Assessing Capacity to Refuse Medical Treatment on Religious Grounds

by Michelle Flynn

Question(s) at stake

1) Whether a court can authorize medical personnel to administer medical treatment to an adult patient who is not of unsound mind and has refused such treatment on religious grounds. 2) Whether a mother’s constitutional rights of autonomy, self-determination, and free practice of religion would prevail over the interests of the child under the Constitution.

Outcome of the ruling

The Court affirmed that the right of a properly informed adult with full capacity to refuse medical treatment, for religious or other reasons, was constitutionally protected.

The question of balancing the constitutional rights of a new-born child against the mother’s constitutional rights of autonomy, self-determination, and free practice of religion was moot as the refusal of a blood transfusion was deemed to be invalid in this case.
