I think the "actual objection" is the hardest part.
The UK Government might legitimately object to the registration of `dwpgov-uk-payments.pizza` but should they be allowed to object to `dwp-gov-uk-stole-my-payments.fart`?
One might be obviously dodgy, the other is someone ranting about their experience. Do you think Governments should be able to object to domains complaining about them?
