Day twelve of the trial between anti-piracy group AFACT and Aussie ISP iiNet. iiNet CEO Michael Malone was questioned by AFACT barrister Tony Bannon for the fourth consecutive day, this time about the world's largest tracker, The Pirate Bay, and any actions the ISP had taken to block customer access to it.

It’s day twelve in the copyright infringement case of AFACT – representing several Hollywood studios – and Aussie ISP iiNet (earlier coverage of day one, day two, day three, day four , day five, day six, day seven, day eight, day nine, day ten, day eleven.

The case continued Thursday in the Federal Court, with iiNet CEO Michael Malone taking the stand for the fourth consecutive day, and possibly his last.

Not unusually for a copyright trial involving BitTorrent, the issue of The Pirate Bay was raised.

Yesterday AFACT barrister Tony Bannon incorrectly suggested that iiNet’s very own BitTorrent tracker’s functionality had been taken down, later to discover that in fact the court’s network blocked BitTorrent transfers.

Bannon indicated that he would like to be able to give a courtroom demonstration of The Pirate Bay Thursday, and the judge agreed that it would be possible to lift the block so he could do so.

According to ITNews, Bannon was today true to his word.

After the demo, Bannon enquired of Malone whether iiNet had a desire for its subscribers to be able to access the world’s largest tracker, “…when the only purpose it serves is providing a way to download unauthorized copies of films?”

This question was met with objection from iiNet barrister Richard Cobden, who argued that customer “desire” was irrelevant to the case. The judge, Justice Cowdroy, was also keen to discover the relevance.

Bannon then became the latest in a long line of movie and music industry lawyers to reveal that should his clients win the case, they will take legal action to have not only the world’s largest tracker blocked from iiNet’s customers, but other similar sites.

He also revealed that around 50% of the alleged copyright infringements in the case came courtesy of The Pirate Bay.

Then Bannon attempted to show that by allowing its customers to access The Pirate Bay, iiNet effectively sanctioned and authorized their infringing activities.

“We seek Mr Malone’s position as to whether or not his customers should have access to sites such as this,” said Bannon.

However, after legal argument, Bannon withdrew the question.

Malone did, however, concede that iiNet had taken no steps to block The Pirate Bay, but qualified this by indicating that the company didn’t possess the means to do so. Bannon asked if it was technically possible and Malone replied that he could achieve a primitive block with additional equipment, but even that could be easily circumvented

“To completely and conclusively block access to The Pirate Bay, I believe it to be beyond our technical capability or of any ISP,” replied Malone.

Asked by Cobden if iiNet had ever blocked any web sites, Malone said the company had not.

This technical inability led to iiNet pulling out of the Australian government’s filtering trials, reports ComputerWorld. Malone has been an outspoken critic of the filtering scheme, labeling it “fundamentally flawed” and saying his company would only participate in the trials to prove that filtering would fail.

The case continues.
