Not done in the name of extradition

Human rights concerns have made it difficult for China to conclude extradition treaties with foreign states.[4] However, China is known to have persuaded foreign states to apply their immigration laws to repatriate criminal suspects to mainland China, in the absence of an official extradition agreement.[5] Mainland China, Hong Kong and Macau have adopted a similar practice to circumvent the problem of a lack of legal arrangements. Many of the transfers were carried out in the name of “repatriation”. Between 2000 and 2015, the police authorities of mainland China “repatriated” 170 criminal suspects to Hong Kong.[6] Often, news reporters are invited to cover the deportation of a permanent resident of Hong Kong (or Macau) who allegedly committed a crime in Hong Kong (or Macau) from mainland China to Hong Kong (or Macau).[7]

However, extradition in the opposite direction (from Hong Kong or Macau to mainland China) is more complicated. Macau’s Court of Final Appeal (TUI) consistently held that in the absence of laws governing cooperation in criminal matters with mainland China, Macau authorities could not detain and transfer criminal suspects to mainland China. In TUI case 12/2007, the court granted habeas corpus to a Hong Kong woman who was taken into custody by the Macau police at a border checkpoint awaiting transfer to mainland China to face a criminal investigation. After the 12/2007 ruling, the Macau authorities sought ways to circumvent potential legal challenges. In TUI case 3/2008 — a second case of a similar nature as case 12/2007, the Macau police transferred the suspect to mainland China before the TUI could render a decision. In the judgement, TUI criticised the Macau police for acts “contrary to justice and undermining the rule of law”. Yet, the TUI terminated the proceedings because the objective of the proceedings — the release of the detained person — had become impossible.

Some transfers from Hong Kong and Macau to mainland China sparked controversies. In 2008, former Tiananmen student activist Zhou Yongjun who had spent years in exile in the US, on his arrival in Hong Kong, was transferred by Hong Kong to mainland China.[8] The extrajudicial transfer of Zhou was heavily criticised by pro-democracy politicians in Hong Kong.[9] On the other hand, in 2015, in Macau police’s repeated defiance of the TUI 3/2008 ruling, Macau handed former Chinese official Wu Quanshen who had been granted non-permanent residence status in Macau over to mainland China to face corruption charges.[10] Macau official defended the transfer as “deportation”, instead of “surrender of fugitives”, following the revocation of Wu’s residence permit.[11]

The exclusion of mainland China from the applicability of the extradition laws in Hong Kong and Macau is hailed as protection by pro-democracy activists and politicians.[12] There are huge differences between the criminal systems of mainland China, Hong Kong and Macau. The death penalty is a lawful form of punishment in mainland China[13] but is outlawed in Hong Kong[14] and Macau[15]. Life imprisonment is lawful in mainland China[16] and Hong Kong[17] but is outlawed in Macau[18]. Also, in practice, the amount of evidence required for a criminal conviction is low in mainland China.[19] There have been numerous reports that the mainland China authorities often abuse the criminal justice system to harass political dissidents and rights-defending activists.[20]

International Covenant on Civil and Political Rights (ICCPR)

Articles 6 and 7 of the ICCPR impose obligations on party states not to extradite, expel or refoul individuals to another state where there may be a risk of the death penalty or the danger of torture or cruel, inhuman or degrading treatment.

During the second review[27] by the Human Rights Committee (HRC) on the ratification of the ICCPR in Macau in 1999, which took place months prior to Macau’s change of sovereignty, members of the HRC raised a series of questions to Portugal concerning the transfer of criminal suspects to mainland China from Macau. Ms Evatt asked Portugal whether “people would be more likely to be removed from Macau to mainland China, where they might face the death penalty”[28] after Macau’s return to China[29].

Portugal replied to the HRC that Portuguese courts had ruled in favour of refusals of extradition to China in view of possible death sentences.[30] Both the HRC and Portugal noted that the refusals had angered the Chinese government as China claimed that “an extradition agreement was not strictly necessary for the removal of prisoners”[31]. Moreover, Portugal said that it intended to conclude an agreement with China to make sure that the existing principles on extradition would subsist beyond 1999.[32]

In 2013, the HRC reviewed Macau for the first time after the change to Chinese sovereignty. The HRC reiterated the death penalty risk issue.[33] In reply to the HRC, Macau cited the rulings in TUI cases 12/2007 and 3/2008 to show that Macau had declined surrender of fugitives to mainland China after 1999.[34] The HRC concluded that “reaching a firm agreement” with mainland China would be “a matter of priority” for Macau.[35] Also, HRC emphasised that “[Macau] should ensure that the agreement is in line with its obligations under articles 6 and 7 of the [ICCPR]”.[36]

Convention against Torture and Other Cruel, Inhuman or Degrading Treatment or Punishment (CAT)

Article 2 of CAT requires state parties to prevent and to refrain from acts of torture. Article 3 of CAT requires state parties not to repatriate or “extradite a person to another State where there are substantial grounds for believing that he would be in danger of being subjected to torture”.

In 2008, the Committee against Torture (CtAT) asked Hong Kong “any progress with respect to arrangements between [mainland China] and [Hong Kong] for the transfer of fugitive offenders […]”.[40] In reply to CtAT, Hong Kong said the discussion was “ongoing” and “death penalty” would be “one of the usual safeguards found in [Hong Kong’s] agreements on surrender of fugitive offenders”.[41] In CAT’s concluding observations, Hong Kong was asked to provide more information on the requirements for the death penalty safeguard and the number of relevant cases.[42]

In 2014 and 2015, it was reported in the news that Macau was in negotiation with Hong Kong and mainland China on extradition agreements.[43] Both Macau and Hong Kong governments refused to disclose the terms.[44] The New Macau Association (NMA), a civil society organisation in Macau, reported the non-transparency of draft agreements and the Wu Quanshen case to the CtAT ahead of its review on China.[45]

In 2015, the CtAT raised the question on the extradition agreements between Chinese territories under negotiation.[46] Indeed, the manner in which the question on extradition was put by the CtAT in 2015 was not that different from those put by HRC and CtAT back in 2008 and 2013. However, at this meeting, the delegation made an objection to the extradition question by rejecting the application of international law to “internal affairs” under Chinese sovereignty.[47]

In the CtAT’s concluding observations on Hong Kong and Macau, the CtAT took notice of China’s claim that “internal affairs could not be considered as extradition agreements that would fall under articles 3 or 8 of the [CAT]”.[48] Notwithstanding the Chinese objection, the CtAT insisted that Hong Kong “is under an obligation to prevent transferred offenders or sentenced persons from being exposed to the risk of torture or ill-treatment … upon return to mainland China”[49]. The same comment also appeared in the CtAT’s observations on Macau.[50]

Making human rights treaties inapplicable

At least, there is evidence that the HRC interpreted that international law would apply to extraditions from Macau to mainland China after Macau’s revert to Chinese sovereignty. Also, the HRC was concerned whether the same protection accorded by the Portuguese government against extradition requests from China would continue to apply once Macau became under Chinese rule.

Perhaps, historical background made these former colonies special. When the ICCPR and CAT first became applicable in Hong Kong and Macau, the territories were not under Chinese administration. When the HRC reviewed Macau in 1996 and 1999, the HRC saw non-transfers of suspects to mainland China where the persons might face the death penalty as a safeguard which ought to continue beyond the return to Chinese rule, in the interest of articles 6 and 7 of the ICCPR.

Also, in the context of treaty bodies’ past reviews on Hong Kong and Macau, the “internal affairs” objection seemed out of place. At the 2008 CtAT review and the 2013 HRC review, China did not have a problem answering to questions about the “internal transfers” of fugitives from Hong Kong and Macau to mainland China. The 2015 CtAT review can be seen as a watershed moment that China became more judgmental of the scope of application of the international human rights instruments in Hong Kong and Macau.

The inconsistency in China’s views on the application of international human rights law to Hong Kong and Macau may seem trivial. Nonetheless, the attitude change suggests that China is adopting an even more defensive posture in its human rights records.
