A Hospital in Qld. Australia sought orders to allow a blood transfusion on a minor if necessary. This occurred on the 12th June 2015.
The child was 7 years old and required a liver transplant within the next two or three years otherwise death was seen as inevitable. With this procedure there is a 95% likelihood that a blood transfusion would be required so the Hospital wanted to ensure that authority was in place beforehand as the JW parents refused to consent. However, they did indicate that they would obey a court order if the hospital was given authorization to administer blood.
As expected, the Hospital/Doctors were granted this permission.

It appears to be the general policy of JW parents to accept any court orders and not to intervene in blood transfusions. Yet their no. 1 rule is that when man's laws conflict with God's laws they will uphold God's laws. They therefore are not doing this in the case of their children.
It's a topic they do not discuss in their publications much these days (children and blood transfusions). There is an article back in 1967 12/1 that does go into some detail. These are the main points
Christian fathers are obliged to teach this law and enforce it with regard to their minor children, for by God’s law the fathers are the spiritual, religious guardians as well as the domestic parental caretakers of their underage children. The Christian witnesses of Jehovah today recognize that fact and follow the divine rule of conduct. They endeavor to keep their children from violating God’s law to Noah and also the Jerusalem Council’s decree. (Eph. 6:4) Rightly they try to protect their children from taking foreign blood into them.
Do parents who are Jehovah’s witnesses really have the right to do this? Certain doctors, judges and lawmakers blind themselves to God’s law and to religious liberty and to Christian conscience and say No! These flouters of God’s law that applies to Christians claim that, when Jehovah’s witnesses refuse to let their children have a blood transfusion when a mere human doctor orders them to have it, Jehovah’s witnesses are dangerous parents to have over children and they lose their right to the guardianship of their own flesh-and-blood children. Such children must therefore become the wards of the political State, even in States where there is a separation of Church and State.
22 Thus it comes about that judges have had children taken from their own Christian parents and placed in the hands of appointed guardians that believe in transfusions. These have had the bodies of these seized children assaulted with a transfusion in shameful disregard of God’s law and conscientious objections of the Christian parents. If a child survives such a forced transfusion, such violators salve their consciences for having “saved a life.”....
Either rejecting blood transfusions are God's laws or not. In the case of children, however, it is not the case, they will allow it if ordered by the court and therefore choose man's law over God's law (and this is nothing to complain about).
Their convictions can become seriously weakened when other problems come into play. For instance, being charged and jailed if they were to remove their child from hospital prior to a court ordered blood transfusion being administered. The publicity and backlash from the public would prove too negative for them.
This does demonstrate that there are circumstances in which they do permit blood transfusions by not actively preventing it from being administered. Their double standards should send out warning signals to any JW that their stance on blood is not genuine.
