In a case somewhat confusingly called The Public Trustee of Queensland v The Public Trustee of Queensland & Ors [2014] QSC 47, the  court was required to consider whether a person could remain as an executor and beneficiary under a will, despite having been convicted of having assisted in the suicide of the deceased.

The court noted that the answer was provided by legislation:

[19]     In this State, the law is clear. A person who assists the suicide of someone else cannot act as that person‟s executor, or take an interest in his or her estate. The court has no discretion to modify the application of that rule. Saying nothing as to the facts of this case, I observe that it is irrelevant that the offender may have been motivated to ease suffering or to have acted at the request of the deceased.
[20]      If there is to be any change in that arena, it is a matter of high public policy appropriate for consideration by the legislature, not determination by the courts. I should say that I am not to be taken to be inviting any such legislative consideration.
