The Woman! Woman's body, woman's decision... I believe there was a case in the US (of course!) where a woman wanted to birth her breech baby vaginally & was refusing c/section. Her ex partner tried to get an interim order to insist on the baby being born "in the safest way" which was deemed by the medical staff as being vaginally... I believe that in the end she birthed vaginally as until the baby was born she had the right to decide over her body...

Not sure though how this would stand legally here... For, I have known cases where authoritites became involved when suspicious of a woman's intent to birth VBAC at home...
