Some laws of the Hong Kong Special Administrative Region have to come into force as soon as the transfer of government takes place.
These laws include the complicated legislation that determines who can have the right of abode and the simple one that makes July 1 a public holiday.
These laws have to be made before the handover.
Emigrants want to know with certainty whether June 30 will be a deadline for them to return and settle in the territory as permanent residents.
They would not want to be told they should look for the answer in an ordinance that will be passed some time after that date.
It would be equally ridiculous for the SAR legislature to meet on July 3 and pass a law telling the public that the two preceding days should have been a holiday.
