What does the abbreviation "Id." signify in legal citations?

The abbreviation "Id." signifies "the same as a previously cited source." In legal writing and citations, "Id." is used to refer readers back to the last source cited in the text. This abbreviation helps streamline citations and avoids redundancy, allowing for clearer and more concise legal documents. By utilizing "Id.," the writer indicates that the current citation is to the same authority as the one immediately preceding it, thus maintaining the relevance and context of the legal argument without unnecessary repetition of the full citation details.

Other options, such as referencing a specific case name, pointing to statutes, or introducing a new source of law, do not accurately describe the function of "Id." in legal citations. Each of those options deals with different aspects of legal referencing, while "Id." specifically relates to reaffirming a direct connection to a preceding source. This is pivotal in legal writing to maintain clarity and brevity for readers familiar with the cited material.
