Interrogatories

In law, interrogatories (also known as requests for further information) are a formal set of written questions propounded by one litigant and required to be answered by an adversary, in order to clarify matters of fact and help to determine in advance what facts will be presented at any trial in the case.

In civil cases, the issues to be decided can potentially be more complex than in criminal cases. For example if a person is charged with speeding, in a hypothetical case the prosecution has to prove that the person was the driver of the motor vehicle and that it was being driven in excess of the proper speed without any lawful excuse.
