@libramoon Ok so the doctor **must** approve in order to move forward (otherwise they are not mutually agreeing). So the answer is, the doctor has the authority and the final say. Any situation that requires mutual agreement is the same as giving the doctor the authority, which is the same as states that outlaw abortion but make medical exemptions, which, based on how you say it should work, would be what you support.
I myself dont agree with that. I do not think abortions should be illegal, they should be legal but only under very specific conditions. Late term abortions would and should need doctors to agree with the patients that it is medically needed (which apparently you also think should be the case).
