The result had been widely expected internationally and means that the agreement cannot become law in the European Union or any of its member states. The vote came after a last-ditch attempt by the European People's Party to have it delayed was shot down.

Digital civil liberties groups have hailed the result as a huge victory for citizens, following a concerted campaign to reject the anti-piracy agreement, which aims to enforce intellectual property rights.

ACTA was signed by the European Commission and 22 E.U. member states in January, but following widespread civil protests throughout Europe, many countries back-pedaled on their decision to sign. The major sticking point is the digital chapter, which protesters say leaves the door open for countries to force Internet service providers to police their own customers.

Parliamentarians were also angry that the deal was largely negotiated in secret and only came to light when an initial draft was released by Wikileaks in 2008. French member of the European Parliament, Kader Arif, responsible for assessing the agreement, resigned from his post in January calling the negotiations a masquerade.

And in April, Europe's top data privacy watchdog, the European Data Protection Supervisor, criticized the anti-piracy agreement, warning that it could lead to widespread monitoring of the Internet and breaches of individuals' right to privacy.
