More on the Registrar

Just had a thought. The HFEB being debated at the moment with it's third reading on the 14th July in the Commons seeks to amend the Births and Deaths Registrations legislation to permit female same sex partners to be registered as the parents on birth certificates where the child has been born via IVF procedures. Will the Islington ruling therefore allow registrars from opting out of registering the births of such children on the grounds that this is against their religious beliefs? Will they permitted to only being allowed to register the births of children born of woman and man? The implications of this ruling are ridiculous?
