This amendment would mean that the written request would have to be signed and dated after the person was informed that they have a serious and incurable illness, that they're in a state of advanced and irreversible decline in capability, and that the illness, disease, or disability is causing them enduring and intolerable suffering.
The legal effect of the amendment is that the person would have to be informed of their own suffering. It's the (c) element of proposed subsection 241.2(2), because you're capturing all four elements.
