Can you sue someone for stealing a slice of pizza?
(Origin of question... a simple tease that someone took a little too seriously, and now I'm curious.)
The civil equivalent of theft is the tort of conversion, “consisting of "taking with the intent of exercising over the chattel an ownership inconsistent with the real owner's right of possession". In England & Wales, it is a tort of strict liability.”
According to the Brazilian Penal Code, if the person has the initial intention of stealing that slice of pizza, it is classified as theft under article 155 and there is no minimal threshold for value - proven by multiple cases of people being convicted and incarcerated for stealing things of insignificant value (like 10 BRL, which is less than 2 USD today)
There is a lot of discussion going on about establishing a minimum value for theft, but nothing concrete has come out of it as of yet
Another 2 possibilities that are rarely enforced but are still present in the penal code are under misappropriation
Furthermore, if someone ate a piece of pizza that didn't belong to them initially even if they had legitimate access to it (e.g. someone asked them to keep an eye on the pizza while they went to the toilet) they can be charged with misappropriation under article 168.
If they found a pizza or were mistakenly given an extra slice of pizza, article 169 gets you covered for "misappropriation of another person's property through error, happenstance or natural events".
Despite the popular saying, finders are NOT keepers!
Not that anyone would actually bother with prosecuting that and the police will probably laugh in your face
