What exactly happens if Musk just decides to 'ignore' the judgement and not pay anything? He'll get some angry e-mail from some irish government office and then that'll be that? Just appeal it and drag it out then ignore it? not sure there's many irish companies they'd lose business with if ireland cut X off
They have actual physical property and office equipment in Ireland. Typically and not unheard of they would send a professional to seize as much as needed, with the assistance of the police.
Generally a court order to seize goods. But most companies will just pay the judgement; companies need credit for efficient operation, and they are not granted the same leniency on delinquency that individuals are.
Well it is X ordered to pay, not Musk. But you are right, he is unlikely to approach this on an adult way, and will do anything he can to pretend to himself that he has won.
