responsibility of the parties to promptly file a Notice of Related
Cases whenever two or more civil cases filed in this District:
(a) arise from the same or a closely related transaction,
happening, or event;
(b) call for determination of the same or substantially related
or similar questions of law and fact; or
(c) for other reasons would entail substantial duplication of
labor if heard by different judges.
That cases may involve the same patent, trademark, or
copyright does not, by itself, constitute a circumstance
contemplated by (a), (b), or (c).

LOCAL RULES - CENTRAL DISTRICT OF CALIFORNIA
The Notice of Related Cases must include a brief factual
statement that explains how the cases in question are related
under the foregoing factors. All facts that appear relevant to
such a determination must be set forth.
The Notice must be filed at the time any case (including a
notice of removal or bankruptcy appeal) appearing to relate to
another is filed, or as soon thereafter as it reasonably should
appear that the case relates to another. The Notice must be
served on all parties who have appeared in the case and
concurrently with service of the complaint.
