Hasn't Lucas stated that he's cool with fan-films and actually encourages it as long as they don't try to sell/profit off it? I don't see how this is any different.
Does the state needs the victim's consent in order to prosecute a thief?
No (well, in the vast majority of legislations, anyway), theft being a crime.
Similarly, copyright infringement is a crime (it was criminalised in most countries since file-sharing/piracy/whatever).
The state doesn't need anyone's permision in order to prosecute this crime - and make no mistake, it's punishable by years in prison.
Copyright infringement only ceases to be a crime if Lucasfilm gave the fans the right to use the star wars brand.
'Gave' as in legally gave, not only giving them a pep-talk.
Conclusion - depending on the country they're citizens of, the fans who made this film are liable to spending the next few years in prison.
As a matter of case history the copyright owners can/do notify any site posting materials whether blog or stream and file a cease and desist order. Nearly universally they comply, But the copy holders must do this, these take downs are not spontaneous through the magic ether of the web. Lucas' Lawyers have not been shy of this in the past and nothing indicates this has changed. Point is they have standing, we , you do not. And I fail to see the relevance of you quoting copy right law as though you have standing. Why are you lecturing us, are you on a stump speech for SOPA.
Excuse my bluntness but your insistence is quite direct.
