§ 507-e. Uniformed court officers and peace officers; certain disabilities. Notwithstanding any provision of this chapter or of any general, special or local law to the contrary, any member who is a uniformed court officer or peace officer in the unified court system who contracts any condition of impairment of health caused by diseases of the heart, resulting in disability or death to such court officer or peace officer, presently employed, and who shall have sustained such disability while so employed, shall be presumptive evidence that such disability was incurred in the performance and discharge of duty and the natural and proximate result of an accident, unless the contrary be proved by competent evidence; provided, however, that prior to entry into service, such member successfully passed a physical examination which failed to disclose evidence of any disease or other impairment of the heart.
