"Planned Parenthood's concern with family planning and family health necessarily includes concern with the availability of abortion and with the compelling problems which result from restrictive abortion laws which make medically safe, legal abortions unavailable to many women. Planned Parenthood has adopted a policy on abortion which states in part: The optimum method of birth control is the consistent employment of effective contraception but in practice this goal is sometimes not achieved. It is, therefore, desirable that provisions respecting abortion not be contained in state Criminal Codes. Planned Parenthood believes that since abortion is a medical procedure, it should be governed by the same rules as apply to other medical procedures in general when performed by properly qualified physicians with reasonable medical safeguards."
