Why can minors not give legal consent for medical care?

Minors cannot legally consent to medical care due to the principle that individuals must have the legal capacity to make informed decisions about their health. This capacity generally includes the ability to understand the consequences of their choices and to make decisions in their own best interests. Since minors are often deemed not to possess the necessary maturity or understanding to fully evaluate the risks and benefits associated with medical procedures or treatments, they cannot provide legal consent.

This means that in many jurisdictions, healthcare providers need to obtain consent from a parent or guardian who has the legal authority to make those decisions on behalf of the minor. As a result, minors typically rely on their parents or guardians to grant permission for medical care, making the notion of minors having the autonomy to consent or refuse care inaccurate in this context.
