Thank you for the question.
My position is twofold. First of all, the idea of mature minors is, to a certain extent, oxymoronic. They require litigation guardians for all sorts of civil actions in our society, and we don't trust them to litigate on a number of issues. They're growing. They're learning about themselves. They are subject to sometimes unreasonable depression.
There is a reason the court mandated that physician-assisted death was for competent adult persons. There are two components of that. One is competence, and one is adulthood. It appears to me that there are very good reasons for that.
