7.  The applicants were born in 1947 and 1968 respectively and live in Warrington. 8.  The first applicant, B, married A and this marriage ended in divorce in 1987. B and A had a son together, C. The first applicant then married D. The first applicant and D separated in August 1994 and the divorce was finalised on 9 July 1997. 9.  The second applicant, L, married C, the first applicant's son from his first marriage. The first applicant and the second applicant were therefore father-in-law and daughter-in-law. The second applicant and C separated in 1995 and their divorce was finalised on 8 May 1997. The second applicant and C have a son together, W. The first applicant is, therefore, W's grandfather. 10.  A relationship developed between the first and second applicants in 1995 after C had left the second applicant's matrimonial home. The applicants have been cohabiting since 1996. W lives with the applicants and only has sporadic contact with his father, C. W now calls the first applicant “Dad”. The applicants plan to adopt W which is permitted by domestic adoption law. 11.  In a letter dated 29 May 2002, the first applicant wrote to the Superintendent Registrar of Deaths and Marriages at Warrington Register Office to inquire about whether he could marry the second applicant. In a letter dated 13 June 2002, the Superintendent Registrar stated that under the relevant domestic legislation, it would be impossible for the applicants to marry unless A and C were both dead:
“... The only circumstances a marriage could be allowed between yourself and [L] would be if you had both attained the age of twenty one and you could produce evidence of the death of your son and his mother (your first wife).” 12.  The applicants subsequently sought legal advice on whether there was any remedy against the decision of the Superintendent Registrar but were advised by counsel that no remedy existed since the basis for the decision was primary legislation, namely, the Marriage Act 1949 as amended by the Marriage (Prohibited Degrees of Relationship) Act 1986.
