The courts don't know about these people. Decisions are made by families, and physicians.
If families deciding to pull feeding tubes angers you, you better gear up.
If these decisions are contested, then we have a case like Terri's. Most aren't contested, because they are private situations between a family and a doctor.
I think the courts have an idea of the implications in terms of case load if these cases began to be contested en masse, as prompted by the spotlight shown on Terri's case.
