A lot of the issues that end up being pushed to ICANN aren’t ICANN issues at all and are disputes between 3rd parties. We see this all the time.
If the third parties are engaged in registering / re-registering domain names - ccTLD or gTLDs delegated by ICANN - with or without ICANN accreditation, what happens to the domain name due to a dispute between the 3rd parties is still an ICANN issue.
