In Chu Keung Lim the HCA substantially upheld the validity of amendments to the Migration Act that provided for detention in custody of asylum seekers. Brennan, Deane and Dawson JJ formulated a broad constitutional principle that the involuntary detention of a citizen in custody may only be ordered by a court in consequence of a judicial finding of criminal responsibility
But this was applicable only to cases under a law of the CTH since it was based on exclusive vesting of CH III powers in CTH courts. In Kable a related principle for states on the basis that state courts exercising CTH judicial power may not be given functions incompatible with the exercise of that power
Both these principles remain uncertain
Chu Keung Lim v Minister for Immigration, Local Government and Ethnic Affairs (1992) 176 CLR 1 Brennan, Deane and Dawson JJ stated the relevant principle:

Boilermakers’ Case – The HCA and PC treated CH III as excluding any combination of non-judicial power with the judicial power of the CTH
Hilton v Wells – the majority accepted an exception to the Boilermakers principle – a federal judge can perform non-judicial functions provided they act as a persona designate and not in a judicial capacity
Grollo v Palmer – this exception doesn’t apply if the functions to be performed are incompatible with the holding of judicial office
In Kable the scope of the incompatibility doctrine was significantly expanded from its status as a mere exception to the persona designata rule
Kable v Director of Public Prosecutions (NSW) (1996) 189 CLR 51 Facts: The Community Protection Act 1994 (NSW) (‘the Act’) empowered the NSWSC to make preventive detention orders.
Kable was in gaol for manslaughter of his wife and he had written letters apparently threatening the safety of his children and wife’s sister with whom they were living. One of the arguments was based on the separation of powers (that the section was a ‘legislative usurpation of judicial power’) which has been held not to operate at the State level. Instead the “incompatibility” doctrine was invoked – it was held that the Act was ‘incompatible’ with the exercise of federal judicial power (not that the power was an inappropriate exercise of State legislative power). Only Brennan CJ and Dawson J dissented. Toohey J began by making the point that most of the other judges appeared not to regard as necessary, was that federal jurisdiction was invoked in this case. Toohey J remarked that the NSWSC was exercising federal jurisdiction under s 39 of the Judiciary Act because it concerned an implication to be drawn from the CTH Constitution that legislation, federal or State, directed against or discriminating against an individual is invalid.
Gaudron J noted that although it has been said that CH III in the Constitution draws a clear distinction between federal and State Courts – the sections do not draw any such distinction. She went on:
Is the power conferred by s 5(1) repugnant or incompatible with the exercise of the judicial power of the CTH
