I really don't think there is much of a precedent here.
The courts (two decisions) were following what the Canadian Supreme Court and the Alberta statutes also stated. The mothers actions were and still are also very disgusting.
BTW - there are lots of ways this can be appealed and can easily end up at the supreme court. This is not over yet.
The most important news is that this young girl is still alive and the cancer is in remission.
