If you pick a one member WIPO panel you are BRAIN-DEAD and CHEAP and the chances are you will lose your domain. It's that simple. Why even send the $1200? Just lay down!
So Berkens reported that a domain (canary.com) that should have been an EASY RDNH was actually lost because the domainer used a 1 member panel and I am not sure even with that how his attorney could lose, but they did. 1 member panels are the KISS OF DEATH and I have said it for years. You may as well just give them the domain and save a few grand.
So the valuable name Canary.com was transferred to the complainant because why?? Because the domain owner was Cheap or stupid or both? Pick your flavor.
