"Equality in the law is all." In this kind of area what "equality" means isn't always too clear. For example I think there are very few people who would say that it should mean that a man should under any circumstances be entitled to force a woman to have an abortion, just because he is the father. And if the partners had made some quasi-legal agreement to that effect, I would trust that it could never be enforceable.

I think Harvey is wrong about what a commitment to "equality" would imply, if the law were changed so that that neither parent would have the right to insist on the destruction of a fertilised embryo.

Surely equality here would mean in principle that, if there woman who was willing to carry it to term, for example a new partner, she would be allowed to do so? Not at all the same thing.
