The book “Making Saints” by Kenneth Woodward says that theologians are split on whether or not canonisations are Infallible. But if I remember right, the Catholic Almanac says that canonisations are. I’m inclined to agree. I can’t seem to find anything definitive that says it for sure though, and I doubt anything out there really confirms it or not.
No, but their cultus can be “suppressed.” The Beatification isn’t undone, but the extent to which they are venerated would be limited. For example, their Feast Day is taken off the Calendar.
BUT there is a peculiar case of a Beatification that was approved and scheduled, but canceled and suspended. John Paul II approved the Beatification for the French Father Leon Dehon. It was scheduled for 24 April 2005. The Pope died on 2 April so they had to delay it. Then they discovered anti-Semitic writings from Father Dehon, so Benedict XVI suspended it, had a commission study it, then it didn’t go on. So apparently they weren’t thorough enough when they investigated his life.
I don’t doubt that he’s in heaven though, because there was a miracle through his intercession (for all we know, he sinned with his anti-Semitic remarks but got absolution for it afterward and repented – who knows? It’s not like saints never sinned). The canceled beatification isn’t the Vatican saying, whoops, the guy isn’t in heaven. Rather, it’s them saying, beatified people are supposed to have their examples followed, and we don’t want you following this guy’s example. He may be in heaven, you can pray to him yourself if you want, but we’re not promoting anti-Semitism, so the cause stops here.
But, I can’t help but wonder what would have happened if these writings came out after he was beatified. Of course the press that the Holy Father would have to endure would be unfair – he wasn’t even the one who approved of the beatification – and would be another PR disaster to waste the Vatican’s time.
I asked similar questions to yours on this thread

It is about whether or not beatifications can be by mistake, though my question deals more with martyrs and groups.
My thing is, we know Purgatory exists because of that story in the Bible where people were martyred fighting for God but they had idols of pagans on them, so they couldn’t immediately go into heaven. Today, isn’t it possible that a martyr is also in purgatory? We’d need a miracle to prove that they’re in heaven, but we know from the Bible that it’s possible for a martyr not to be, right? Miracles aren’t needed to beatify martyrs, so how do we know where they are? Martyrdom apparently isn’t a guarentee into heaven.
Or in groups of people who are beatified together, how do we know that the intercession is not done by only *one *of those people, and why is it safe to presume that the
entire group interceded?
Furthermore, the Catechism says that people in purgatory can pray for us; so how do we know that the person we prayed to isn’t in purgatory and was able to intercede for us from there?
For me, it’s just one of those times that I trust the Vatican knows what it’s doing. I just know they know better than I do. I don’t question if these people are in heaven; it’s not that I blindly follow, but I just know they’re the experts at this, and like you I’m interested in the process of how they got to that conclusion. The miracle needed for a canonisation is seen as God’s stamp of approval anyway.
