And if you want to codify it into law, please provide some real world examples including forcing the woman to have or not have an abortion.
Who said anything about forcing a woman into having an abortion? Discussing =/= forcing. Discussing == having a say/opinion on that matter at hand.
And as to who the 'tiebreaker' is, I'm still waiting for that 'discussion'. As I said, I have no answer. I haven't been in that situation. But I do know people, who, in the end, came to a 'middle ground', so to say. After discussing it, and coming to a standstill, they both came, male and female, with research/statistics, and discussed it, again. Neither really had a 'deciding factor'. They both came to terms with a compromise.
The woman has final say.
What if the woman is incapable of having the final say?
