delivered the Opinion of the Court.
This case involves an appeal of a trial court’s order permanently enjoining appellants Jean Rosburg and Barbara Parker from practicing midwifery without a license as prohibited by sections 12-36-106(l)(f) and 12-36-106(2), 5 C.R.S. (1985). 1 The midwives argued to the trial court that section 12-36-106(l)(f) unconstitutionally infringed the right of privacy of pregnant women to choose their method of childbirth and that the section was unconstitutionally vague. The trial court ruled that the midwives did not have standing to assert the privacy right of pregnant women 2 and that section 12-36-106(l)(f) was not unconstitutionally vague. The midwives appealed to this court pursuant to section 13-4-102(l)(b), 6A C.R.S. (1987).
On appeal the midwives again contend that they have standing to assert pregnant women’s constitutional right to privacy and that section 12-36-106(l)(f) violates pregnant women’s privacy right. Alternatively, the midwives argue that the classification of licensed nurse-midwives versus lay midwives created by section 12-36-106(l)(f) violates the midwives’ right to equal protection of the law. The midwives also argue on appeal that section 12-36-106(l)(f) is unconstitutionally vague.
We agree with Rosburg and Parker that they have standing in this case to assert the privacy right of pregnant women. We disagree, however, that the prohibition against practicing midwifery without a license infringes a privacy right of pregnant women. We hold that section 12-36-106(l)(f) does not violate the midwives’
I. .
To have standing to assert the rights of third parties not before the court, the parties before the court must demonstrate injury to themselves sufficient to guarantee concrete adverseness.
People v. Seven Thirty-Five East Colfax, Inc.,
The standing of a vendor of goods or services to assert the constitutional rights of customers where the challenged statutory sections are addressed to the vendor is well-established.
See, e.g., Carey v. Population Services International,
All three of the prudential limitations placed on third-party standing also are present in vendor-customer cases such as this. In these cases, the constitutional rights of the customers are “inextricably bound up” with the activity of the vendor prohibited by the statute.

Olson,
The crucial issue is whether Rosburg and Parker can show, for the purpose of third-party standing, that the alleged injury to pregnant women is to a legally protected interest. Rosburg and Parker must demonstrate that pregnant women have a constitutional right to privacy that arguably has been abridged by the prohibition against the unlicensed practice of midwifery in section 12-36-106(l)(f). The midwives base their claim solely on the federal constitution.
This court has recognized a fundamental privacy right encompassed by the liberty interest protected by the due process clause of the United States Constitution.
In addition, we previously have conferred standing on the grounds that an alleged injury implicated a legally protected interest without resolving whether the alleged injury, on the merits, constituted an injury to a legally protected interest.
See Olson,
We also note that public policy favors the recognition of third party standing in a case like this where the challenged law imposes a duty on the party who is before the court. Denying the dutyholder standing to assert the rights of third parties would encourage a fortuitous pattern of results. The statute at issue would impose a duty on the dutyholder if no third party previously had challenged the statute but the statute no longer would impose the duty if a third party previously had challenged the statute.

Conferring standing on Rosburg and Parker to raise and fully argue the issue of whether the prohibition violates pregnant women’s privacy right also enables us fully to address the privacy right issue rather than
We find that standing is appropriate in this case. Rosburg and Parker are subject to direct injury under the statute at issue, consideration of the prudential limitations on standing weighs heavily in favor of standing, and neither the Supreme Court nor this court has addressed the issue of the privacy right of pregnant women that Rosburg and Parker seek to assert in this case. Moreover, to deny standing in cases such as this would encourage a fortuitous pattern of results and obscure the issue of the scope of the constitutional right at issue.
II.
We now proceed to the merits of Rosburg’s and Parker’s argument that the prohibition against the unlicensed practice of midwifery violates the right of privacy of pregnant women. In
Roe v. Wade,
Under these holdings from Roe, the state’s prohibition against the unlicensed practice of midwifery does not violate pregnant women’s privacy right. While the right of privacy encompasses some personal choices related to procreation, it does not include the personal choice of whether to utilize a lay midwife to assist in childbirth. The right of privacy has not been interpreted so broadly. We therefore hold that the state may, out of its interest in protecting the health of the mother and her child, proscribe the unlicensed practice of midwifery without violating the privacy right of the pregnant woman.
III.
The midwives argue that the provisions of section 12-36-106(l)(f) violate the midwives’ Fourteenth Amendment right to equal protection of the law. Specifically, the midwives contend that the prohibition of lay midwifery impermissibly discriminates between lay midwives and licensed nurse-midwives. We disagree.
Because no fundamental right or suspect class is involved in the prohibition against the unlicensed practice of midwifery, we examine section 12 — 36—106(l)(f) under the rational basis test.
See, e.g., Austin v. Litvak,
The test requires that this court “conduct a serious and genuine judicial inquiry into the correspondence between the classification and the legislative goals.”
Id.
However, “[although parties challenging legislation under the Equal Protection Clause may introduce evidence supporting their claim that it is irrational, they cannot prevail so long as ‘it is evident from all the considerations presented to [the legislature], and those of which [the court] may take judicial notice, that the question is at least debatable.’ ”
Minnesota v. Clover Leaf Creamery Co.,
The prohibition of lay midwifery under section 12-36-106(l)(f) clearly satisfies the rational basis test. The classification of licensed nurse-midwives versus lay midwives is rational and reasonable. Testimony at trial revealed that nurse-midwives practicing in Colorado are required to be registered nurses, must have an additional year of midwifery training and also must participate in continuing education. The state’s expert in pediatrics and obstetrics testified that the state’s certification of nurse-midwives and prohibition of lay midwifery was “very reasonable and rational” and explained his reasoning as follows:
I think the — the entry point of the skill level that’s required of a basic nurse, which is the knowledge of pathophysiolo-gy of labor and delivery, technical skills, counseling skills, knowledge of problems that could arise during labor and delivery, I think is essential. That knowledge base is essential. I think on top of that the nurse midwifery training adds to that the ability to make decisions around that knowledge, decisions being for prenatal care, during labor and delivery, and then adding to that the ability to handle a newborn who needs resuscitation ... at the time of birth is not a skill that [a lay midwife] has and also would require further training.
Rosburg, on the other hand, testified that her formal education consisted of completion of high school and one year of college. 5
Licensed nurse-midwives also practice under different protocols from lay midwives. 6 Nurse-midwives are required to practice under the supervision of a backup physician; lay midwives are not required to have a backup physician. The nurse-midwives also take several prescription medications to the home to ensure the safety of the mother and child. When asked about using prescription medications, Rosburg testified that she previously had used an anesthetic, but did not remember its name and did not know whether it was a prescription drug in Colorado. She had procured the drug in Mexico. These differences between the practice of lay midwives and certified nurse-midwives in Colorado clearly make the legislature’s distinction between the two groups rational and reasonable.
The certification of licensed nurse-midwives and prohibition against lay midwives also is rationally related to a legitimate governmental interest. It is beyond question that the state has a legitimate interest in protecting the health and safety of the mother and her child.
See, e.g., Roe,
The certification of licensed nurse-midwives and prohibition against lay midwives also is rationally related to the State’s interest in protecting the life and health of the mother and her child. As discussed above, the nurse-midwives maintain strict certification requirements and practice under safer protocols than lay midwives. These, requirements and practices directly impact the health and safety of the mother and her child. 7
IV.
Rosburg and Parker also contend that section 12 — 36—106(l)(f) is unconstitutionally vague, both facially and as applied to them. Appellants argue that the phrase, “the practice of midwifery,” renders the section unconstitutionally vague because the phrase is not defined in the statute. Appellants also point out that the Board of Medical Examiners (the “Board”) has not adopted a definition of what constitutes midwifery and that the Board decides whether a practice constitutes midwifery on a case-by-case basis. Despite these contentions, we hold that “the practice of midwifery” is not unconstitutionally vague.
The criteria by which a statute challenged on vagueness grounds is judged are well-established. Statutes are presumed to be constitutional and a party as-setting that a particular statute is unconstitutional must prove the unconstitutionality beyond a reasonable doubt.
See, e.g., Eckley v. Colorado Real Estate Commission,
However, words and phrases used in statutes are to be considered in their generally accepted meaning, and the court has a duty to construe the statute in such a way that it is not void for vagueness when a reasonable and practicable construction can be given to its language.
R & F Enterprises, Inc. v. Board of County Commissioners,
Although “midwifery” is neither defined in the statute nor defined by the Board, “midwife” is a term of common usage and
We conclude that the term “practice of midwifery” is not unconstitutionally vague on its face. Constructions of the terms “midwife” and “midwifery” from common usage, legal and non-legal dictionaries, and case law are nearly unanimous in defining midwifery as assisting at childbirth. Women not properly licensed who assist at childbirth, therefore, are sufficiently aware that their conduct is prohibited. 9 Neither the Board nor prosecutors are left with the unfettered discretion that the doctrine of vagueness seeks to avoid.
The term “practice of midwifery” also is not unconstitutionally vague as applied to Rosburg and Parker. They also were aware of what conduct was prohibited by the statute and their conduct fell within the prohibition. Rosburg testified at trial that her profession was that of a lay midwife and she defined the term in accordance with applicable dictionary and legal definitions. 10 The trial court also specifically found that Rosburg and Parker had engaged in the practice of midwifery.
Accordingly, we uphold the constitutionality of section 12 — 36—106(l)(f) and affirm the trial court’s order permanently enjoining Rosburg and Parker from practicing midwifery without a license.
Notes
. Section 12 — 36—106(l)(f) specifies that the "practice of midwifery except services rendered by nurse-midwives licensed [pursuant to the Nurse Practice Act] and certified by the American college of nurse-midwives” constitutes the practice of medicine. Section 12-36-106(2) prohibits practicing medicine without a license.
. No pregnant women have been parties to this case.
. The abortion cases of
Doe v. Bolton,
. We also again note that to deny Rosburg and Parker standing to raise the issue of the privacy right potentially would permit the dilution of the pregnant women’s rights without an argument made on behalf of the women whose rights might be diluted.
. Parker elected not to testify at trial, citing her privilege against self-incrimination.
. Because lay midwives are unregulated, anyone can hold herself out as a lay midwife and there are no required protocols as such. Rosburg, however, testified that she was a member of the Colorado Midwives Association, an association which had adopted certain protocols.
. Rosburg and Parker also complain that the prohibition against lay midwives prevents women, particularly poor women in rural areas, from having home births because of the unavailability and unwillingness of nurse midwives or physicians to do home births. Testimony at trial demonstrated that the practice of nurse midwifery in Colorado is growing. Moreover, the legislature may, in its discretion, address one phase of a problem and neglect others without violating the equal protection clause.
See, e.g., Williamson v. Lee Optical,
. The parties dispute under what standard the vagueness' of section 12 — 36—106(l)(f) should be scrutinized.
See Parrish v. Lamm,
. There are, of course, exceptions to this prohibition in emergency situations where people not licensed as nurse midwives or physicians assist in childbirth.
. We again note that Parker elected, out of her right against self-incrimination, not to testify on her own behalf.
