not included in the appeal period. Each decision comes with detailed instructions on how and when you can appeal the decision.
