(a)   failure to give the notice required by section 42, or a false statement, defect or error in such a notice;

(b)   failure of the parties, or either of them, to make or subscribe a declaration as required by section 42, or a false statement, defect or error in such a declaration;

(c)   failure to produce to the authorised celebrant a certificate or extract of an entry or a statutory declaration as required by section 42, or a false statement, defect or error in such a statutory declaration;
