Hospice Palliative Care Act (hereinafter referred to as the Act) is the main regulation of life-sustaining treatments in Taiwan. While the Act narrowed the applicable subjects’ scope to terminal illness patients, it excluded the patients who suffered from non-terminal illness from the right to refuse life-sustaining treatments. To ensure the purpose of the Act comes into effect, the thesis discusses other countries’ legislation, legal judgments, and scholars' opinions on whether non-terminal illness patients who relied on life-sustaining treatment should be able to decide on receiving or refusing life-sustaining treatments, and limitations on the rights to avoid abuse. Based on the analysis, the thesis recommends the legislators to establish the supporting measures, such as the supervision system, in hopes of helping everyone embrace real peace and dignity during last days of life.
