What term is defined as the devices or tools used by one side to obtain facts and information about a case?

The term that describes the devices or tools used by one side to obtain facts and information about a case is discovery. Discovery is a legal process used in litigation where parties gather information from each other to prepare for trial. It includes various methods such as written questions, requests for documents, and oral depositions, allowing each side to understand the facts and the evidence that will be presented.

While evidence refers to the information and material presented in court to support or refute claims, and interrogatories and depositions are specific mechanisms used within the broader discovery process, discovery as a whole encompasses all techniques aimed at gathering pertinent information prior to a trial. Therefore, discovery is the overarching term that accurately captures the essence of obtaining facts and information related to a case.
