Nothing in this article shall require a hospital or other medical facility or physician to admit any patient under the provisions of this article for the purpose of performing an abortion. In addition, any person who states in writing an objection to any abortion or all abortions on moral or religious grounds shall not be required to participate in procedures which will result in such abortion; and the refusal of the person to participate therein shall not form the basis of any claim for damages on account of such refusal or for any disciplinary or recriminatory action against the person. The written objection shall remain in effect until the person revokes it or terminates his association with the facility with which it is filed.
