C.D. Cal. L.R. 83-1.3.1

It shall be the

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).

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.
