It is now generally accepted that if, in a domain name case, the Respondent (the registrant) consents to the transfer of the domain name to the Complainant (the trademark owner), the Panel may, and probably should, just order the transfer without making findings of fact and without analysing the three prongs under the UDRP.
There are quite a few decided cases where this has been done and they are useful to cite if you have such a case.
You may now add a new case to the list[1]:
Navy Federal Credit Union v. DOMAIN MAY BE FOR SALE, CHECK AFTERNIC.COM Domain Admin / Domain Registries Foundation, FA1708001743401 (September 13, 2017).
[1] The Hon Neil Brown QC was the Panellist in this case.
