Can you tell me where you found this info? I can't locate anything that says her living will was not a legal document or that it was not specific, etc. The only articles with any info concerning her living will that I have read are WND 4/09/05, David Kupelian, Grandma airlifted to Medical Center; WND 4/7/05, Sarah Foster; News.Telegraph, 4/17/05, Jacqui Goddard in Miami. None of them say that there was anything legally wrong with her living will. Everything else is a blog or forum as I don't think this made it into the MSM. Thanks.
I don't have a reference handy, but one of the longer threads about Ms. Magouirk included links to a collection of documents including her living will (scanned) as well as a link to the Georgia statute which gives a model form for a living will. The line spacing and the wording of the second item in Ms. Magoirk's copy are changed so that a quick reading of her version would yield an interpretation opposite what one would get with the model form.
