Communications Act. Zuffa's claims relate to the "stealing cable" provisions. Justin.tv claimed that 47 USC 230 applies, a pretty logical argument given that Zuffa is bringing a non-IP claim against Justin.tv for third party content. However, the court sidesteps the Section 230 issue, saying it's never been applied to the Communications Act (true) and that the court couldn't find any analogous "stealing cable" claim against websites, and it didn't want to touch this "novel" issue.
Instead, the court dismisses the "stealing cable" claim on its elements. The court says:
In essence, Zuffa alleges that Justin.tv’s users copied Zuffa’s UFC event and then rebroadcast the UFC event over the internet. This is not the type of conduct properly addressed by the Communications Act, but by copyright law (and, potentially, trademark law) because Justin.tv had no relationship with the original cable or satellite signal: by the allegations, Justin.tv did not receive or intercept any actual cable or satellite signal or broadcast. The Court finds no evidence in the statutory language, other cases, or legislative history that the Communications Act addresses this type of conduct or was meant to bolster or act as a separate type of copyright claim.LINK
