(e) Whoever, not being authorized by this section, solemnizes a marriage, shall be fined $100, and in default of the payment of such fine shall be imprisoned not more than 30 days, and such marriage shall be void, unless it is in other respects lawful and is consummated with the full belief of either of the parties in its validity.
(f) Other than as provided in this subsection, nothing in this section shall be construed to require any individual, including any clergyperson or minister of any religion, authorized to solemnize a marriage to solemnize any marriage, and no such authorized individual who fails or refuses for any reason to solemnize a marriage shall be subject to any fine or other penalty for such failure or refusal. Notwithstanding the preceding sentence, a Clerk of the Peace who issues a marriage license, or a deputy thereof, shall be required to perform a solemnization of such marriage if requested by the applicants for such license.
