The petitioners also point out that Section 7 of the assailed legislation exempts hospitals operated by religious groups from rendering reproductive health service and modern family planning methods. It is unclear, however, if these institutions are also exempt from giving reproductive health information under Section 23(a)(l), or from rendering reproductive health procedures under Section 23(a)(2). Finally, it is averred that the RH Law punishes the withholding, restricting and providing of incorrect information, but at the same time fails to define "incorrect information." The arguments fail to persuade. A statute or act suffers from the defect of vagueness when it lacks comprehensible standards that men of common intelligence must necessarily guess its meaning and differ as to its application. It is repugnant to the Constitution in two respects: (1) it violates due process for failure to accord persons, especially the parties targeted by it, fair notice of the conduct to avoid; and (2) it leaves law enforcers unbridled discretion in carrying out its provisions and becomes an arbitrary flexing of the Government muscle.255 Moreover, in determining whether the words used in a statute are vague, words must not only be taken in accordance with their plain meaning alone, but also in relation to other parts of the statute. It is a rule that every part of the statute must be interpreted with reference to the context, that is, every part of it must be construed together with the other parts and kept subservient to the general intent of the whole enactment.256 As correctly noted by the OSG, in determining the definition of "private health care service provider," reference must be made to Section 4(n) of the RH Law which defines a "public health service provider," viz: (n) Public health care service provider refers to: (1) public health care institution, which is duly licensed and accredited and devoted primarily to the maintenance and operation of facilities for health promotion, disease prevention, diagnosis, treatment and care of individuals suffering from illness, disease, injury, disability or deformity, or in need of obstetrical or other medical and nursing care; (2) public health care professional, who is a doctor of medicine, a nurse or a midvvife; (3) public health worker engaged in the delivery of health care services; or (4) barangay health worker who has undergone training programs under any accredited government and NGO and who voluntarily renders primarily health care services in the community after having been accredited to function as such by the local health board in accordance with the guidelines promulgated by the Department of Health (DOH) . Further, the use of the term "private health care institution" in Section 7 of the law, instead of "private health care service provider," should not be a cause of confusion for the obvious reason that they are used synonymously. The Court need not belabor the issue of whether the right to be exempt from being obligated to render reproductive health service and modem family planning methods, includes exemption from being obligated to give reproductive health information and to render reproductive health procedures. Clearly, subject to the qualifications and exemptions earlier
