Subject to Rule 37 [Rule 530], every natural person has a right to refuse to disclose in an action or to a police officer or other official any matter that will incriminate him or expose him to a penalty or a forfeiture of his estate, except that under this rule:

(a) no person has the privilege to refuse to submit to examination for the purpose of discovering or recording his corporal features and other identifying characteristics or his physical or mental condition;

(b) no person has the privilege to refuse to obey an order made by a court to produce for use as evidence or otherwise a document, chattel or other thing under his control if some other person or a corporation or other association has a superior right to the possession of the thing ordered to be produced;

(c) no person has a privilege to refuse to disclose any matter which the statutes or regulations governing his office, activity, occupation, profession or calling, or governing the corporation or association of which he is an officer, agent or employee, require him to record or report or disclose except to the extent that such statutes or regulations provide that the matter to be recorded, reported or disclosed shall be privileged or confidential;

(d) subject to the same limitations on evidence affecting credibility as apply to any other witness, the accused in a criminal action or a party in a civil action who voluntarily testifies in the action upon the merits does not have the privilege to refuse to disclose in that action, any matter relevant to any issue therein.
