Officials believe they have amended all laws that conflict with the Bill of Rights Ordinance.
The ordinance, enacted in 1991, allows the International Covenant on Civil and Political Rights to apply to the SAR.
The Government has amended 40 laws found to breach the covenant.
John Dean, principal assistant secretary for home affairs, told a provisional legislature bills committee: 'There is no existing legislation that seems to contradict the covenant, apart from the 40 identified.
'Are there any lurking? We don't know because we haven't found them.' Members criticised the Government's insistence on repealing an amendment - passed by the ousted legislature - which makes the ordinance binding on litigation between individuals.
'The Government failed to explain why the ordinance should remain relevant between the Government and public, and not among individuals,' said Bruce Liu Sing-lee of the Association for Democracy and People's Livelihood.
Deputy Secretary for Home Affairs Lo Yat-fai said the SAR's international reputation was at stake.
