This morning Singapore became the latest in a line of countries to crack down on copyright infringement via web blocking. Fresh amendments to existing law will allow content owners to obtain injunctions from the High Court to block sites said to be engaged in widespread copyright infringement. Top of the list: The Pirate Bay

The battle to stop Internet users from downloading copyrighted material is one that can never be won, but that hasn’t stopped a growing list of countries from having a go.

Domain blocking is now one of the preferred methods of reducing copyright infringement around Europe and is endorsed by none other than MPAA chief Chris Dodd.

Today, Singapore can be added to the list of site-blocking countries after passing freshing amendments to its Copyright Act. The news, unpopular with many Internet users, caused the term ‘piracy’ to trend on Twitter.

The Bill was put before Parliament yesterday but was pushed over to today after time ran out. The newly-passed legislation will allow copyright holders to obtain High Court orders to force local service providers to block access to websites that “flagrantly infringe” copyright. How that will be determined is not yet clear.

The new tool will be a useful one for music and movie companies. Previously content was taken down or blocked by ISPs on a case-by-case basis but now wholesale site blocking will become the favored weapon. Local media suggests that the new mechanism could allow sites to be blocked within eight weeks of a successful application.

In a statement, Senior Minister of State for Law Indranee Rajah said the new amendments will help reduce piracy and boost legal alternatives.

“The prevalence of online piracy in Singapore turns customers away from legitimate content and adversely affects Singapore’s creative sector,” Rajah said.

“It can also undermine our reputation as a society that respects the protection of intellectual property.”

Unsurprisingly The Pirate Bay is first on the list of sites set to be targeted by copyright holders, with KickassTorrents reportedly a close second. The law could come into force by the end of August so it’s possible that both sites – and most probably more – will be blocked before the end of the year.
