· It was no answer, in Chen, that the consequences likely to befall the child if returned to China resulted from the parents' financial inability to mitigate the consequences of the adverse treatment.
26 It may be noted that, except so far as causation is reflected in the propositions we have set out, it was not the subject of direct comment in the joint judgment.
27 Kirby J delivered, as we have said, a separate judgment. His Honour drew attention to the humanitarian purpose of the Convention. His Honour, too, pointed to the need to consider the definition as a whole, rather than "atomising" the concept it contains. Like the rest of the Court, his Honour rejected the submission that it was necessary, to show persecution, that the conduct in question be motivated by malignity, enmity or adverse intention. That was sufficient to dispose of the appeal. However, his Honour then turned to what his Honour referred to as "the causation point".
28 His Honour noted that causation was an issue which bedevilled the law in many aspects and depended upon the context in which it arose. His Honour noted that in the law of torts a "but for" test had to be tempered by "the infusion of policy considerations", citing March v E and MH Stramare Pty Ltd (1991) 171 CLR 506 at 515-7 as authority for this proposition. However his Honour then said, at 68, in a passage with which, with respect, we agree:
"In the context of the expression 'for reasons of' in the Convention, it is neither practicable nor desirable to attempt to formulate 'rules' or 'principles' which can be substituted for the Convention language."
29 So, his Honour said, it was necessary for the decision maker to "evaluate the postulated connection between the asserted fear of persecution and the ground suggested to give rise to that fear", bearing in mind the "broad policy of the Convention".
30 As his Honour thereafter points out, there will be occasions where there may be different reasons which may be assigned to conduct. His Honour referred, then, to the dicta of Lord Hoffman in Shah, upon which counsel for Mr Gersten relied. In the passage cited, Lord Hoffman said:
"Suppose oneself in Germany in 1935. There is discrimination against Jews in general, but not all Jews are persecuted. Those who conform to the discriminatory laws, wear yellow stars out of doors and so forth can go about their ordinary business. But those who contravene the racial laws are persecuted. Are they being persecuted on grounds of race? In my opinion, they plainly are. It is therefore a fallacy to say that because not all members of a class are being persecuted, it follows that persecution of a few cannot be on grounds of membership of that class. Or to come nearer to the facts of the present case, suppose that the Nazi government in those early days did not actively organise violence against Jews, but pursued a policy of not giving any protection to Jews subjected to violence by neighbours. A Jewish shopkeeper is attacked by a gang organised by an Aryan competitor who smash his shop, beat him up and threaten to do it again if he remains in business. The competitor and his gang are motivated by business rivalry and a desire to settle old personal scores, but they would not have done what they did unless they knew that the authorities would allow them to act with impunity. And the ground upon which they enjoyed impunity was that the victim was a Jew. Is he being persecuted on grounds of race? Again, in my opinion, he is. An essential element in the persecution, the failure of the authorities to provide protection, is based upon race. It is true that the answer to the question "Why was he attacked?" would be "because a competitor wanted to drive him out of business". But another answer, and in my view the right answer in the context of the Convention, would be "he was attacked by a competitor who knew that he would receive no protection because he was a Jew."
31 The purpose of his Honour's quotation from Lord Hoffman is clear enough from the comments which follow it. The point which his Honour makes is that there may be different reasons for particular acts which constitute persecution. It is not necessary that the Convention reason relied upon be the sole reason for the persecution, as the Tribunal in Chen appeared to his Honour to have thought. On the facts of the particular case and when regard is had to the objects of the Convention and the Australian law which gives effect to it, the persecution which the child suffered was "for reasons of" its membership of a social group, being the group described as "black children". His Honour's view echoes the comments of French J in Jahazi v Minister for Immigration and Ethnic Affairs (1995) 61 FCR 293 to which reference was also made in the submissions made on behalf of Mr Gersten.
32 That there will be cases, and Chen is but one example, where the persecution feared is inflicted for multiple reasons (which include a Convention reason) may readily be accepted. Likewise, it may be accepted that in such a case it will be open to the Tribunal to find that the feared persecution is for a Convention reason. But, it is another thing to say that the Tribunal erred in the present case in law in arriving at the conclusion which it did. It is necessary to refer to the facts which the Tribunal found.
33 First, it is necessary to identify the persecution which is claimed to have existed in the past and which is said to provide the foundation for the well-founded fear of persecution in the event that Mr Gersten is returned to his country of nationality. This was, on Mr Gersten's case, primarily, his being gaoled. For the purposes of this submission the claim that being placed in a perjury trap itself constituted persecution need not be considered for it was the finding that Mr Gersten's gaoling was not persecution for reasons of his political opinion which was the subject of attack in this submission (including the special and adverse treatment he claimed to have received in gaol). Then it is necessary to determine, having regard to the objects which the Convention serves to promote, whether the identified persecution was for reasons of the claimant's political opinion.
34 The Tribunal made no specific finding as to whether the investigation which was launched against Mr Gersten was itself politically motivated. It said no more than that Mr Gersten "may have been right" in asserting that the investigation was carried out in bad faith. However the Tribunal concluded, and the conclusion was to say the least open to it, that Mr Gersten's gaol term arose in the circumstances, not because an investigation was launched, but rather because he had refused to answer questions which he had been ordered to answer by Judge Dean. While it is true that Mr Gersten may not have been placed in the position of having an investigation being instigated into his affairs without his opponents being motivated by a political view adverse to his, that was not the reason he was gaoled.
35 It may be noted that Mr Gersten did not suggest that Judge Dean had done anything other than afford him a fair trial or that her Honour was herself biased against him. In these circumstances it was open to the Tribunal to find as a fact that his being gaoled was not persecution for reasons of any political opinion he held. There is nothing in the Tribunal's reasons which suggests that it applied, as was suggested, a "but for" test in arriving at its conclusion or that it failed to recognise that persecution may be activated by multiple reasons and failed to take account of one of those reasons.
36 In other words, the reasons of the Tribunal do not suggest that it erred, as counsel for Mr Gersten claimed, in applying some wrong test of causation.
