If Swi is right, and since Empire is from CA and CA courts could have jurisdiction over this matter, then Empire can file a complaint through youtube's appeal process under CA law.
I didn't really have enough time to look up the matter, but below is one statute that governs the matter under CA law:
§ 3344. Use of another's name, voice, signature, photograph, or likeness for advertising or selling or soliciting purposes
[SIZE=78%](a) Any person who knowingly uses another's name, voice, signature, photograph, or likeness, in any manner, on or in products, merchandise, or goods, or for purposes of advertising or selling, or soliciting purchases of, products, merchandise, goods or services, without such person's prior consent, or, in the case of a minor, the prior consent of his parent or legal guardian, shall be liable for any damages sustained by the person or persons injured as a result thereof. In addition, in any action brought under this section, the person who violated the section shall be liable to the injured party or parties in an amount equal to the greater of seven hundred fifty dollars ($750) or the actual damages suffered by him or her as a result of the unauthorized use, and any profits from the unauthorized use that are attributable to the use and are not taken into account in computing the actual damages. In establishing such profits, the injured party or parties are required to present proof only of the gross revenue attributable to such use, and the person who violated this section is required to prove his or her deductible expenses. Punitive damages may also be awarded to the injured party or parties. The prevailing party in any action under this section shall also be entitled to attorney's fees and costs.[/SIZE]
(b) As used in this section, “photograph” means any photograph or photographic reproduction, still or moving, or any videotape or live television transmission, of any person, such that the person is readily identifiable.
Sorry for the long message but I hope this helps. I really think this is a non-issue, I don't really mean to scare you, just trying to be informative for future cases that arise similarly to this.
