the test is whether you as an individual in obtaining such information, able to misuse such data being so released and if you so misuse them knowing that you are not entitled to is also liable for an offense thus as guilty as the individual/corporation that released it.

the rationale of PDPA is to protect consumerism and not to instigate frivolous litigation thus the next question to be asked is whether are you able to obtain any benefits (even fringe) from possession such not entitled data?
there is no such thing as a "bankrupty order"; just adjudication order and receiving order (AO:RO for short). you said you "served" the "bankruptcy order", i assumed it is your summon for the defendant to appear in court to defend his or her case?
