A European data protection watchdog has added its voice to growing criticism of proposed anti-piracy legislation.

The European Data Protection Supervisor (EDPS) said that the Anti-Counterfeiting Trade Agreement (Acta) might have "unacceptable side effects" on individual rights.

Acta must be rubber-stamped by the European Parliament to come into force.

The MEP responsible for recommending which way lawmakers should vote has already said it should be rejected.

David Martin, the Parliament's rapporteur on Acta, said last week that politicians would not be able to "guarantee adequate protection for citizens' rights" if the treaty was ratified.

To date 22 member states, including the UK, have signed up.

A debate on the EU's adoption of the treaty is expected in June.

EDPS warned that any large scale monitoring of citizens' use of the internet would be disproportionate.

"While more international co-operation is needed for the enforcement of IP rights, the means envisaged must not come at the expense of the fundamental rights of individuals," said Giovanni Buttarelli, assistant European data protection supervisor.

"A right balance between the fight against IP infringement and the rights to privacy and data protection must be respected. It appears that Acta has not been fully successful in this respect."

Earlier this year, thousands of protesters demonstrated in cities including Berlin and Warsaw to share their objection to the agreement, which critics say will stifle freedom on the internet.
