A last-minute filibuster on the copyright amendment ordinance has bought a three- to four-week delay for angry internet users to fight for the withdrawal of a law they term the 'Article 23 of the cyber world'. Radical People Power lawmakers have filed more than 1,000 amendments, prompting the Legislative Council's House Committee to ask the government for a postponement of the second and third readings of the bill, originally due at a full council meeting on May 9. Opponents of the law are marshalling their forces for a last-ditch battle to scrap the law, which threatens to leave parodists facing criminal prosecution. 'At least we have earned more time to fight,' said Wong Yuk-man, a People Power lawmaker. 'We will mobilise internet users to take to the streets.' A spokeswoman for the Commerce and Economic Development Bureau said it would strive to co-operate with the legislature's work. The filibuster move came as other pan-democrats remained split on whether to support a government amendment - to which they had once agreed - that would exempt 'secondary creations' such as parodies, providing they did not affect the original authors' earnings, or create 'non-trivial economic loss'. Speaking after the weekly meeting of about 20 pan-democrats yesterday, Labour Party lawmaker Cyd Ho Sau-lan said they would firmly oppose the bill, but failed to reach consensus on the amendments. She said Civic Party lawmaker Ronny Tong Ka-wah and the Labour Party would maintain their support for the government's 'safety valve' amendment, aimed at reducing the chances of lampoonists and satirists facing criminal prosecution. But other Civic Party and Democratic Party members may backtrack, with Civic Party lawmaker Tanya Chan proposing a counter-amendment to protect all parodies unconditionally. 'We agreed to vote against the bill in both the second and third readings. But I hope if it is unlikely that we can vote down the bill, we can at least get the safety valve amendment passed,' Ho said. The bill and amendment need a simple majority to pass, but Chan's amendment would require a majority in both functional and geographical constituencies, adding to the difficulty in getting it passed. Given the delay, Ho said she would discuss with the pan-democrats how to muster internet users to fight the bill. A copyright infringement is now a criminal offence if it is for profit or when it leads to significant damage. The new bill seeks to extend the law to cover any kind of electronic media. Cally Yu Yeuk-mui, a writer who co-organised a petition for the bill to be dropped, said they would try to build momentum against what she sees as a malicious law. 'We want to see the bill ditched. But we need more discussion so that we can organise activities to speak out against it,' Yu said. Pan-democratic group NeoDemocrats will hold a protest tomorrow to oppose the bill.
