Northern Ireland (Executive Formation) Bill

I am sorry; I must be missing something here. Can my noble friend just explain to me why it is that if this amendment proceeds the timescale for the foetus is not the same as in the legislation in the 1967 Act? Foetal viability—whether it survives—is gauged only after the foetus is born and becomes a child. What does 22 to 28 weeks refer to? I have not been able to find it in any of the words on any of the papers available tonight.
