A more thorough explanation:

Libellus accusatorius is a Latin term used in Roman law to refer to a written criminal accusation.

An example of libellus accusatorius would be a written accusation of theft against a person. The accuser would write down the details of the alleged theft and present it to the authorities as evidence.

Another example would be a written accusation of murder. The accuser would write down the details of the crime and present it to the authorities as evidence.

Libellus accusatorius is a formal way of making a criminal accusation in Roman law. It involves writing down the details of the alleged crime and presenting it to the authorities as evidence. This written accusation is important because it provides a clear record of the allegations and can be used as evidence in court.

The examples illustrate how libellus accusatorius was used in Roman law to make criminal accusations. In both cases, the accuser wrote down the details of the alleged crime and presented it to the authorities as evidence. This written accusation would then be used in court to determine the guilt or innocence of the accused.
