An Illinois Subpoena Ducks Cecum is a legal document issued by a court in the state of Illinois which compels a person or organization to produce documents or other tangible evidence for use in a legal proceeding. It is a powerful tool that allows a party to obtain evidence that would otherwise not be available to them. There are two types of Illinois Subpoena Ducks Cecum: a Regular Subpoena Ducks Cecum and a Subpoena Ducks Cecum for Grand Jury Proceedings. A Regular Subpoena Ducks Cecum is used when a party to a civil or criminal case needs to obtain documents or other tangible evidence from a non-party. The subpoena will specify the documents or other tangible evidence, such as records, photographs, or other items, that must be produced. It can also specify a date and time for the production. The party requesting the documents has the burden of showing that the documents are relevant to the case and that they are necessary for the case. A Subpoena Ducks Cecum for Grand Jury Proceedings is used when a grand jury needs to obtain documents or other tangible evidence from a non-party. The subpoena will specify the documents or other tangible evidence that must be produced. Unlike a regular subpoena, the grand jury does not need to show that the documents are relevant to the case or necessary for the case. The documents or other tangible evidence will be used to determine whether there is sufficient evidence to bring criminal charges against a person or organization.
