(a) No application for the issuance of any insurance policy or contract shall be admissible in evidence in any action relative to such policy or contract, unless a true copy of the application was attached to or otherwise made a part of the policy when issued and delivered. This provision shall not apply to policies or contracts of industrial life insurance.
(b) If any policy of life or disability insurance delivered in this territory is reinstated or renewed, and the insured or the beneficiary or assignee of the policy makes written request to the insurer for a copy of the application, if any, for such reinstatement or renewal, the insurer shall, within fifteen days after receipt of such request at its home office or at any of its branch offices, deliver or mail to the person making such request, a copy of such application. If such copy is not so delivered or mailed, the insurer shall be precluded from introducing the application as evidence in any action or proceeding based upon or involving the policy or its reinstatement or renewal.
