Linking the father's entitlement to the mother's in this manner would have the effect of denying the father his leave entitlement in his own right, as provided for under section 16 of the principal Act. A similar issue arises in subsection (1A)(d). Subsections (1A)(b), and (c) also give rise to inconsistencies in section 16 of the principal Act by tying the father's entitlement to leave to the mother's leave which has been postponed.
