Dr. Andrea Mulligan:

It would be necessary to go for neutral characteristics. If we were going down the terminal illness route, we would be looking at proximity to death, I suppose, and then pain and ways to describe pain. We would be looking for ways to describe those in neutral, legal terms. We would also have to be looking at ways that somebody would be willing to assess. It is difficult. Other jurisdictions have done it. Input from doctors would definitely be needed to describe those things.
