actually all these questioning are just to find out what kind of a case Odex has, since they are not the authority to prosecute acts of copyright infringement, nor do they own the copyright of the materials in question since they are only a distributor. and technically speaking, i still think AVPAS should be the one taking actions and not Odex, at least AVPAS can be considered a sort of representation of some copyright owners, Odex is only a distributor. although some equate AVPAS to Odex, i believe they have their functional distinction.
Odex may bring an action for infringement if they are the exclusive licencee of the anime titles. For criminal offences, only the public prosecutor may press charges for an offence.
