The impact of third-party authorization requirements on abortion-related outcomes: a synthesis of legal and health evidence

OBJECTIVES: This review synthesizes legal and health evidence to demonstrate the health and human rights impacts of third-party authorization requirements (TPAs) on abortion seekers. RESULTS: The synthesized evidence substantiates the pre-existing position in international human rights law that requirements that abortion be authorized by third parties like parents, spouses, committees, and courts create barriers to abortion, should not be introduced at all, or should be repealed where they exist. CONCLUSIONS: The review establishes that rights-based regulation of abortion should not impose TPAs in any circumstances. Instead, the provision and management of abortion should be treated in a manner cognizant with the general principles of informed consent in international human rights law, presuming capacity in all adults regardless of marital status and treatment sought, and recognizing the evolving capacity of young people in line with their internationally-protected rights.
