Direct legislation by the Standing Committee of the National People's Congress is likely to be completely inconsistent with the requirements of Hong Kong common law, and it is difficult to implement it in Hong Kong, so it is most convenient to move it back to the mainland for implementation. If this is the case, of course, it will be very detrimental to Hong Kong. Compared with the Fugitive Offenders Ordinance, Hong Kong has withdrawn the amendments to the Fugitive Offenders Ordinance. But in this way, even if the Fugitive Offenders Ordinance is not revised, it can still be "sent".
The actual situation is much ghost mannequin effect service worse. Under the Fugitive Offenders Ordinance, the "delivery" will also go through two procedures, including the Chief Executive's gazette and the court hearing.

The situation is also much worse than the enactment of Article 23 in Hong Kong.
If Hong Kong legislates for Article 23 early on, then all trials will be conducted in Hong Kong, in accordance with Hong Kong's legal procedures and conviction principles, and there will be lawyers defending them. It must meet the requirements of the Bill of Rights. There is no death penalty in Hong Kong, and even if the sentence is sentenced, it will be executed in Hong Kong. When everything is put on the mainland, this is not the case at all.
