A draft of a previously-secret treaty was made public on Wednesday, according to which internet service providers could become copyright Net-cops, who will have the authority to block access to suspected pirate Web sites.

Internet providers who will stop access to pirated material and adopt a policy dealing with illegal "transmission of materials protected by copyright" would be immune from lawsuits. They could face legal liability, if they don’t do so.

The copies of the Anti-Counterfeiting Trade Agreement (ACTA) are denied to civil libertarians and technologists, as both the Obama administration and the Bush administration had rejected their requests.

The European Parliament voted last month by a 633 to 13 margin, in favor of releasing ACTA's text which was kept secret. The nations which are participating include United States, the European Commission, Australia, Canada, Japan, and New Zealand.

Different nations have proposed much of the language in ACTA, which is not final. It fails to indicate whether the "disabling access" section will remain.

The recent ACTA negotiations in New Zealand were "constructive”, revealed the U. S. Trade Representative. The next meeting will be conducted in Switzerland in June.
