A more thorough explanation:

VERSARI IN RE ILLICITA

Versari in re illicita is a Latin term that means to be engaged in an unlawful activity. This can be used as a bar to a claim for damages, meaning that if someone is engaged in illegal activity and gets hurt, they may not be able to sue for damages.

For example, if someone is injured while committing a crime, they may not be able to sue for damages because they were engaged in an unlawful activity. Similarly, if someone is injured while trespassing on someone else's property, they may not be able to sue for damages because they were engaged in an illegal activity.

Another example could be if someone is injured while driving under the influence of drugs or alcohol. They may not be able to sue for damages because they were engaged in an illegal activity at the time of the accident.

The examples illustrate the definition of versari in re illicita because in each case, the person who was injured was engaged in an illegal activity at the time of the injury. This means that they may not be able to sue for damages because their own illegal actions contributed to their injury.
