In extraordinary situations, when the interest of justice requires, the General Counsel may waive or suspend the rules of this part, sua sponte or on petition of an interested party, subject to such requirements as the General Counsel may impose on the parties. However, the inclusion of certain legal processes within the scope of these rules, e.g., state legal proceedings, does not represent a waiver of any claim of immunity, privilege, or other defense by the Office in a legal proceeding, including but not limited to, sovereign immunity, preemption, or lack of relevance. This rule does not create any right or benefit, substantive or procedural, enforceable at law by a party against the Copyright Office, the Library of Congress, or the United States.
