Lawmakers have dealt with fewer than 20 per cent of the bills they are supposed to pass this session, raising fears of a huge backlog over the next few months. With the legislative session halfway through, Legco records show only 10 bills have been passed in the 15 sittings since October. Up to 35 bills are still being vetted or are due to be tabled in the next few weeks. Of those, 22 are left over from the 2000-01 session. The backlog is expected to swell further - the Government plans to submit 20 more bills, taking the number scheduled for this session to 65. Lawmakers will have to squeeze through about four bills in each of the remaining 15 sittings if they want to clear them before Legco's summer recess. Fred Li Wah-ming, Legco House Committee vice-chairman, attributed the slow progress to a change in attitude among members. 'We have been more cautious in scrutinising the bills following the copyright law saga. We don't want to compromise the quality,' he said. The Democrat Party legislator was referring to confusion arising from the tightening of the Copyright Ordinance last April. Lawmakers and officials were criticised for overlooking the impact of criminalising unauthorised photocopying of newspapers. A bill to suspend some of the provisions was later passed. Mr Li said some bills, such as one concerning licensing of karaoke parlours, affected business interests and required close scrutiny. Members often had clashes in attending different committees, which also stalled progress, he added. 'Some never attend bills committees, while some joined six to seven committees at the same time. It's always a problem,' said Mr Li. He dismissed concerns of a huge backlog by the end of the session in July, and also said he would not press his colleagues to speed up the vetting. 'I don't think we should speed up at the expense of quality,' he said.
