Can a Registry Operator impose trademark related registration requirements during the Sunrise Period and curtail or eliminate these requirements in subsequent registration periods?

During a Sunrise Period, a Registry Operator may apply restrictions related to the underlying rights of a trademark record as long as those restrictions are related to the purpose of the TLD. For example, if the purpose of a TLD was to serve a particular region, the Registry Operator could require that the trademark record be registered in that jurisdiction in order to be eligible for the Sunrise Period. However, if having a trademark from any jurisdiction meets the eligibility requirements to register a domain name in a subsequent registration period, the subsequent registration period eligibility requirements may be seen as evidence that the jurisdiction restriction in the Sunrise Period was not actually related to the purpose of the TLD.
