I've read you facts, used my knowledge of American law, which is not that different from Canadian law. Not only lawyers have declined your case. Appellate courts have stricken so many parts of it is barely viable at all. I've received loans on a future settlement in my personal litigation. You have standing. It is bizarre to represent an estate of an adult daughter who chose death rather than a blood transfusion.
Legally, this case has very bad facts and the likely bad outcome could chill blood transfusions against many more Witness claimants. Law is clumsy, as you can well see by now. There is probably not a parent alive who does not feel for your loss. Minus the clumsy lawsuit, your story is eloquent. Justice and law only mesh sometimes. Several newspapers report facts contrary to your own.
Imagine a foundation in your daughter' name to educate Witnesses in alternatives. Some sort of phone bank to support parents in similar situations. Buying a law suit is not a correct term. The US has a requirement of an actual case or controversy and standing was honed during the New Deal to limit law suits against large corporations. Since Canda is also c/l jurisidction, I assume Canada does.
The situation stinks. YOu could be such a powerful force if you moved on. No damages will ever begin to replace your daughter. Were it not for legal education, I would prob. think you r case had merit. Legal merit and merit are two different things.
