A more thorough explanation:

Atilian law is a law in Roman law that allows magistrates to appoint guardians. It is also known as Lex Atilia, which means "the law of Atilius". This law was proposed by a tribune named L. Atilius Regulus and was enacted around 210 B.C.

For example, if a child's parents die or are unable to take care of them, a magistrate can use the Atilian law to appoint a guardian to take care of the child. This ensures that the child is taken care of and protected.

The Atilian law is important because it helps to protect vulnerable individuals who may not have anyone to take care of them. It also gives magistrates the power to make important decisions that can affect people's lives in a positive way.
