Finally, as I’ve said many times, canon law imposes excommunication only for a very narrow range of actions; renting space to an abortion clinic isn’t among them. Maybe it ought to be, and maybe there’s some other way to visit penal consequences on what is obviously an objectively gravely immoral action; but as of now, even if the right diocesan officers were citing the most relevant canons, there is no excommunication in canon law for the act described.
