Disputes
In order to increase public awareness about domain names and decisions adopted by Czech courts with respect to domain names, CZ.NIC Association publishes verdicts pertaining to suits in which CZ.NIC Association is involved, or about which the Association has been informed by courts or any of the parties concerned.
Procedure for Conducting a Dispute
Except for data which may serve as an identification of the parties concerned or any other entities and the domain names in question, the texts are modified as little as possible. Any relation between the abbreviations and dummy symbols used and the people or domain names using such abbreviations or dummy symbols for purposes of identification is merely accidental.
Court Decision Statistics – as of 11/2022
When studying this decision, it is necessary to be aware of the fact that the decision comprises not only of the verdict alone and the pertinent justification, but also of a summary of the claims presented by individual parties involved, and that the court may not have been concerned with some of these claims at all (e. g. with respect to the issue of interlocutory judgement) and that such claims represent merely a legal opinion of the party concerned, not a finding of the court. This decision may not be automatically applied to other instances even though they may be similar. CZ.NIC Association recommends consulting each particular case with experts in domain names and lawyers.
Resolution of disputes concerning domain names
Disputes between CZ.NIC and domain name holders
Pursuant to the provisions of Article 23 of the Rules of Domain Names Registration under ccTLD.CZ , disputes between CZ.NIC Association and domain name holders concerning domain names registered by holders may be settled before the Arbitration Court attached to the Czech Chamber of Commerce and the Czech Agrarian Chamber at the domain name holder's discretion.
Dispute settlement between domain name holders and third parties through arbitration
Domain names that were registered or had their validity extended before 1 March 2015 are governed by The Alternative Dispute Resolution Rules which contain provision for resolving disputes concerning the registration/use of domain name and the mechanism of a public arbitration offer. Domain name holders are obliged to express their informed consent with the current version of the Rules of Alternative Dispute Resolution.
The provisions of these Alternative Dispute Resolution Rules stipulate that if a third party believes that the registration/use of a specific domain name has affected its rights, said party may decide to settle the dispute either before a court of general jurisdiction , or the Arbitration Court attached to the Chamber of Commerce and Agricultural Chamber of the Czech Republic. If said third party decides to settle the matter before this Arbitration Court, the domain name holder is obliged to submit to this procedure in accordance with the public arbitration offer.
Please note, however, the decision of the Supreme Court of the Czech Republic under case No. 23 Cdo 3895/2011, which challenged the possibility of concluding an arbitration agreement in the described method, and with it the opinion to resolve domain name disputes through the Arbitration Court (in Czech only).
As of March 1, 2015, due to the launch of the new alternative dispute resolution system, it is no longer possible to resolve domain name disputes through arbitration proceedings before the Arbitration Court.
Dispute Settlement Between Domain Name Holders and Third Parties Through Alternative Dispute Resolution
From 1 March 2015, The Rules of Domain Name Registration under the .cz ccTLD include an entirely new document entitled Rules of Alternative Dispute Resolution. The system for resolving disputes following these Rules of Alternative Dispute Resolution does not represent arbitration proceedings as defined by law; the holder of a domain name undertakes to submit to it if the petitioner chooses this method of dispute resolution. Settlement of disputes in this case also utilises the platform managed by the Arbitration Court attached to the Czech Chamber of Commerce and the Czech Agrarian Chamber in accordance with the Code for the Resolution of .cz Domain Disputes .
This method of dispute resolution has a contractual basis; it is not an arbitration process within the meaning of Act 216/1994 Coll. on arbitration proceedings and arbitration rulings, and cannot be used to claim anything other than the termination of a domain name registration or its transfer. No additional claims are acceptable, in particular payment of the costs of the proceedings or compensation of damages. The issued decision does not represent a writ of execution; the settlement of disputes following the Rules of Alternative Dispute Resolution does not affect any other ongoing proceedings in the same matter and the conclusion of a dispute under this system is without prejudice to the res judicata rule. This means that in the course of the settlement proceedings or afterwards, it is possible to raise the same claims before a court of general jurisdiction. This system of dispute settlement is binding for those domain name holders who registered their domain name or extended its validity on 1 March 2015 or afterwards.
In order to settle the dispute, an independent expert proceeds in accordance with theCode for the Resolution of .cz Domain Disputes . The proceedings are conducted electronically, without the physical presence of the parties, on the online platform managed by the Arbitration Court and available at Code for the Resolution of .cz Domain Disputes . A dispute may be resolved by one arbitrator or a panel of three arbitrators appointed in accordance with the Code for the Resolution of .cz Domain Disputes; only a person included in the List of Arbitrators may act as an arbitrator. To communicate with the holder of the domain name in dispute, the e-mail address associated with the Contact in the central domain registry maintained by the CZ.NIC Association is primarily used.
Each party pays its own costs for out-of-court dispute settlement, which include in particular fees for resolving the dispute imposed by the Arbitration Court and other costs associated with the dispute, typically the costs of legal representation and other expenses. While it is not possible to award compensation of costs in this system of out-of-court settlement, the parties may raise this claim before courts of general jurisdiction.
Interpretation of the provisions of Article 18.1. of the ccTLD .cz domain name registration rules
The following interpretation of the Registration Rules is intended as a description of CZ.NIC's approach to handling domain name disputes. The interpretation is based primarily on the technical capabilities of the domain name registration system and is intended primarily as a basis for formulating a statement of claim, whether by the claimant or the court. The ways of handling domain names that are the subject of a dispute are not limited to those described below in this interpretation, and it is therefore not excluded that the claimant or the court may formulate the statement of claim differently.
However, in such a case, it may be technically very difficult to ensure the implementation of the decision.
Accepted decisions
The following decisions serve as the basis for carrying out actions related to a domain name:
a court of general jurisdiction
an arbitration court (proceedings commenced before 1 March 2015)
an ad-hoc appointed arbitrator
a professional decision of an expert (since 1 March 2015)
The decision shall be submitted to the CZ.NIC Association in the original or as an officially certified copy.
It must contain an attached clause that certifies its legal effect and enforceability (this does not apply to preliminary injunctions).
In the case of a decision by an ad hoc appointed arbitrator, the decision must be accompanied by documents proving that both parties to the dispute agreed to the resolution of the dispute by the ad-hoc appointed arbitrator (statement, arbitrator agreement or arbitration clause).
Identification
The decision must unambiguously identify the domain name concerned; otherwise, the requested actions cannot be performed. The decision must also unambiguously identify the holder of the domain name concerned.
It is not necessary for the CZ.NIC Association to be a party to the proceedings in which the decision was reached in order for the actions to be performed. The CZ.NIC Association shall therefore perform all the required actions even if the Association is not the defendant and the legal action was only taken against the domain name holder concerned.
If, according to the decision, the CZ.NIC Association is obliged to change the holder of the domain name, the person who is to become the new holder under the decision must, within three days of submitting the decision, also provide the identifier of the Contact for which the registration is to be carried out. In any other case, the CZ.NIC Association will generate a new Contact for the holder for which the registration will be performed. The identification string of the entity will then be provided to the holder by the CZ.NIC Association.
Actions
This section describes the most common types of decisions concerning domain names, the actions that the CZ.NIC Association performs on their basis, and the time frame within which these actions can technically be carried out.
Refrain from transferring the domain name to a third party, with the exception of the plaintiff
Refrain from publishing certain information using a domain name
Refrain from establishing a right of lien or other right to the domain name
The effect of some actions may not be immediate. This applies in particular to changes to name servers, where changes made on the primary name server are reflected on the other name servers with a delay that cannot be influenced by the CZ.NIC Association.
Procedure in the case that no decision is made concerning the obligation to transfer a domain name to the plaintiff
If a decision is made to cancel the registration of a domain name and no obligation to transfer the domain name to the plaintiff is imposed, the CZ.NIC Association shall cancel the registration of the domain name and the plaintiff shall have one month to apply for the registration of the same domain name.
Within this period, other applicants will not be allowed to register that domain name. This procedure (see article 19 of the Registration Rules ) is a reaction to the Supreme Court ruling stating that the proceedings relating to domain names cannot be used to claim domain name transfer as a remedy for a defective condition.
As a simple cancellation of registration might lead to the domain name being registered by an entity other than the plaintiff and such entity may violate the plaintiff's rights, thereby forcing the plaintiff to file a new complaint, the CZ.NIC Association has decided that in the case of a court order imposing the cancellation of a domain name registration, the plaintiff has the right (but not the obligation) to apply, within the prescribed period, for the registration of this domain name and the CZ.NIC Association will approve the application as a matter of priority.
