A Federal Court judge has ordered Australian internet service provider iiNet to disclose the details of customers who allegedly shared the film Dallas Buyers Club.

The landmark decision means that 4,700 people accused of illegally sharing the film online will likely be threatened with legal action by lawyers representing Dallas Buyers Club LLC, the company who owns the rights to the film.

iiNet will have to hand over names, email addresses and residential addresses of people alleged to have used torrenting sites to share the film.

In his ruling, Justice Nye Perram didn't set a limit for the amount of compensation that Dallas Buyers Club LLC could claim in the process, but ruled that he'd have to see any of the legal letters sent to customers first.
