28 CFR 51.29 - Communications concerning voting changes.
(a) Communications may be in the form of a letter stating the name, address, and telephone number of the individual or group, describing the alleged change affecting voting and setting forth evidence regarding whether the change has or does not have a discriminatory purpose or effect, or simply bringing to the attention of the Attorney General the fact that a voting change has occurred.
(b) Comments should be sent to the Chief, Voting Section, Civil Rights Division, at the addresses, telefacsimile number, or email address specified in § 51.24. The first page and the envelope (if any) should be marked: “Comment under section 5 of the Voting Rights Act.” Comments should include, where available, the name of the jurisdiction and the Attorney General's file number (YYYY-NNNN) in the subject line.
(c) Comments by individuals or groups concerning any change affecting voting may be sent at any time; however, individuals and groups are encouraged to comment as soon as they learn of the change.
(d) To the extent permitted by the Freedom of Information Act, 5 U.S.C. 552, the Attorney General shall not disclose to any person outside the Department of Justice the identity of any individual or entity providing information on a submission or the administration of section 5 where the individual or entity has requested confidentiality; an assurance of confidentiality may reasonably be implied from the circumstances of the communication; disclosure could reasonably be expected to constitute an unwarranted invasion of personal privacy under 5 U.S.C. 552; or disclosure is prohibited by any applicable provisions of federal law.
(e) When an individual or group desires the Attorney General to consider information that was supplied in connection with an earlier submission, it is not necessary to resubmit the information but merely to identify the earlier submission and the relevant information.
