In recent years, the Czech courts have started invalidating validly concluded arbitration clauses and proclaiming them as being absolutely void. This affects also domain name disputes which can be (according to the national domain registry cz.nic) generally settled through arbitration but - according to the courts - such an arbitration clause will not be valid in disputes between entities (and will apply only in disputes vis-à- vis the domain registry).  

On a related note, effective as of December 2016, arbitration clauses will be banned in credit agreements for consumers; this means that all consumer disputes arising from such agreements will be resolved by regular courts only.
