Proposed changes to civil liberties laws will go to the provisional legislature in the form of 'blue bills' before the handover, according to post-1997 executive councillor Henry Tang Ying-yen.
This means the interim body will conduct three readings on the bill before July 1 - a move the Democratic Party has vowed to challenge in court.
Mr Tang said blue bills would be tabled to replace the Public Order Ordinance and Societies Ordinance, which are to be partially scrapped by the National People's Congress Standing Committee.
The aim is to ensure the laws are passed before July 1 to eliminate the chance of a legal vacuum.
Mr Tang described the proposals as 'moderate and constructive', but declined to comment on whether they were more restrictive than the present laws.
'It is not a matter of tightening or loosening freedom. We have to seek the right balance between maintaining public order and complying with the international human rights covenants,' he said.
The office of Chief Executive-designate Tung Chee-hwa is about to issue a consultation paper on the issue.
