If you’ve downloaded this award winning film, you could be facing legal action.

If you’ve ever illegally downloaded the movie Dallas Buyers Club there could be a legal letter coming your way.

Following a landmark copyright ruling yesterday, Australian ISPs including iiNet, Internode, Dodo and Adam have been ordered by the Federal Court to disclose information about the thousands of customers who allegedly pirated the Matthew McConaughey film.

According to reports, 4726 IP addresses were found to have downloaded the film. Dallas Buyers Club LLC will have to submit all letters to the court for approval before sending them out.

However, there is a light at the end of the tunnel, as legal experts have come out and said that even if you’re identified as a potential pirate there are several reasons you could defend the claims.

iiNet’s former chief regulatory officer, Steve Dalby, told Fairfax Media that while parties found to be guilty would have no defence, it was tough for Hollywood studios to prove it.

“Remember that the letter is not proof and is only an allegation,” he said. “They can’t detect downloaders so if I downloaded it but never shared it I wouldn’t be concerned about it.”

“If you do receive a letter from Dallas Buyers Club claiming you’ve illegally downloaded a film, it’s important to seek legal advice and also consider whether anyone else may have been sharing your network.”

Technology website ZDNet journalist Josh Taylor told the ABC that the decision would “probably scare a few people”, but that it was not the most effective way to stop piracy.

“I don’t think that scaring people into stopping downloading is the most effective way of doing it,” he said. “The most effective thing you can do is make the content available in a timely and affordable manner and we are getting to that stage now.”

Will this new ruling change your downloading habits?
