What does Id mean in legal matters?

In legal matters, "Id." is an abbreviation for the Latin term "idem," meaning "the same." It is often used in legal citations to refer back to a previously cited source, allowing for brevity and clarity in legal writing. For example, if a case or statute has been cited earlier in a document, "Id." can be used in subsequent references to indicate that the same source is being cited again. This helps avoid redundancy and keeps legal texts concise.
