Recently, I saw some articles about how a Catholic priest got defrocked following his arrest for performing indecent activities in a public place, after a bystander walking past his church one night noticed that the lights were on, and looked through a window and saw him on top of the church's altar with a couple of dominatrices.

The articles I've seen go on to specify that once the local archbishop was made aware of this, he had the altar disposed of by burning and replaced with a new one.

This got me wondering: the Catholic Church is well known for having piles and piles of rules and regulations governing its activities, and I wondered if the way that the archbishop responded to this event was mandated by those rules, or if he was acting on his own recognizance.

Does the Catholic Church have any rules for how to dispose of profaned church altars? If so, does it mandate that they be burned?
