Hello Emma - it's possible to dispute anything but the key Q is really would that dispute be settled by our own actions, those of the parties in dispute or for example legal action/a court.
The processing of a UN1 is explained in PG 19 -
Notices, restrictions and protection of third-party interests (PG19) - GOV.UK
All things are possible as a UN application is invariably a statement of the interest involved without any supporting documentation. If someone is 'adamant' about something then I assume they have documentary proof of any referral to the Tribunal. And yes they would have the specific details you mention
