BT has been given just two weeks to block access to illegal download site Newzbin2.

The deadline was issued to the telecoms company by Justice Arnold, who has been presiding over a High Court case started by the Motion Picture Association (MPA) in June this year. Justice Arnold ruled in July that BT must prevent UK web users from accessing the site but did not set a timeframe.

The MPA hoped its legal action would force BT to prevent Brits from accessing Newzbin2, a members-only site that offers links to other locations on the web where music, movies and other content can be illegally downloaded.

The MPA initially started legal action against the original Newzbin in 2010, which resulted in the site being ordered to remove any material that infringed copyrights. However, Newzbin went into administration and was subsequently sold to new owners and launched again as Newzbin2 from the Seychelles. Because of this, and the fact that site's owners have already revealed they have created software that can circumnavigate the block, Justice Arnold said BT must also block "any other IP address or URL whose sole or predominant purpose is to enable or facilitate access to the Newzbin website".

"Furthermore, I do not consider that the studios should be obliged to return to court for an order in respect of every single IP address or URL that the operators of Newzbin2 may use."

Under Justice Arnold's original ruling BT is required to use its own Cleanfeed technology, which is already used to block access to websites containing child sex abuse images, to prevent access to Newzbin2.

The Judge also ruled it is BT's responsibility to cover the costs of implementing the website blocking technology.

"This is a win for the creative sector. Securing the intervention of the ISPs was the only way to put the commercial pirates out of reach for the majority of consumers," said Chris Marcich, president and managing director of the MPA.

"This move means that we can invest more in our own digital offerings, delivering higher quality and more variety of products to the consumer."
