Final answer:
Yes, you can "id" back to the last authority listed in a string citation.
Step-by-step explanation:
In legal citation, a string citation is a format used to cite multiple authorities in a single citation. When using the abbreviation "id" in a string citation, it refers back to the immediately preceding citation. Therefore, if you use "id" back to the last authority listed in a string cite, it means you are referring to the same source as the last citation in the string.
For example, let's say you have a string citation like this: (Smith v. Johnson, 2020; Brown v. Jones, 2018; id.). Using "id" in this case would mean you are referring back to the case of Brown v. Jones from 2018.
So, the statement "Can I 'id' back to the last authority listed in a string cite?" is True.
