Austrian ISPs have been told they have just days to block not only The Pirate Bay but also Movie4K, one of the world's most famous streaming sites. The blockades, which were demanded by Hollywood-backed anti-piracy outfit VAP, are supported by recent decisions from both the Supreme Court in Austria and the European Court of Justice.

Kino.to, one of Germany’s largest illegal streaming portals, was shut down during 2011 following the largest law enforcement action against of its type in Europe. But even with the site long gone the disruption it caused is about to affect The Pirate Bay and two other major sites.

Just a month before Kino.to was dismantled in June 2011, Austrian ISP ‘UPC’ was served with a preliminary injunction ordering it to block subscriber access to the site. Verein für Anti-Piraterie der österreichischen Film und Videobranche (VAP) – the anti-piracy association of the Austrian film and video industry – had been on the warpath since 2010 and had finally got their way after UPC refused to comply voluntarily.

But would blocking the site be legal? UPC insisted that it couldn’t be held responsible for a site it had nothing to do with. The ISP also maintained that there had been no court ruling determining that UPC customers who accessed Kino.to were breaking the law.

To settle the matter once and for all the Austrian Supreme Court asked the European Court of Justice to clarify whether a company that provides Internet access to people using an illegal website could be required to block that site. On March 27, 2014, the ECJ handed down its decision.

On UPC’s first point the Court said that EU law does not require a specific relationship between the person infringing copyright and the intermediary against whom any injunction had been issued. On the second point the Court said that proof of illegality was not necessary as the law exists not only to bring an end to infringement, but also to prevent it.

The key point of the ruling was that ISPs can indeed be required to block access to infringing sites provided that injunctions are both balanced and proportional. As a result, earlier this month Austria’s Supreme Court found that the blockade against Kino.to, even though the site is long dead, was correctly applied.

On the back of this ruling, this week VAP wrote to several local ISPs, UPC included, demanding a new blockade of three domains – ThePirateBay.se, Movie4K.to and Kinox.to, a site that took over from Kino.to.

“Letters dated yesterday have been sent to four large ISPs containing a request to block a small number of websites,” VAP Managing Director Werner Müller told Future Zone.

On behalf of three local movie companies (Allegro Film, Wega Film and Epo Film) VAP has requested IP address and DNS blocks of the three sites but has given the ISPs very little time in which to carry them out, by this Friday August 1, to be exact.

The Association of Internet Service Providers Austria (ISPA) feels the deadline is far too restrictive.

“The period given to the providers to act is ludicrously short. We see this as very problematic. Extreme pressure is being exerted,” Secretary General Maximilian Schubert said.

“Two working days during the holiday season is just too little. To implement this by Friday we deem too difficult.”

Interestingly, Schubert also sees differences between The Pirate Bay and the pair of streaming portals listed in VAP’s blocking request.

“There is also legal content on The Pirate Bay,” Schubert said.

Discussions between VAP and the ISPs are scheduled for later in the week, so whether the anti-piracy group will get its way immediately will remain to be seen. They’ve waited years already, another few days shouldn’t make much difference.

Update: The ISPs were given two more weeks to block The Pirate Bay.
