(1) Designation of part of document as evidence. A party that offers only a portion of a document for admission into the evidentiary record must designate that portion as a separate exhibit. If irrelevant matter included in the original document would unnecessarily encumber the record, the presiding officer may admit only the offered portion into evidence but will allow other parties to offer other portions.

(2) Government records. A party may offer into evidence an official document prepared and issued by any governmental authority that is not publicly available or readily accessible by all parties in the form of a certified copy.

(3) Objections. Any evidence offered is subject to appropriate and timely objection. The presiding officer need not specifically ask each party whether that party objects to an offer of evidence or other motion or proposed action. Parties that have objections must state them. Failure to object constitutes a waiver of the right to object.
