What my post was trying to say is that there is no way the priest could have known, if he met her for the first time and never heard of her before, there wasn't enough to deny her communion. We know what she's like, but we don't have any statement or evidence to say that he knew, definitively, that she was a practicing lesbian Buddhist who has something against the Church, without making an assumption on the word "lover." Because he probably did not know enough, he was acting out on a hunch, something he cannot do. It must be public and well known; a priest can't deny just because he feels the person is in a state of sin- he must know it and it must be publicly known.
The only way it can really work at this point if the priest already knew about her beforehand, which no one has yet to claim.
