移民局为了防止黑民在境内利用配偶签证钻移民局的空子，获得签证。规定如果申黑民已经超过28天，就需要有compelling reason 来申请配偶签证。但是这个规定也误伤了一些合法的过桥签证持有人。
虽然在1996 年法律刚刚颁布的时候给出的解释是 长期的关系可以考虑3001的豁免。
Explanatory Statement for the Migration Regulations (Amendment) 1996 No 75 states that a genuine long-standing relationship may justify waiver because of the hardship which could otherwise result. It also provides that: “The introduction of a waiver provision recognises the hardship that can result if an unlawful non-citizen wishing to remain in Australia on spouse grounds is obliged to leave Australia and apply from overseas.” This emphasises the primary role of hardship in the consideration of “compelling reasons”.
“not intended to facilitate persons who can leave Australia and apply for a partner visa offshore”. Rather, it is aimed at persons who, due to involuntary circumstances beyond their control like illness or incapacity, became unlawful non-citizens and were prevented from regularising their immigration status.
也就是说除非是由于不可抗力，你成了黑民就不能得到豁免。虽然法院对这个问题有不同看法， 法院认为根本就没有这种黑民就不能得到豁免的说法。 比如 Crennan J in Paduano v Minister for Immigration and Multicultural and Indigenous Affairs  FCA 211; 143 FCR 204 at , stating “there is nothing in the express wording, or the context, which indicates that ‘compelling reasons for the absence’ must be confined to reasons incorporating an involuntary element, involving circumstances beyond a person’s control”.
但是归根到底，这个3001 还是属于签证官或者AAT的自由裁量范围。比如 These “compelling reasons” must be sufficiently powerful to lead the relevant decision-maker to make a positive finding in favour of waiving the required criteria: Babicci v Minister for Immigration and Multicultural and Indigenous Affairs  FCAFC 77; 141 FCR 285,  (Tamberlin, Conti and Jacobson JJ).
所以如果你是黑民，如果不是由于不可抗力变成黑民，基本上是无法在移民局取得3001的豁免。如果去AAT 上庭，如果你有长期关系 目前来看你的胜率是25%，或者有小孩，你的胜率目前来看是50%。
